Merge tag 'media/v5.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:

 - Media documentation is now split into admin-guide, driver-api and
   userspace-api books (a longstanding request from Jon);

 - The media Kconfig was reorganized, in order to make easier to select
   drivers and their dependencies;

 - The testing drivers now has a separate directory;

 - added a new driver for Rockchip Video Decoder IP;

 - The atomisp staging driver was resurrected. It is meant to work with
   4 generations of cameras on Atom-based laptops, tablets and cell
   phones. So, it seems worth investing time to cleanup this driver and
   making it in good shape.

 - Added some V4L2 core ancillary routines to help with h264 codecs;

 - Added an ov2740 image sensor driver;

 - The si2157 gained support for Analog TV, which, in turn, added
   support for some cx231xx and cx23885 boards to also support analog
   standards;

 - Added some V4L2 controls (V4L2_CID_CAMERA_ORIENTATION and
   V4L2_CID_CAMERA_SENSOR_ROTATION) to help identifying where the camera
   is located at the device;

 - VIDIOC_ENUM_FMT was extended to support MC-centric devices;

 - Lots of drivers improvements and cleanups.

 "Fixes and new features for pstore.

  This is a pretty big set of changes (relative to past pstore pulls),
  but it has been in -next for a while. The biggest change here is the
  ability to support a block device as a pstore backend, which has been
  desired for a while. A lot of additional fixes and refactorings are
  also included, mostly in support of the new features.

   - refactor pstore locking for safer module unloading (Kees Cook)

Chris Chiu 7b91f1565f platform/x86: asus_wmi: Reserve more space for struct bias_args
On the ASUS laptop UX325JA/UX425JA, most of the media keys are not
working due to the ASUS WMI driver fails to be loaded. The ACPI error
as follows leads to the failure of asus_wmi_evaluate_method.
  ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [IIA3] at bit offset/length 96/32 exceeds size of target Buffer (96 bits) (20200326/dsopcode-203)
  No Local Variables are initialized for Method [WMNB]
  ACPI Error: Aborting method \_SB.ATKD.WMNB due to previous error (AE_AML_BUFFER_LIMIT) (20200326/psparse-531)

The DSDT for the WMNB part shows that 5 DWORD required for local
variables and the 3rd variable IIA3 hit the buffer limit.

Method (WMNB, 3, Serialized)
{ ..
    CreateDWordField (Arg2, Zero, IIA0)
    CreateDWordField (Arg2, 0x04, IIA1)
    CreateDWordField (Arg2, 0x08, IIA2)
    CreateDWordField (Arg2, 0x0C, IIA3)
    CreateDWordField (Arg2, 0x10, IIA4)
    Local0 = (Arg1 & 0xFFFFFFFF)
    If ((Local0 == 0x54494E49))
  ..
}

The limitation is determined by the input acpi_buffer size passed
to the wmi_evaluate_method. Since the struct bios_args is the data
structure used as input buffer by default for all ASUS WMI calls,
the size needs to be expanded to fix the problem.

Hans de Goede cfae58ed68 platform/x86: intel-vbtn: Only blacklist SW_TABLET_MODE on the 9 / "Laptop" chasis-type
The HP Stream x360 11-p000nd no longer report SW_TABLET_MODE state / events
with recent kernels. This model reports a chassis-type of 10 / "Notebook"
which is not on the recently introduced chassis-type whitelist

Commit de9647efea ("platform/x86: intel-vbtn: Only activate tablet mode
switch on 2-in-1's") added a chassis-type whitelist and only listed 31 /
"Convertible" as being capable of generating valid SW_TABLET_MOD events.

Commit 1fac39fd03 ("platform/x86: intel-vbtn: Also handle tablet-mode
switch on "Detachable" and "Portable" chassis-types") extended the
whitelist with chassis-types 8 / "Portable" and 32 / "Detachable".

And now we need to exten the whitelist again with 10 / "Notebook"...

The issue original fixed by the whitelist is really a ACPI DSDT bug on
the Dell XPS 9360 where it has a VGBS which reports it is in tablet mode
even though it is not a 2-in-1 at all, but a regular laptop.

So since this is a workaround for a DSDT issue on that specific model,
instead of extending the whitelist over and over again, lets switch to
a blacklist and only blacklist the chassis-type of the model for which
the chassis-type check was added.

Note this also fixes the current version of the code no longer checking
if dmi_get_system_info(DMI_CHASSIS_TYPE) returns NULL.

Kees Cook 791205e3ec pstore/ram: Introduce max_reason and convert dump_oops
Now that pstore_register() can correctly pass max_reason to the kmesg
dump facility, introduce a new "max_reason" module parameter and
"max-reason" Device Tree field.

The "dump_oops" module parameter and "dump-oops" Device
Tree field are now considered deprecated, but are now automatically
converted to their corresponding max_reason values when present, though
the new max_reason setting has precedence.

For struct ramoops_platform_data, the "dump_oops" member is entirely
replaced by a new "max_reason" member, with the only existing user
updated in place.

Additionally remove the "reason" filter logic from ramoops_pstore_write(),
as that is not specifically needed anymore, though technically
this is a change in behavior for any ramoops users also setting the
printk.always_kmsg_dump boot param, which will cause ramoops to behave as
if max_reason was set to KMSG_DUMP_MAX.

Hans de Goede dd950f16b1 platform/x86: intel-vbtn: Detect switch position before registering the input-device
Setting the initial state of input-device switches must be done before
registering the input-device.

Otherwise the initial state will get send out as an event as soon
as input_sync() gets called.

E.g. when undocking a tablet using intel-vbtn to report SW_TABLET_MODE
and SW_DOCK before this commit we would get (evemu-record output):

E: 0.000001 0005 0005 0001	# EV_SW / SW_DOCK              1
E: 0.000001 0000 0000 0000	# ------------ SYN_REPORT (0) ---------- +0ms
E: 0.000109 0005 0005 0000	# EV_SW / SW_DOCK              0
E: 0.000109 0000 0000 0000	# ------------ SYN_REPORT (0) ---------- +0ms
E: 0.000133 0005 0001 0001	# EV_SW / SW_TABLET_MODE       1
E: 0.000133 0000 0000 0000	# ------------ SYN_REPORT (0) ---------- +0ms

The first SW_DOCK=1 report is spurious, setting the initial switch
state before registering the input-device fixes this.

Hans de Goede 10d7ff74b6 platform/x86: asus-wmi: Ignore WMI events with code 0x79
On some Asus devices, e.g. the T100TA, when the charger is connected
we not only get a WMI event with code 0x58, but immediately after that
event we also get an even with code 0x79.

This is likely related to these devices having an Asus WMI device with a
device-id of 0x00120066, which seems to provide some sort of charger-type
info. The T100TA charger over a micro-USB connector, the embedded-
controller register read when calling asus_wmi_get_devstate(0x00120066)
returns different values when connected to a USB port (max 500mA charging)
vs when connected to a 2A capable wall-charger. But the AML code reading
this mangles the return value so that we can no longer tell the difference.
So for now the meaning of the value return when getting the status of
device-id 0x00120066 is unclear.

This commit adds a key-mapping of code 0x79 to KE_IGNORE, silencing the
kernel logging the following message every time the charger is plugged-in:

Hans de Goede aab9e7896e platform/x86: asus-nb-wmi: Revert "Do not load on Asus T100TA and T200TA"
The WMI INIT method on for some reason turns on the camera LED on these
2-in-1s, without the WMI interface allowing further control over the LED.

To fix this commit b5f7311d3a ("platform/x86: asus-nb-wmi: Do not load
on Asus T100TA and T200TA") added a blacklist with these 2 models on it
since the WMI driver did not add any extra functionality to these models.

Recently I've been working on making more 2-in-1 models report their
tablet-mode (SW_TABLET_MODE) to userspace; and I've found that these 2
Asus models report this through WMI. This commit reverts the adding
of the blacklist, so that the Asus WMI driver can be used on these
models to report their tablet-mode.

Note, not calling INIT is also not an option, because then we will not
receive events when the tablet-mode changes. So the LED issue will need
to be fixed somewhere else entirely.

Commit de9647efea ("platform/x86: intel-vbtn: Only activate tablet mode
switch on 2-in-1's") added a DMI chassis-type check to avoid accidentally
reporting SW_TABLET_MODE = 1 to userspace on laptops.

Some devices with a detachable keyboard and using the intel-vbnt (INT33D6)
interface to report if they are in tablet mode (keyboard detached) or not,
report 32 / "Detachable" as chassis-type, e.g. the HP Pavilion X2 series.

Other devices with a detachable keyboard and using the intel-vbnt (INT33D6)
interface to report SW_TABLET_MODE, report 8 / "Portable" as chassis-type.
The Dell Venue 11 Pro 7130 is an example of this.

Extend the DMI chassis-type check to also accept Portables and Detachables
so that the intel-vbtn driver will report SW_TABLET_MODE on these devices.

Note the chassis-type check was originally added to avoid a false-positive
tablet-mode report on the Dell XPS 9360 laptop. To the best of my knowledge
that laptop is using a chassis-type of 9 / "Laptop", so after this commit
we still ignore the tablet-switch for that chassis-type.

But if we are not getting the initial status of the switch because the

the presence of a tablet-mode switch to userspace at all, as userspace may
use the mere presence of this switch for certain heuristics.

Jithu Joseph 2d30fcdd43 platform/x86: Add Slim Bootloader firmware update signaling driver
Slim Bootloader(SBL) is a small open-source boot firmware,
designed for running on certain Intel platforms. SBL can be
thought-of as fulfilling the role of a minimal BIOS
implementation, i.e initializing the hardware and booting
Operating System.

Since SBL is not UEFI compliant, firmware update cannot be triggered
using standard UEFI runtime services. Further considering performance
impact, SBL doesn't look for a firmware update image on every reset
and does so only when firmware update signal is asserted.

SBL exposes an ACPI-WMI device which comes up in sysfs as
/sys/bus/wmi/44FADEB1xxx and this driver adds a
"firmware_update_request" device attribute. This attribute normally
has a value of 0 and userspace can signal SBL to update firmware,
on next reboot, by writing a value of 1 like:

echo 1 > /sys/bus/wmi/devices/44FADEB1xxx/firmware_update_request

This driver only implements a signaling mechanism, the actual firmware
update process and various details like firmware update image format,
firmware image location etc are defined by SBL and are not in the
scope of this driver.

Arnd Bergmann 3ce2db608e platform/x86: intel_pmc_core: avoid unused-function warnings
When both CONFIG_DEBUG_FS and CONFIG_PM_SLEEP are disabled, the
functions that got moved out of the #ifdef section now cause
a warning:

drivers/platform/x86/intel_pmc_core.c:654:13: error: 'pmc_core_lpm_display' defined but not used [-Werror=unused-function]
  654 | static void pmc_core_lpm_display(struct pmc_dev *pmcdev, struct device *dev,
      |             ^~~~~~~~~~~~~~~~~~~~
drivers/platform/x86/intel_pmc_core.c:617:13: error: 'pmc_core_slps0_display' defined but not used [-Werror=unused-function]
  617 | static void pmc_core_slps0_display(struct pmc_dev *pmcdev, struct device *dev,
      |             ^~~~~~~~~~~~~~~~~~~~~~

Rather than add even more #ifdefs here, remove them entirely and
let the compiler work it out, it can actually get rid of all the
debugfs calls without problems as long as the struct member is
there.

The two PM functions just need a __maybe_unused annotations to avoid
another warning instead of the #ifdef.

Intel Elkhart Lake exposes SCU/PMC as an ACPI device that only supports
IPC functionality so add a platform driver supporting it. Interrupt is
optional so we let intel_scu_ipc_probe() to decide based on the passed
platform data whether it uses interrupt or polling.
