This switches the intel_menlow driver to use deci_kelvin_to_celsius()
and celsius_to_deci_kelvin() in <linux/units.h> instead of helpers in
<linux/thermal.h>.
This is preparation for centralizing the kelvin to/from Celsius
conversion helpers in <linux/units.h>.
This also removes a trailing space, while we're at it.

The asus-wmi driver doesn't implement the thermal device functionality
directly, so including <linux/thermal.h> just for
DECI_KELVIN_TO_CELSIUS() is a bit odd.
This switches the asus-wmi driver to use deci_kelvin_to_millicelsius()
in <linux/units.h>.
The format string is changed from %d to %ld due to function returned
type.

Some server users set limits on the uncore frequency using MSR 620H, while
running latency sensitive workloads. Here uncore frequency controls
RING/LLC(last-level cache) clocks.
But MSR control is not always possible from the user space, so this driver
provides a sysfs interface to set max and min frequency limits. This MSR
620H is a die scoped in multi-die system or package scoped in non multi-die
systems.
When this driver is loaded, a new directory is created under
/sys/devices/system/cpu.
For example on a two package Skylake server:
$cd /sys/devices/system/cpu/intel_uncore_frequency
$ls
package_00_die_00 package_01_die_00
$ls package_00_die_00
max_freq_khz min_freq_khz initial_max_freq_khz
initial_min_freq_khz
$grep . *
max_freq_khz:2400000
min_freq_khz:1200000
initial_max_freq_khz:2400000
initial_min_freq_khz:1200000
Here, initial_max_freq_khz and initial_min_freq_khz are read only
attributes to show power up or initial values of max and min frequencies
respectively. Other attributes are read-write, so that users can modify.

Use our default values when wrong module-parameters are given, instead of
refusing to load. Refusing to load leaves the fan at the BIOS default
setting, which is "Off". The CPU's thermal throttling should protect the
system from damage, but not-loading is really not the best fallback in this
case.
This commit fixes this by re-setting module-parameter values to their
defaults if they are out of range, instead of failing the probe with
-EINVAL.

The current implementation of intel_pmc_core driver allows to reuse, but does
not reflect the exact number and names of IPs for a newer platform which
does not necessarily support all the IPs in the entries. The names and
number of these IPs might differ from its previous platforms. The number
of PCH IPs per platform is calculated based on PPFEAR_NUM_ENTRIES
defined, where each entry represents a bucket (8 bits). The platform can
support 'n' entries, but not necessarily all 'n * 8' IPs.
Create platform dependent bitmap structures to specify the exact number,
names of IPs while reusing the existing IPs.
The changes in this patch are preparatory to accommodate future SoCs
that might reuse the CNL/ICL PCH IPs, and to reflect the exact number of
IPs with its names.

It is common practice to place a comma after the last entry in an
initialized array to avoid the need to add one in future patches that
extend the array. But when the last element is a termination marker, the
comma could be harmful. Any new entries must be added before the
terminator (and the comma would prevent the compiler from issuing a
warning about an entry after the terminator).

As part of the cleanup of some remaining y2038 issues, I came to
fs/compat_ioctl.c, which still has a couple of commands that need support
for time64_t.
In completely unrelated work, I spent time on cleaning up parts of this
file in the past, moving things out into drivers instead.
After Al Viro reviewed an earlier version of this series and did a lot

The AML code implementing the WMI methods creates a variable length
field to hold the input data we pass like this:
CreateDWordField (Arg1, 0x0C, DSZI)
Local5 = DSZI /* \HWMC.DSZI */
CreateField (Arg1, 0x80, (Local5 * 0x08), DAIN)
If we pass 0 as bios_args.datasize argument then (Local5 * 0x08)
is 0 which results in these errors:
[ 71.973305] ACPI BIOS Error (bug): Attempt to CreateField of length zero (20190816/dsopcode-133)

And in our HPWMI_WIRELESS2_QUERY calls always failing. for read commands
like HPWMI_WIRELESS2_QUERY the DSZI value is not used / checked, except for
read commands where extra input is needed to specify exactly what to read.
So for HPWMI_WIRELESS2_QUERY we can safely pass the size of the expected
output as insize to hp_wmi_perform_query(), as we are already doing for all
other HPWMI_READ commands we send. Doing so fixes these errors.

The HP WMI calls may take up to 128 bytes of data as input, and
the AML methods implementing the WMI calls, declare a couple of fields for
accessing input in different sizes, specifycally the HWMC method contains:
CreateField (Arg1, 0x80, 0x0400, D128)
Even though we do not use any of the WMI command-types which need a buffer
of this size, the APCI interpreter still tries to create it as it is
declared in generoc code at the top of the HWMC method which runs before
the code looks at which command-type is requested.
This results in many of these errors on many different HP laptop models:
[ 14.459261] ACPI Error: Field [D128] at 1152 exceeds Buffer [NULL] size 160 (bits) (20170303/dsopcode-236)

This commit increases the size of the data element of the bios_args struct
to 128 bytes fixing these errors.

We need to convert all old gpio irqchips to pass the irqchip
setup along when adding the gpio_chip. For more info see
drivers/gpio/TODO.
For chained irqchips this is a pretty straight-forward
conversion. This driver requests the IRQ directly in the driver
so it needs to pass a NULL parent handler. We may revisit this
code later and pull reqular shared IRQ handler into
gpiolib, so leave a FIXME.

The .ioctl and .compat_ioctl file operations have the same prototype so
they can both point to the same function, which works great almost all
the time when all the commands are compatible.
One exception is the s390 architecture, where a compat pointer is only
31 bit wide, and converting it into a 64-bit pointer requires calling
compat_ptr(). Most drivers here will never run in s390, but since we now
have a generic helper for it, it's easy enough to use it consistently.
I double-checked all these drivers to ensure that all ioctl arguments
are used as pointers or are ignored, but are not interpreted as integer
values.

For APIC case of interrupt we don't fail a ->probe() of the driver,
which makes kernel to print a lot of warnings from the children.
We have two options here:
- switch to platform_get_irq_optional(), though it won't stop children
to be probed and failed
- fail the ->probe() of i2c-multi-instantiate
Since the in reality we never had devices in the wild where IRQ resource
is optional, the latter solution suits the best.

INPUT_POLLDEV.
Because the new polling coded does not allow peeking inside the poller
structure to get the poll interval, we change the "debounce" process to
operate on the time basis, instead of counting events.
We also fix error handling during initialization, as previously we leaked

This patch adds a quirk disabling keyboard backlight support for the
Dell Inspiron 1012 and 1018.
Those models wrongly report supporting keyboard backlight control
features (through SMBIOS tokens) even though they're not equipped with
a backlit keyboard. This led to broken controls being exposed
through sysfs by this driver which froze the system when used.

1. Fixes reporting brightness keys twice since it's already handled by
acpi-video.
2. Some models need a short delay when setting battery thresholds to
prevent a race condition when two processes read/write. (will be used later)
3. Matebook X (2017) handles micmute led through the "legacy" interface
which is not currently implemented. Use ACPI EC method to control
this led. (will be used later)

Move from WMI driver to platform driver. This move is necessary since
the driver is no longer a hotkeys driver only. Platform driver makes it
easier for users to access sysfs attributes under (i.e.
/sys/devices/platform/huawei-wmi) compared to wmi driver.
Use WMI device UID, AMW0 has a UID of HWMI. WMI0 is the device name
and doesn't have a UID so keep it as it is.

For APIC case of interrupt we don't fail a ->probe() of the driver,
which makes kernel to print a lot of warnings from the children.
We have two options here:
- switch to platform_get_irq_optional(), though it won't stop children
to be probed and failed
- fail the ->probe() of i2c-multi-instantiate
Since the in reality we never had devices in the wild where IRQ resource
is optional, the latter solution suits the best.

Here is the big driver core update for 5.4-rc1.
There was a bit of a churn in here, with a number of core and OF
platform patches being added to the tree, and then after much discussion
and review and a day-long in-person meeting, they were decided to be
reverted and a new set of patches is currently being reviewed on the
mailing list.
Other than that churn, there are two "persistent" branches in here that
other trees will be pulling in as well during the merge window. One
branch to add support for drivers to have the driver core automatically
add sysfs attribute files when a driver is bound to a device so that the
driver doesn't have to manually do it (and then clean it up, as it
always gets it wrong).
There's another branch in here for generic lookup helpers for the driver
core that lots of busses are starting to use. That's the majority of
the non-driver-core changes in this patch series.
There's also some on-going debugfs file creation cleanup that has been
slowly happening over the past few releases, with the goal to hopefully
get that done sometime next year.
All of these have been in linux-next for a while now with no reported
issues.

After changing the valid_mask for the struct gpio_chip
to detect the need and presence of a valid mask with the
presence of a .init_valid_mask() callback to fill it in,
we augment the gpio_irq_chip to use the same logic.
Switch all driver using the gpio_irq_chio valid_mask
over to this new method.
This makes sure the valid_mask for the gpio_irq_chip gets
filled in when we add the gpio_chip, which makes it a
little easier to switch over drivers using the old
way of setting up gpio_irq_chip over to the new method
of passing the gpio_irq_chip along with the gpio_chip.
(See drivers/gpio/TODO for details.)

Commit 871f1f2bcb ("platform/x86: intel_int0002_vgpio: Only implement
irq_set_wake on Bay Trail") removed the irq_set_wake method from the
struct irq_chip used on Cherry Trail, but it did not set
IRQCHIP_SKIP_SET_WAKE causing kernel/irq/manage.c: set_irq_wake_real()
to return -ENXIO.
This causes the kernel to no longer see PME events reported through the
INT0002 device as wakeup events. Which e.g. breaks wakeup by the (USB)
keyboard on many Cherry Trail 2-in-1 devices.

The validity of address PMC_BASE_ADDR_DEFAULT (i.e., 0xFE000000) is not

Commit 10a08fd65e ("ACPI: PM: Set up EC GPE for system wakeup from
drivers that need it") assumed that the EC GPE would only need to be
set up for system wakeup if either the intel-hid or the intel-vbtn
driver was in use, but that turns out to be incorrect. In particular,
on ASUS Zenbook UX430UNR/i7-8550U, if the EC GPE is not enabled while
suspended, the system cannot be woken up by opening the lid or
pressing a key, and that machine doesn't use any of the drivers
mentioned above.
For this reason, always set up the EC GPE for system wakeup from
suspend-to-idle by setting and clearing its wake mask in the ACPI
suspend-to-idle callbacks.

Merge tag 'v5.3-rc4' into next
Sync up with mainline to bring in device_property_count_u32 andother
newer APIs.
Notice that intel_button_array_enable() never disables the power
button which is the only one needed to wake up the system from
suspend-to-idle, so it can be safely called during suspend-to-idle
as well as during "regular" system suspend, and rearrange the
code in the driver's "suspend" and "resume" callbacks accordingly.
While at it, use pm_suspend_no_platform() to check if the current
suspend-resume cycle is suspend-to-idle, as that is the only
case when the device should be enabled while suspended.

Both intel-hid and intel-vbtn set a wakeup_mode flag causing them
to behave in a special way during system suspend and while suspended
in their "prepare" PM callbacks and clear it in their "resume" PM
callbacks. That may cause the wakeup_mode flag to remain set after
a system suspend failure (if some other driver's "suspend" callback
returns an error before the "suspend" callback of either intel-hid
or intel-vbtn is invoked).
After commit 10a08fd65e ("ACPI: PM: Set up EC GPE for system wakeup
from drivers that need it") that also affects the "wakeup mask" bit
of the EC GPE, which may not be cleared after a failing system
suspend.
Fix this issue by adding "complete" PM callbacks to intel-hid and
intel-vbtn to clear the wakeup_mode flag and the "wakeup mask" bit
of the EC GPE if they have not been cleared earlier.

Previously, asus-wmi was using the AGFN interface and FAN_CTRL device
for CPU fan control. However, this code has been found to be not fully
working on some recent products, and having checked the spec, these
interfaces are marked as being removed from future products currently
in development.
The replacement appears to be the CPU_FAN device, added in spec version
8.3 (March 2014) and present on many modern Asus laptops.
Add support for this device, and use it whenever it is detected.
The older approach based on AGFN and FAN_CTRL is used as a fallback
on products that do not have such device.
Other than switching between automatic and full speed, there is
no fan speed control through this new interface.

The asus-wmi driver currently uses the "AGFN" interface and
the FAN_CTRL device for fan control. According to the spec, this
interface is very dated and marked as pending removal from products
currently in development.
Clean up the way that the AGFN fan is detected and handled, also
preparing the driver for the introduction of an alternate fan
control method needed to support recent Asus products.
Not anticipating further development of this interface, simplify
the code by dropping any notion of being able to control multiple
AGFN fans (this was already limited to just a single fan through only
exposing a single fan in sysfs).
Check for the presence of AGFN fans at probe time, simplifying the code
flow in asus_hwmon_sysfs_is_visible().

The EC GPE needs to be set up for system wakeup only if there is a
driver depending on it, either intel-hid or intel-vbtn, bound to a
button device that is expected to wake up the system from sleep (such
as the power button on some Dell systems, like the XPS13 9360). It
doesn't need to be set up for waking up the system from sleep in any
other cases and whether or not it is expected to wake up the system
from sleep doesn't depend on whether or not the LPS0 device is
present in the ACPI namespace.
For this reason, rearrange the ACPI suspend-to-idle code to make the
drivers depending on the EC GPE wakeup take care of setting it up and
decouple that from the LPS0 device handling.
While at it, make intel-hid and intel-vbtn prepare for system wakeup
only if they are allowed to wake up the system from sleep by user
space (via sysfs).
[Note that acpi_ec_mark_gpe_for_wake() and acpi_ec_set_gpe_wake_mask()
are there to prevent the EC GPE from being disabled by the
acpi_enable_all_wakeup_gpes() call in acpi_s2idle_prepare(), so on
systems with either intel-hid or intel-vbtn this change doesn't
affect any interactions with the hardware or platform firmware.]

The Asus WMI spec indicates that the function being controlled here
is called "Fan Boost Mode". The user-facing documentation also calls it
this.
The spec uses the term "fan mode" is used to refer to other things,
including functionality expected to appear on future products.
We missed this before as we are not dealing with the most readable of
specs, and didn't forsee any confusion around shortening the name.
Rename "fan mode" to "fan boost mode" to improve consistency with the
spec and to avoid a future naming conflict.
There is no interface breakage here since this has yet to be included
in an official kernel release. I also updated the kernel version listed
under ABI accordingly.

Pull x86 platform driver updates from Andy Shevchenko:
"Gathered a bunch of x86 platform driver changes. It's rather big,
since includes two big refactors and completely new driver:
- ASUS WMI driver got a big refactoring in order to support the TUF
Gaming laptops. Besides that, the regression with backlight being
permanently off on various EeePC laptops has been fixed.
- Accelerometer on HP ProBook 450 G0 shows wrong measurements due to
X axis being inverted. This has been fixed.
- Intel PMC core driver has been extended to be ACPI enumerated if
the DSDT provides device with _HID "INT33A1". This allows to
convert the driver to be pure platform and support new hardware
purely based on ACPI DSDT.
- From now on the Intel Speed Select Technology is supported thru a
corresponding driver. This driver provides an access to the
features of the ISST, such as Performance Profile, Core Power, Base
frequency and Turbo Frequency.
- Mellanox platform drivers has been refactored and now extended to
support more systems, including new coming ones.
- The OLPC XO-1.75 platform is now supported.
- CB4063 Beckhoff Automation board is using PMC clocks, provided via
pmc_atom driver, for ethernet controllers in a way that they can't
be managed by the clock driver. The quirk has been extended to
cover this case.
- Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile
the information of Chuwi Hi10 Air has been fixed to cover more
models based on the same platform.
- Xiaomi notebooks have WMI interface enabled. Thus, the driver to
support it has been provided. It required some extension of the
generic WMI library, which allows to propagate opaque context to
the ->probe() of the individual drivers.
This release includes debugfs clean up from Greg KH for several
drivers that drop return code check and make debugfs absence or
failure non-fatal.
Also miscellaneous fixes here and there, mostly for Acer WMI and
various Intel drivers"

Most modern platforms already have the ACPI device "INT33A1" that could
be used to attach to the driver. Switch the driver to using that and
thus make the intel_pmc_core.c a pure platform_driver.
Some of the legacy platforms though, may still not have this ACPI device
in their ACPI tables. Thus for such platforms, move the code to manually
instantiate a platform_device into a new file of its own. This would
instantiate the intel_pmc_core platform device and thus attach to
the driver, if the ACPI device for the same ("INT33A1") is not present
in a system where it should be. This was discussed here:

Refer to the Intel SDM Vol.4, the package C-state residency counters
of modern IA micro-architecture are all ticking in TSC frequency,
hence we can apply simple math to transform the ticks into microseconds.
i.e.,
residency (ms) = count / tsc_khz
residency (us) = count / tsc_khz * 1000
This also aligns to other sysfs debug entries of residency counter in
the same metric in microseconds, benefits reading and scripting.

Modify DMI matching order: perform matching based on DMI_BOARD_NAME
before matching based on DMI_BOARD_VENDOR and DMI_PRODUCT_NAME in order
to reduce the number of ‘dmi_table’ entries necessary for new systems
support and keep matching order in logical way.
For example, the existing check for DMI_PRODUCT_NAME with prefixes
“MSN27", “MSN24”, "MSB” matches systems MSN2700-BXXXX, MSN2700-XXXX,
MSN2410-BXXXX, MSB7800-XXXX, where ‘XXXX’ specifies some systems
hardware flavors.
At the same time these systems also matched by DMI_BOARD_NAME
“VMOD0001”, because they all have the same platform configuration (LED,
interrupt control, mux etcetera).
New systems with different platform configuration, but with similar
DMI_PRODUCT_NAME MSN2700-2XXXX, MSN2700-2XXXX, MSB7800-2XXXX are about
to be added. These system have similar DMI_PRODUCT_NAME, since they
have same ports configuration as their predecessors. All new systems
will be matched by DMI_BOARD_NAME “VMOD0008”.
With the change provided in the patch it is enough just to add
“VMOD0008” match following natural after “VMOD0007”, otherwise
“VMOD0008” or all “MSN2700-2XXXX”, “MSN2700-2XXXX”, “MSB7800-2XXXX”
should be added on top of ‘mlxplat_dmi_table” in order to be matched
before “MSN27", “MSN24”, "MSB”.

Commands which causes PUNIT writes, store them and restore them on system

the latest mailbox request parameters. On resume these commands mail box
commands are executed again. There are only 5 such mail box commands which
will trigger such processing so a very low overhead in store and execute
on resume. Also there is no order requirement for mail box commands for

There are two per CPU data needs to be stored and cached to avoid repeated
MSR readings for accessing them later:
- Physical to logical CPU conversion
The PUNIT uses a different CPU numbering scheme which is not APIC id based.
So we need to establish relationship between PUNIT CPU number and Linux
logical CPU numbering which is based on APIC id. There is an MSR 0x53
(MSR_THREAD_ID), which gets physical CPU number for the local CPU where it
is read. Also the CPU mask in some messages will inform which CPUs needs
to be online/offline for a TDP level. During TDP switch if user offlined
some CPUs, then the physical CPU mask can't be converted as we can't
read MSR on an offlined CPU to go to a lower TDP level by onlining more
CPUs. So the mapping needs to be established at the boot up time.
- Bus number corresponding to a CPU
A group of CPUs are in a control of a PUNIT. The PUNIT device is exported
as PCI device. To do operation on a PUNIT for a CPU, we need to find out
to which PCI device it is related to. This is done by reading MSR 0x128
(MSR_CPU_BUS_NUMBER).
So during CPU online stages the above MSRs are read and stored. Later
this stored information is used to process IOCTLs request from the user
space.

Encapsulate common functions which all Intel Speed Select Technology
interface drivers can use. This creates API to register misc device for
user kernel communication and handle all common IOCTLs. As part of the
registry it allows a callback which is to handle domain specific ioctl
processing.
There can be multiple drivers register for services, which can be built
as modules. So this driver handle contention during registry and as well
as during removal. Once user space opened the misc device, the registered
driver will be prevented from removal. Also once misc device is opened by
the user space new client driver can't register, till the misc device is
closed.
There are two types of client drivers, one to handle mail box interface
and the other is to allow direct read/write to some specific MMIO space.
This common driver implements IOCTL ISST_IF_GET_PLATFORM_INFO.

The WMI exposes a write-only device ID where up to three fan modes can be
switched on some laptops (TUF Gaming FX505GM). There is a hotkey
combination Fn-F5 that does have a fan icon, which is designed to toggle
between fan modes. The DSTS of the device ID returns information about the
presence of this capability and the presence of each of the two additional
fan modes as a bitmask (0x01 - overboost present, 0x02 - silent present)
[1].
Add a SysFS entry that reads the last written value and updates value in
WMI on write and a hotkey handler that toggles the modes taking into
account their availability according to DSTS.
Modes:
* 0x00 - normal or balanced,
* 0x01 - overboost, increased fan RPM,
* 0x02 - silent, decreased fan RPM

Event codes are expected to be retrieved from a queue on at least some
models. Specifically, very likely the ACPI WMI devices with _UID ATK are
queued whereas those with ASUSWMI are not [1].
The WMI event codes are pushed into a circular buffer queue. After the INIT
method is called, ACPI code is allowed to push events into this buffer.
The INIT method cannot be reverted. If the module is unloaded and an event
(such as hotkey press) gets emitted before inserting it back the events get
processed delayed by one or if the queue overflows, additionally delayed by
about 3 seconds.
It might be considered a minor issue and no normal user would likely
observe this (there is little reason unloading the driver), but it does
significantly frustrate a developer who is unlucky enough to encounter
this. Therefore, the fallback to unqueued behavior occurs whenever
something unexpected happens.
The fix flushes the old key codes out of the queue on load. After receiving
event the queue is read until either ..FFFF or 1 is encountered. Also as
noted in [1] it is checked whether notify code is equal to 0xFF before
enabling queue processing in WMI notify handler.
DSDT examples:
FX505GM
Device (ATKD)
{ ..
Name (ATKQ, Package (0x10)
{
0xFFFFFFFF, ..
}
Method (IANQ, 1, Serialized)
{
If ((AQNO >= 0x10))

If (AQNO)
{
...
Local0 = DerefOf (ATKQ [AQHI])
AQHI++

Return (Local0)
}
Return (One)
}
This code is almost identical to K54C, which does return Ones on empty
queue.

The DSTS method detection mistakenly selects DCTS instead of DSTS if
nothing is returned when the method ID is not defined in WMNB. As a result,
the control of keyboard backlight is not functional for TUF Gaming series
laptops. Implement detection based on _UID of the WMI device instead.
There is evidence that DCTS is handled by ACPI WMI devices that have _UID
ASUSWMI, whereas none of the devices without ASUSWMI respond to DCTS and
DSTS is used instead [1].
DSDT examples:
FX505GM (_UID ATK):
Method (WMNB, 3, Serialized)

Add a new function to acpi.h / wmi.c that returns _UID of the ACPI WMI
device. For example, it returns "ATK" for the following declaration in
DSDT:
Device (ATKD)
{
Name (_HID, "PNP0C14" /* Windows Management Instrumentation Device */)
// _HID: Hardware ID
Name (_UID, "ATK") // _UID: Unique ID
..
Generally, it is possible that multiple PNP0C14 ACPI devices are present in
the system as mentioned in the commit message of commit bff431e49f
("ACPI: WMI: Add ACPI-WMI mapping driver").
Therefore the _UID is returned for a specific ACPI device that declares the
given GUID, to which it is also mapped by other methods of wmi module.

The asus-nb-wmi driver is matched by WMI alias but fails to load on TUF
Gaming series laptops producing multiple ACPI errors in the kernel log.
The input buffer for WMI method invocation size is 2 dwords, whereas
3 are expected by this model.
FX505GM:
..
Method (WMNB, 3, Serialized)
{
P8XH (Zero, 0x11)
CreateDWordField (Arg2, Zero, IIA0)
CreateDWordField (Arg2, 0x04, IIA1)
CreateDWordField (Arg2, 0x08, IIA2)
Local0 = (Arg1 & 0xFFFFFFFF)
...
Compare with older K54C:
...
Method (WMNB, 3, NotSerialized)
{
CreateDWordField (Arg2, 0x00, IIA0)
CreateDWordField (Arg2, 0x04, IIA1)
Local0 = (Arg1 & 0xFFFFFFFF)
...
Increase buffer size to 3 dwords. No negative consequences of this change
are expected, as the input buffer size is not verified. The original
function is replaced by a wrapper for a new method passing value 0 for the
last parameter. The new function will be used to control RGB keyboard

Dell platform team told us that some (DMI whitelisted) Dell Latitude
machines have ST microelectronics accelerometer at I2C address 0x29.
Presence of that ST microelectronics accelerometer is verified by existence
of SMO88xx ACPI device which represent that accelerometer. Unfortunately
ACPI device does not specify I2C address.
This patch registers lis3lv02d device for selected Dell Latitude machines
at I2C address 0x29 after detection. And for Dell Vostro V131 machine at
I2C address 0x1d which was manually detected.
Finally commit a7ae81952c ("i2c: i801: Allow ACPI SystemIO OpRegion to
conflict with PCI BAR") allowed to use i2c-i801 driver on Dell machines so
lis3lv02d correctly initialize accelerometer.
Tested on Dell Latitude E6440.

In ACPI, and now also in DT, the USB connectors usually have
their own device nodes. In case of USB Type-C, those
connector (port) nodes are child nodes of the controller or
PHY device, in our case the fusb302. The software fwnodes
allow us to create a similar child node for fusb302 that
represents the connector also on Intel CHT.
This makes it possible replace the fusb302 specific device
properties which were deprecated with the common USB
connector properties that tcpm.c is able to use directly.

Registering real device entries (struct device) for the mode
muxes as well as for the orientation switches.
The Type-C mux code was deliberately attempting to avoid
creation of separate device entries for the orientation
switch and the mode switch (alternate modes) because they
are not physical devices. They are functions of a single
physical multiplexer/demultiplexer switch device.
Unfortunately because of the dependency we still have on the
underlying mux device driver, we had to put in hacks like
the one in the commit 3e3b81965c ("usb: typec: mux: Take
care of driver module reference counting") to make sure the
driver does not disappear from underneath us. Even with
those hacks we were still left with a potential NUll pointer
dereference scenario, so just creating the device entries,
and letting the core take care of the dependencies. No more
hacks needed.

Some of latest ASUS laptops support new fn-lock mode switching.
This commit detect whether if the fn-lock option is enabled in
BIOS setting, and toggle the fn-lock mode via a new WMI DEVID
0x00100023 when the corresponding notify code captured.
The ASUS fn-lock mode switch is activated by pressing Fn+Esc.
When on, keys F1 to F12 behave as applicable, with meanings
defined by the application being used at the time. When off,
F1 to F12 directly triggers hardware features, well known audio
volume up/down, brightness up/down...etc, which were triggered
by holding down Fn key and F-keys.
Because there's no way to retrieve the fn-lock mode via existing
WMI methods per ASUS spec, driver need to initialize and keep the
fn-lock mode by itself.

When the ideapad-laptop driver was first written it was written for laptops
which had a hardware rfkill switch. So when the first ideapad laptops
showed up without a hw rfkill switch and it turned out that in this case
the ideapad firmware interface would always report the wifi being hardware-
blocked, a DMI id list of models which lack a hw rfkill switch was started
(by yours truly). Things were done this way to avoid regressing existing
models with a hw rfkill switch. In hindsight this was a mistake.
Lenovo releases a lot of ideapad models every year and even the latest
models still use the "VPC2004" ACPI interface the ideapad-laptop driver
binds to. Having a hw rfkill switch is quite rare on modern hardware, so
all these new models need to be added to the no_hw_rfkill_list, leading
to a never ending game of whack a mole.
Worse the failure mode when not present on the list, is very bad. In this
case the ideapad-laptop driver will report the wifi as being hw-blocked,
at which points NetworkManager does not even try to use it and the user
ends up with non working wifi.
This leads to various Linux fora on the internet being filled with
wifi not working on ideapad laptops stories, which does not make Linux
look good.
The failure mode when we flip the default to assuming that a hw rfkill
switch is not present OTOH is quite benign. When we properly report the
wifi as being hw-blocked on ideapads which do have the hw-switch; and it
is in the wifi-off position, then at least when using NetworkManager +
GNOME3 the user will get a "wifi disabled in hardware" message when trying
to connect to the wifi from the UI. If OTOH we assume there is no hardware
rfkill switch, then the user will get an empty list for the list of
available networks. Although the empty list vs the "wifi disabled in
hardware" message is a regression, it is a very minor regression and it
can easily be fixed on a model by model basis by filling the new
hw_rfkill_list this commit introduces.
Therefor this commit removes the ever growing no_hw_rfkill_list, flipping
the default to assuming there is no hw rfkill switch and adding a new
hw_rfkill_list. Thereby fixing the wifi not working on all the current
ideapad and yoga models which are not on the list yet and also fixing it
for all future ideapad and yoga models using the "VPC2004" ACPI interface.
Note once this patch has been accepted upstream. I plan to write a blog
post asking for users of ideapads and yoga's with a hw rfkill switch to
step forward, so that we can populate the new hw_rfkill_list with the few
older yoga and ideapad models which actually have a hw rfkill switch.

Add a module parameter which when enabled, will check on resume, if the
last S0ix attempt was successful. If not, the driver would warn and provide
helpful debug information (which gets latched during the failed suspend
attempt) to debug the S0ix failure.
This information is very useful to debug S0ix failures. Specially since
the latched debug information will be lost (over-written) if the system
attempts to go into runtime (or imminent) S0ix again after that failed
suspend attempt.

The intel_pmc_ipc driver has a placeholder for all possible resources
that may have been provided by ACPI. Since there are few optional ones,
the driver still uses them and binds to wrong ranges in resource tree:
# grep intel_punit_ipc /proc/iomem
00000000-00000000 : intel_punit_ipc
00000000-00000000 : intel_punit_ipc
00000000-00000000 : intel_punit_ipc
00000000-00000000 : intel_punit_ipc
This leads to issues with resource management during inserting and
removing modules, such as intel_pmc_ipc itself, which can't be inserted
anymore after first removal.
Count the actual resources provided and supply only them to the child device.
This is a real fix of the commit 8cc7fb4a65
("intel_pmc_ipc: update acpi resource structure for Punit")
that also fixes a symptoms described in the commit 6cc8cbbc88
("platform/x86: intel_punit_ipc: Fix resource ioremap warning")
that is going to be reverted afterwards.

Core changes:
- The big change this time around is the irqchip handling in
the qualcomm pin controllers, closely coupled with the
gpiochip. This rework, in a classic fall-between-the-chairs
fashion has been sidestepped for too long. The Qualcomm
IRQchips using the SPMI and SSBI transport mechanisms have
been rewritten to use hierarchical irqchip. This creates
the base from which I intend to gradually pull support for
hierarchical irqchips into the gpiolib irqchip helpers to
cut down on duplicate code. We have too many hacks in the
kernel because people have been working around the missing
hierarchical irqchip for years, and once it was there,
noone understood it for a while. We are now slowly adapting
to using it. This is why this pull requests include changes
to MFD, SPMI, IRQchip core and some ARM Device Trees
pertaining to the Qualcomm chip family. Since Qualcomm have
so many chips and such large deployments it is paramount
that this platform gets this right, and now it (hopefully)
does.
- Core support for pull-up and pull-down configuration, also
from the device tree. When a simple GPIO chip support a
"off or on" pull-up or pull-down resistor, we provide a
way to set this up using machine descriptors or device tree.
If more elaborate control of pull up/down (such as
resistance shunt setting) is required, drivers should be
phased over to use pin control. We do not yet provide a
userspace ABI for this pull up-down setting but I suspect
the makers are going to ask for it soon enough. PCA953x
is the first user of this new API.
- The GPIO mockup driver has been revamped after some
discussion improving the IRQ simulator in the process.
The idea is to make it possible to use the mockup for
both testing and virtual prototyping, e.g. when you do
not yet have a GPIO expander to play with but really
want to get something to develop code around before
hardware is available. It's neat. The blackbox testing
usecase is currently making its way into kernelci.
- ACPI GPIO core preserves non direction flags when updating
flags.
- A new device core helper for devm_platform_ioremap_resource()
is funneled through the GPIO tree with Greg's ACK.
New drivers:
- TQ-Systems QTMX86 GPIO controllers (using port-mapped
I/O)
- Gateworks PLD GPIO driver (vaccumed up from OpenWrt)
- AMD G-Series PCH (Platform Controller Hub) GPIO driver.
- Fintek F81804 & F81966 subvariants.
- PCA953x now supports NXP PCAL6416.
Driver improvements:
- IRQ support on the Nintendo Wii (Hollywood) GPIO.
- get_direction() support for the MVEBU driver.
- Set the right output level on SAMA5D2.
- Drop the unused irq trigger setting on the Spreadtrum
driver.
- Wakeup support for PCA953x.

On some platforms such as HP Elite-x2-1013-g3, the platform BIOS
enforces XTAL to remain off before S0ix state can be achieved. This may
not be optimum when we want to enable use cases like Low Power Audio,
Wake on Voice etc which always need 24mhz clock.
This introduces a new quirk to allow S0ix entry when all other
conditions except for XTAL clock are good on a given platform. The extra
power consumed by XTAL clock is about 2mw but it saves much more
platform power compared to the system that remains in just PC10.

This patch introduces a new debugfs entry to read current Package
cstate residency counters. A similar variant of this patch was discussed
earlier "https://patchwork.kernel.org/patch/9908563/" but didn't make it
into mainline for various reasons. Current version only adds debugfs
entry which is quite useful for S0ix debug but excludes the exported API
that was there in initial version. Though there are tools like turbostat
and socwatch which can also show this info but sometimes its more
practical to have it here as it's hard to switch between various tools for
S0ix debug when pmc_core driver is the primary debug tool. Internal and
external customers have requested for this patch to be included in the
PMC driver on many occasions and Google Chrome OS team has already included
it in their builds. This becomes handy when requesting logs from external
customers who may not always have above mentioned tools in their integrated
kernel builds.
Package cstate residency MSRs provide useful debug information about
system idle states. In idle states system must enter deeper Package
cstates. Package cstates depend not only on Core cstates but also on
various IP block's power gating status and LTR values.
For Intel Core SoCs Package C10 entry is a must for deeper sleep states
such as S0ix. "Suspend-to-idle" should ideally take this path:
PC0 -> PC10 -> S0ix. For S0ix debug, its logical to check for
Package C10 residency first if for some reason system fails to enter S0ix.
Please refer to this link for MSR details:

Icelake can resue most of the CNL PCH IPs as they are mostly similar.
This patch enables the PMC Core driver for ICL family.
It also addresses few other minor issues like upper case conversions and
some tab alignments.

The register (SLP_S0_RES) at offset slp_s0_offset is a 32 bit register.
The pmc_core_adjust_slp_s0_step() could overflow the u32 value while
returning it after adjusting the step. Thus change to u64, this is
already accounted for in debugfs attribute (that wants to output a
64 bit value).

In the function wmi_dev_match() the variable id is dereferenced without
first performing a NULL check. The variable can for example be NULL if
a WMI driver is registered without specifying the id_table field in
struct wmi_driver.
Add a NULL check and return that the driver can't handle the device if
the variable is NULL.

For some odd reason dell_rbu actually seems to want the physical and
not a bus address for the allocated buffer. Lets assume that actually
is correct given that it is BIOS-related and that is a good source
of insanity. In that case we should not use dma_alloc_coherent with
a NULL device to allocate memory, but use GFP_DMA32 to stay under
the 32-bit BIOS limit.

Commit ae7c8cba32 ("platform/x86: ideapad-laptop: add lenovo RESCUER
R720-15IKBN to no_hw_rfkill_list") added
DMI_MATCH(DMI_BOARD_NAME, "80WW")
for Lenovo RESCUER R720-15IKBN.
But DMI_BOARD_NAME does not match 80WW on Lenovo RESCUER R720-15IKBN,
thus cause Wireless LAN still be hard blocked.
On Lenovo RESCUER R720-15IKBN:
~$ cat /sys/class/dmi/id/sys_vendor
LENOVO
~$ cat /sys/class/dmi/id/board_name
Provence-5R3
~$ cat /sys/class/dmi/id/product_name
80WW
~$ cat /sys/class/dmi/id/product_version
Lenovo R720-15IKBN
So on Lenovo RESCUER R720-15IKBN:
DMI_SYS_VENDOR should match "LENOVO",
DMI_BOARD_NAME should match "Provence-5R3",
DMI_PRODUCT_NAME should match "80WW",
DMI_PRODUCT_VERSION should match "Lenovo R720-15IKBN".
Fix it, and in according with other entries in no_hw_rfkill_list,
use DMI_PRODUCT_VERSION instead of DMI_BOARD_NAME.

hid-asus depends on asus-wmi through the asus_wmi_evaluate_method. Before
this commit asus-wmi, and thus hid-asus, could not be loaded on non-Asus
systems. This breaks using Asus bluetooth keyboards such as the Asus
T100CHI keyboard with non Asus systems.
This commit fixes this by allowing asus-wmi to load on systems without the
Asus Management GUID.
This is safe to do since all asus-wmi sub drivers use
asus_wmi_register_driver which also checks for the GUID.
This commit also improves the error messages in asus_wmi_register_driver
to include "ASUS" in their description to make them more clear. This is
important since we now rely on those errors when loaded on systems without
the Asus Management GUID.

Recently introduced commit "platform/x86: intel_pmc_core: Show Latency
Tolerance info <51337cd94d18184601ac0fb4cf1a02b8bbabc3d7> skipped the
LTR from a reserved IP. Though this doesn't cause any functional issue
but it is needed for the consumers of "ltr_ignore" as the index printing
for "ltr_show" is missing. For example, w/o this change, a user that wants
to ignore LTR from ME would do something like
echo 5 > ltr_ignore
but the index for ME is 6. Printing a reserved IP helps to properly
calculate LTR ignore offsets.

used with both the port and the alternate modes, so on CHT

A previous commit "platform/x86: intel_pmc_core: Make the driver PCH
family agnostic <c977b98bbef5898ed3d30b08ea67622e9e82082a>" provided
better abstraction to this driver but has some fundamental issues.
e.g. the following condition
for (index = 0; index < pmcdev->map->ppfear_buckets &&
index < PPFEAR_MAX_NUM_ENTRIES; index++, iter++)
is wrong because for CNL, PPFEAR_MAX_NUM_ENTRIES is hardcoded as 5 which
is _wrong_ and even though ppfear_buckets is 8, the loop fails to read
all eight registers needed for CNL PCH i.e. PPFEAR0 and PPFEAR1. This
patch refactors the pfear show logic to correctly read PCH IP power
gating status for Cannonlake and beyond.

The Point of View TAB-P1006W-232-3G tablet has an ACPI firmware node with
a HID of BSG2150 describing the 2 Bosch sensors used in the device a
BMC150 compatible accelerometer and a BMC150 compatible magnetometer.
The ACPI firmware node actually contains 3 I2cSerialBusV2 resources,
but this seems to be a copy and paste job from the BSG1160 firmware node
on other devices, since there is no i2c-client listening to the 0x68
address listed in the third resource and the 0x68 address is identical
to the address of the third resource in the BSG1160 nodes, where as the
other 2 addresses are different.
Add the ID to the I2C multi instantiate list, so that the
i2c-multi-instantiate.c driver can handle it;
And add the necessary info to the i2c-multi-instantiate.c driver to
enumerate all I2C slaves correctly.
