CLOCK_PROTOCOL_ATTRIBUTES provides attributes to indicate the maximum
number of pending asynchronous clock rate changes supported by the
platform. If it's non-zero, then we should be able to use asynchronous
clock rate set for any clocks until the maximum limit is reached.
Tracking the current count of pending asynchronous clock set rate
requests, we can decide if the incoming/new request for clock set rate
can be handled asynchronously or not until the maximum limit is
reached.

Messages that are sent to platform, also known as commands and can be:
1. Synchronous commands that block the channel until the requested work
has been completed. The platform responds to these commands over the
same channel and hence can't be used to send another command until the
previous command has completed.
2. Asynchronous commands on the other hand, the platform schedules the
requested work to complete later in time and returns almost immediately
freeing the channel for new commands. The response indicates the success
or failure in the ability to schedule the requested work. When the work
has completed, the platform sends an additional delayed response message.
Using the same transmit buffer used for sending the asynchronous command
even for the delayed response corresponding to it simplifies handling of
the delayed response. It's the caller of asynchronous command that is
responsible for allocating the completion flag that scmi driver can
complete to indicate the arrival of delayed response.

Currently we pre-allocate transmit buffers only and use the first free
slot in that pre-allocated buffer for transmitting any new message that
are generally originated from OS to the platform firmware.
Notifications or the delayed responses on the other hand are originated
from the platform firmware and consumes by the OS. It's better to have
separate and dedicated pre-allocated buffers to handle the notifications.
We can still use the transmit buffers for the delayed responses.
In addition, let's prepare existing scmi_xfer_{get,put} for acquiring
and releasing a slot to identify the right(tx/rx) buffers.

let's consolidate setting up of both the channels under the function

failure of setting one up is not considered fatal.

The transmit(Tx) channels are specified as the first entry and the

Sometimes platfom may take too long to respond to the command and OS
might timeout before platform transfer the ownership of the shared
memory region to the OS with the response.
Since the mailbox channel associated with the channel is freed and new
commands are dispatch on the same channel, OS needs to wait until it
gets back the ownership. If not, either OS may end up overwriting the
platform response for the last command(which is fine as OS timed out
that command) or platform might overwrite the payload for the next
command with the response for the old.
The latter is problematic as platform may end up interpretting the
response as the payload. In order to avoid such race, let's wait until
the OS gets back the ownership before we prepare the shared memory with
the payload for the next command.

scmi_xfer_get_init ensures both transmit and receive buffer lengths are
within the maximum limits. If receive buffer length is not supplied by
the caller, it's set to the maximum limit value. Receive buffer length
is never modified after that. So there's no need for the extra check
when receive transmit completion for a command essage.
Further, if the response header length is greater than the prescribed
receive buffer length, the response buffer is truncated to the latter.

Current PSCI code handles idle state entry through the
psci_cpu_suspend_enter() API, that takes an idle state index as a
parameter and convert the index into a previously initialized
power_state parameter before calling the PSCI.CPU_SUSPEND() with it.
This is unwieldly, since it forces the PSCI firmware layer to keep track
of power_state parameter for every idle state so that the
index->power_state conversion can be made in the PSCI firmware layer
instead of the CPUidle driver implementations.
Move the power_state handling out of drivers/firmware/psci
into the respective ACPI/DT PSCI CPUidle backends and convert
the psci_cpu_suspend_enter() API to get the power_state
parameter as input, which makes it closer to its firmware
interface PSCI.CPU_SUSPEND() API.
A notable side effect is that the PSCI ACPI/DT CPUidle backends
now can directly handle (and if needed update) power_state
parameters before handing them over to the PSCI firmware
interface to trigger PSCI.CPU_SUSPEND() calls.

The PSCI checker currently relies on the generic ARM CPUidle
infrastructure to enter an idle state, which in turn creates
a dependency that is not really needed.
The PSCI checker code to test PSCI CPU suspend is built on
top of the CPUidle framework and can easily reuse the
struct cpuidle_state.enter() function (previously initialized
by an idle driver, with a PSCI back-end) to trigger an entry
into an idle state, decoupling the PSCI checker from the
generic ARM CPUidle infrastructure and simplyfing the code
in the process.
Convert the PSCI checker suspend entry function to use
the struct cpuidle_state.enter() function callback.

iscsi_ibft can use ACPI to find the iBFT entry during bootup,
currently, ISCSI_IBFT depends on ISCSI_IBFT_FIND which is
a X86 legacy way to find the iBFT by searching through the
low memory. This patch changes the dependency so that other
arch like ARM64 can use ISCSI_IBFT as long as the arch supports
ACPI.
ibft_init() needs to use the global variable ibft_addr declared
in iscsi_ibft_find.c. A #ifndef CONFIG_ISCSI_IBFT_FIND is needed
to declare the variable if CONFIG_ISCSI_IBFT_FIND is not selected.
Moving ibft_addr into the iscsi_ibft.c does not work because if
ISCSI_IBFT is selected as a module, the arch/x86/kernel/setup.c won't
be able to find the variable at compile time.

clk_get API that handles optional clks and an extra debugfs file that tells the
developer about the current parent of a clk.
The driver updates are dominated by i.MX in the diffstat, but that is mostly
because that SoC has started converting to the clk_hw style of clk
registration. The next big update is in the Amlogic meson clk driver that
gained some support for audio, cpu, and temperature clks while fixing some PLL
issues. Finally, the biggest thing that stands out is the conversion of a large
part of the Allwinner sunxi-ng driver to the new clk parent scheme that uses
less strings and more pointer comparisons to match clk parents and children up.
In general, it looks like we have a lot of little fixes and tweaks here and
there to clk data along with the normal addition of a handful of new drivers
and a couple new core framework features.

- Small frequency support for SiLabs Si544 chips
- Slow clk support for AT91 SAM9X60 SoCs
- Remove dead code in various clk drivers (-Wunused)
- Support for Marvell 98DX1135 SoCs
- Get duty cycle of generic pwm clks
- Improvement in mmc phase calculation and cleanup of some rate defintions
- Switch i.MX6 and i.MX7 clock drivers to clk_hw based APIs
- Add GPIO, SNVS and GIC clocks for i.MX8 drivers

mostly because that SoC has started converting to the clk_hw style of
clk registration. The next big update is in the Amlogic meson clk
driver that gained some support for audio, cpu, and temperature clks
while fixing some PLL issues. Finally, the biggest thing that stands
out is the conversion of a large part of the Allwinner sunxi-ng driver
to the new clk parent scheme that uses less strings and more pointer
comparisons to match clk parents and children up.
In general, it looks like we have a lot of little fixes and tweaks
here and there to clk data along with the normal addition of a handful
of new drivers and a couple new core framework features.
Core:
- Add a 'clk_parent' file in clk debugfs
- Add a clk_bulk_get_optional() API (with devm too)
New Drivers:
- Support gated clk controller on MIPS based BCM63XX SoCs
- Support SiLabs Si5341 and Si5340 chips
- Support for CPU clks on Raspberry Pi devices
- Audsys clock driver for MediaTek MT8516 SoCs
Updates:
- Convert a large portion of the Allwinner sunxi-ng driver to new clk parent scheme
- Small frequency support for SiLabs Si544 chips
- Slow clk support for AT91 SAM9X60 SoCs
- Remove dead code in various clk drivers (-Wunused)
- Support for Marvell 98DX1135 SoCs
- Get duty cycle of generic pwm clks
- Improvement in mmc phase calculation and cleanup of some rate defintions
- Switch i.MX6 and i.MX7 clock drivers to clk_hw based APIs
- Add GPIO, SNVS and GIC clocks for i.MX8 drivers
- Mark imx6sx/ul/ull/sll MMDC_P1_IPG and imx8mm DRAM_APB as critical clock
- Correct imx7ulp nic1_bus_clk and imx8mm audio_pll2_clk clock setting
- Add clks for new Exynos5422 Dynamic Memory Controller driver
- Clock definition for Exynos4412 Mali
- Add CMM (Color Management Module) clocks on Renesas R-Car H3, M3-N, E3, and D3
- Add TPU (Timer Pulse Unit / PWM) clocks on Renesas RZ/G2M
- Support for 32 bit clock IDs in TI's sci-clks for J721e SoCs
- TI clock probing done from DT by default instead of firmware
- Fix Amlogic Meson mpll fractional part and spread sprectrum issues
- Add Amlogic meson8 audio clocks
- Add Amlogic g12a temperature sensors clocks
- Add Amlogic g12a and g12b cpu clocks
- Add TPU (Timer Pulse Unit / PWM) clocks on Renesas R-Car H3, M3-W, and M3-N
- Add CMM (Color Management Module) clocks on Renesas R-Car M3-W
- Add Clock Domain support on Renesas RZ/N1"

Here is the "big" driver core and debugfs changes for 5.3-rc1
It's a lot of different patches, all across the tree due to some api
changes and lots of debugfs cleanups. Because of this, there is going
to be some merge issues with your tree at the moment, I'll follow up
with the expected resolutions to make it easier for you.
Other than the debugfs cleanups, in this set of changes we have:
- bus iteration function cleanups (will cause build warnings
with s390 and coresight drivers in your tree)
- scripts/get_abi.pl tool to display and parse Documentation/ABI
entries in a simple way
- cleanups to Documenatation/ABI/ entries to make them parse
easier due to typos and other minor things
- default_attrs use for some ktype users
- driver model documentation file conversions to .rst
- compressed firmware file loading
- deferred probe fixes
All of these have been in linux-next for a while, with a bunch of merge
issues that Stephen has been patient with me for. Other than the merge
issues, functionality is working properly in linux-next :)

"This contains two critical bug fixes and support for obtaining TPM
events triggered by ExitBootServices().
For the latter I have to give a quite verbose explanation not least
because I had to revisit all the details myself to remember what was
going on in Matthew's patches.
The preboot software stack maintains an event log that gets entries
every time something gets hashed to any of the PCR registers. What
gets hashed could be a component to be run or perhaps log of some
actions taken just to give couple of coarse examples. In general,
anything relevant for the boot process that the preboot software does
gets hashed and a log entry with a specific event type [1].
The main application for this is remote attestation and the reason why
it is useful is nicely put in the very first section of [1]:
"Attestation is used to provide information about the platform’s
state to a challenger. However, PCR contents are difficult to
interpret; therefore, attestation is typically more useful when
the PCR contents are accompanied by a measurement log. While not
trusted on their own, the measurement log contains a richer set of
information than do the PCR contents. The PCR contents are used to
provide the validation of the measurement log."
Because EFI_TCG2_PROTOCOL.GetEventLog() is not available after calling
ExitBootServices(), Linux EFI stub copies the event log to a custom
configuration table. Unfortunately, ExitBootServices() also generates
events and obviously these events do not get copied to that table.
Luckily firmware does this for us by providing a configuration table
identified by EFI_TCG2_FINAL_EVENTS_TABLE_GUID.
This essentially contains necessary changes to provide the full event
log for the use the user space that is concatenated from these two
partial event logs [2]"

This function can return a negative number when it fails, but res->sets

After the first call to GetEventLog() on UEFI systems using the TCG2
crypto agile log format, any further log events (other than those
triggered by ExitBootServices()) will be logged in both the main log and
also in the Final Events Log. While the kernel only calls GetEventLog()
immediately before ExitBootServices(), we can't control whether earlier
parts of the boot process have done so. This will result in log entries
that exist in both logs, and so the current approach of simply appending
the Final Event Log to the main log will result in events being
duplicated.
We can avoid this problem by looking at the size of the Final Event Log
just before we call ExitBootServices() and exporting this to the main
kernel. The kernel can then skip over all events that occured before
ExitBootServices() and only append events that were not also logged to
the main log.

Right now we only attempt to obtain the SHA1-only event log. The
protocol also supports a crypto agile log format, which contains digests
for all algorithms in use. Attempt to obtain this first, and fall back
to obtaining the older format if the system doesn't support it. This is
lightly complicated by the event sizes being variable (as we don't know
in advance which algorithms are in use), and the interface giving us
back a pointer to the start of the final entry rather than a pointer to
the end of the log - as a result, we need to parse the final entry to
figure out its length in order to know how much data to copy up to the
OS.

UEFI systems provide a boot services protocol for obtaining the TPM
event log, but this is unusable after ExitBootServices() is called.
Unfortunately ExitBootServices() itself triggers additional TPM events
that then can't be obtained using this protocol. The platform provides a
mechanism for the OS to obtain these events by recording them to a
separate UEFI configuration table which the OS can then map.
Unfortunately this table isn't self describing in terms of providing its
length, so we need to parse the events inside it to figure out how long
it is. Since the table isn't mapped at this point, we need to extend the
length calculation function to be able to map the event as it goes
along.

There is an arbitrary difference between the prototypes of
bus_find_device() and class_find_device() preventing their callers
from passing the same pair of data and match() arguments to both of
them, which is the const qualifier used in the prototype of
class_find_device(). If that qualifier is also used in the
bus_find_device() prototype, it will be possible to pass the same
match() callback function to both bus_find_device() and
class_find_device(), which will allow some optimizations to be made in
order to avoid code duplication going forward. Also with that, constify
the "data" parameter as it is passed as a const to the match function.
For this reason, change the prototype of bus_find_device() to match
the prototype of class_find_device() and adjust its callers to use the
const qualifier in accordance with the new prototype of it.

Replace the variable set function from "efivar_entry_set" to
"efivar_entry_set_safe" in efibc panic notifier.
In safe function parameter "block" will set to false
and will call "efivar_entry_set_nonblocking"to set efi variables.
efivar_entry_set_nonblocking is guaranteed to
not block and is suitable for calling from crash/panic handlers.
In UEFI android platform, when warm reset happens,
with this change, efibc will not block the reboot process.
Otherwise, set variable will call queue work and send to other offlined
cpus then cause another panic, finally will cause reboot failure.

Another round of SPDX updates for 5.2-rc6
Here is what I am guessing is going to be the last "big" SPDX update for
5.2. It contains all of the remaining GPLv2 and GPLv2+ updates that
were "easy" to determine by pattern matching. The ones after this are
going to be a bit more difficult and the people on the spdx list will be
discussing them on a case-by-case basis now.
Another 5000+ files are fixed up, so our overall totals are:
Files checked: 64545
Files with SPDX: 45529
Compared to the 5.1 kernel which was:
Files checked: 63848
Files with SPDX: 22576
This is a huge improvement.
Also, we deleted another 20000 lines of boilerplate license crud, always
nice to see in a diffstat.

The kbuild documentation clearly shows that the documents
there are written at different times: some use markdown,
some use their own peculiar logic to split sections.
Convert everything to ReST without affecting too much
the author's style and avoiding adding uneeded markups.
The conversion is actually:
- add blank lines and identation in order to identify paragraphs;
- fix tables markups;
- add some lists markups;
- mark literal blocks;
- adjust title markups.
At its new index.rst, let's add a :orphan: while this is not linked to

The system controller provides various services including the control

Future SoCs are going to have more than 255 device clocks in certain cases,
and thus the API must be extended to support this. The support is done in
backwards compatible extension, in which the new u32 clock identifier
fields are only used if the existing u8 size clock identifier is set as
255. In all the other cases, the existing u8 clock identifier is used. As
the size of the messages sent / received is not verified for existing
devices / old firmware, increasing the size of the messages from the end
is also fine. Due to this reason, depending on ABI version isn't necessary
either.

Signed-off-by: Sudeep Holla <sudeep.holla@arm.com>
The boolean rate_discrete needs to be assigned to clk->rate_discrete,
so that clock driver can distinguish between the continuous range and
discrete rates. It uses this in scmi_clk_round_rate could get the
rounded value if it's a continuous range.

As per the SCMI specification the bitfields for SENSOR_DESC attributes
are as follows:
attributes_low [7:0] Number of trip points supported
attributes_high [15:11] The power-of-10 multiplier in 2's-complement
format that is applied to the sensor units
Looks like the code developed during the draft versions of the
specification slipped through and are wrong with respect to final
released version. Fix them by adjusting the bitfields appropriately.

Starting with ACPI 6.2 bits 1 and 2 of the BGRT status field are no longer
reserved. These bits are now used to indicate if the image needs to be
rotated before being displayed.
The first device using these bits has now shown up (the GPD MicroPC) and
the reserved bits check causes us to reject the valid BGRT table on this
device.
Rather then changing the reserved bits check, allowing only the 2 new bits,
instead just completely remove it so that we do not end up with a similar
problem when more bits are added in the future.

"SoC updates, mostly refactorings and cleanups of old legacy platforms.
Major themes this release:
- Conversion of ixp4xx to a modern platform (drivers, DT, bindings)
- Moving some of the ep93xx headers around to get it closer to
multiplatform enabled.
- Cleanups of Davinci
This also contains a few patches that were queued up as fixes before
5.1 but I didn't get sent in before release"

Here is the "real" big set of char/misc driver patches for 5.2-rc1
Loads of different driver subsystem stuff in here, all over the places:
- thunderbolt driver updates
- habanalabs driver updates
- nvmem driver updates
- extcon driver updates
- intel_th driver updates
- mei driver updates
- coresight driver updates
- soundwire driver cleanups and updates
- fastrpc driver updates
- other minor driver updates
- chardev minor fixups
Feels like this tree is getting to be a dumping ground of "small driver
subsystems" these days. Which is fine with me, if it makes things
easier for those subsystem maintainers.
All of these have been in linux-next for a while with no reported
issues.

Each resource with in the device can be uniquely identified as defined
by TISCI. Since this is generic across the devices, resource allocation
also can be made generic instead of each client driver handling the
resource. So add helper apis to manage the resource.

TISCI provides support for getting the resources(IRQ, RING etc..)
assigned to a specific device. These resources can be handled by
the client and in turn sends TISCI cmd to configure the resources.
It is very important that client should keep track on usage of these
resources.
Add support for TISCI commands to get resource ranges.

TISCI has been updated to have support for Resource management(like
interrupts etc..). And there can be multiple device instances of a
resource type in a SoC. So every driver corresponding to a resource type
should get a TISCI handle so that it can make TISCI calls. And each
DT node corresponding to a device should exist under its corresponding
bus node as per the SoC architecture.
But existing apis in TISCI library assumes that all TISCI users are
child nodes of TISCI. Which is not true in the above case. So introduce

of_match_device can return NULL if no matching device is found though
it's highly unlikely to happen in scmi_probe as it's called only if
a valid match is found.
However we can use of_device_get_match_data() instead of
of_match_device()->data to handle NULL pointer checks and return -EINVAL

The Platform Coordinated mode, which is the default and mandatory

In some cases it's interesting for the user/developer to know if
the OSI mode is supported by the PSCI FW, so print a message to

The System Controller Firmware (SCFW) controls RTC, thermal
and WDOG etc., these resources' interrupt function are managed
by SCU. When any IRQ pending, SCU will notify Linux via MU general
interrupt channel #3, and Linux kernel needs to call SCU APIs
to get IRQ status and notify each module to handle the interrupt.
Since there is no data transmission for SCU IRQ notification, so
doorbell mode is used for this MU channel, and SCU driver will
use notifier mechanism to broadcast to every module which registers
the SCU block notifier.

It took me a while to understand what is going on in the nested
if-blocks.
Simplify it by removing unneeded code.
- if_changed automatically adds 'set -e', so any failure in the
series of commands makes it immediately fail as a whole.
So, the outer if block is entirely redundant.
- Since commit 9c2af1c737 ("kbuild: add .DELETE_ON_ERROR special target"),
GNU Make automatically deletes the target on any failure
in its recipe. The explicit 'rm -f $@' is redundant.
- Surrounding commands with ( ) will spawn a subshell to execute them
in it, but it is rarely useful to do so.

- Userspace wants to write a string with `len` bytes, not counting the
terminating NULL, so we should allocate `len+1` bytes. It looks like the
current code relied on having a nullbyte directly behind `kern_buff`,
which happens to work reliably as long as `len` isn't one of the kmalloc
size classes.
- strncpy_from_user() is completely wrong here; userspace is giving us a
(not necessarily null-terminated) buffer and its length.
strncpy_from_user() is for cases in which we don't know the length.
- Don't let broken userspace allocate arbitrarily big kmalloc allocations.
Just use memdup_user_nul(), which is designed precisely for things like

Here is the big driver core patchset for 5.1-rc1
More patches than "normal" here this merge window, due to some work in
the driver core by Alexander Duyck to rework the async probe
functionality to work better for a number of devices, and independant
work from Rafael for the device link functionality to make it work
"correctly".
Also in here is:
- lots of BUS_ATTR() removals, the macro is about to go away
- firmware test fixups
- ihex fixups and simplification
- component additions (also includes i915 patches)
- lots of minor coding style fixups and cleanups.
All of these have been in linux-next for a while with no reported
issues.

...
When checking a generic status block, we iterate over all the generic
data blocks. The loop condition only checks that the start of the
generic data block is valid (within estatus->data_length) but not the
whole block. Because the size of data blocks (excluding error data) may
vary depending on the revision and the revision is contained within the
data block, ensure that enough of the current data block is valid before
dereferencing any members otherwise an out-of-bounds access may occur if
estatus->data_length is invalid.
This relies on the fact that struct acpi_hest_generic_data_v300 is a
superset of the earlier version. Also rework the other checks to avoid
potential underflow.

The following commit:
a893ea15d764 ("tpm: move tpm_chip definition to include/linux/tpm.h")
introduced a build error when both IMA and EFI are enabled:
In file included from ../security/integrity/ima/ima_fs.c:30:
../security/integrity/ima/ima.h:176:7: error: redeclaration of enumerator "NONE"
What happens is that both headers (ima.h and efi.h) defines the same
'NONE' constant, and it broke when they started getting included from
the same file:
Rework to prefix the EFI enum with 'EFI_*'.
