0ec7f158dc platform/x86: int3472: Add support for GPIO type 0x02 (IR flood LED)
Add support for GPIO type 0x02, which controls an IR flood LED used
for face authentication on some laptops (e.g. Dell Pro Max 16 Premium).

Without this patch, the kernel logs "GPIO type 0x02 unknown; the sensor
may not work" and IR sensors paired with a flood LED cannot function.

The flood LED is registered through the LED subsystem like the existing
privacy LED, including a lookup entry to allow future consumer drivers
to find and control it via led_get().

To support multiple LEDs per INT3472 device, convert the single led
struct member to an array with a counter.

218d3c44f5 platform/x86: int3472: Parameterize LED con_id in registration
Add a con_id parameter to skl_int3472_register_led() to allow callers
to specify both the LED name suffix and lookup con_id instead of
hardcoding "privacy". This prepares for registering additional LED
types with different names.

While at it, rename the privacy LED's GPIO con_id from "privacy-led"
to "privacy" in int3472_get_con_id_and_polarity() and pass it
directly to skl_int3472_register_led(), reducing churn when adding
new LED types.

No functional change.

2a7b7652b1 platform/x86: int3472: Handle GPIO type 0x10 (DOVDD)
The Lenovo ThinkPad X1 Fold 16 Gen 1 has an OV5675 sensor (ACPI HID
OVTI5675) behind an INT3472 discrete PMIC controller. The INT3472
_DSM returns GPIO type 0x10 for one of the pins, which controls the
DOVDD (digital I/O power) regulator enable.

Type 0x10 is not currently handled by the driver, causing the GPIO to
be ignored with a warning. Add INT3472_GPIO_TYPE_DOVDD (0x10) and
handle it as a regulator with con_id "dovdd" to match the supply name

9db327083f ASoC: ti: davinci-mcasp: Add asynchronous mode support
McASP has dedicated clock & frame sync registers for both transmit
and receive. Currently McASP driver only supports synchronous behavior and
couples both TX & RX settings.

Add logic that enables asynchronous mode via ti,async-mode property. In
async mode, playback & record can be done simultaneously with different
audio configurations (tdm slots, tdm width, audio bit depth).

Note the ability to have different tx/rx DSP formats (i2s, dsp_a, etc.),
while possible in hardware, remains to be a gap as it require changes
to the corresponding machine driver interface.

Existing IIS (sync mode) and DIT mode logic remains mostly unchanged.
Exceptions are IIS mode logic that previously assumed sync mode, which has
now been made aware of the distinction. And shared logic across all modes
also now checks for McASP tx/rx-specific driver attributes. Those
attributes have been populated according to the original extent, ensuring
no divergence in functionality.

Constraints no longer applicable for async mode are skipped.
Clock selection options have also been added to include rx/tx-only clk_ids,
exposing independent configuration via the machine driver as well.

Note that asynchronous mode is not applicable for McASP in DIT mode,
which is a transmitter-only mode to interface w/ self-clocking formats.

d095d2dbcc MIPS: copy pic32.h header file from asm/mach-pic32/ to include/platform-data/
There are currently some pic32 MIPS drivers that are in tree, and are
only configured to be compiled on the pic32 platform. There's a risk of
breaking some of these drivers when migrating drivers away from legacy
APIs. It happened to me with a pic32 clk driver.

Let's go ahead and copy the MIPS pic32.h header to
include/linux/platform_data/, and make a minor update to allow compiling
this on other architectures. This will make it easier, and cleaner to
enable COMPILE_TEST for some of these pic32 drivers.

The asm variant of the header file will be dropped once all drivers have
been updated.

'calibrate' was a one-shot event sent to the sensor to calibrate itself.
It is used on Bosch sensors (BMI160, BMA254).
Light sensors work differently: They are first put in calibration mode,
tests are run to collect information and calculate the calibration
values to apply. Once done, the sensors are put back in normal mode.

Accept boolean true and false (not just true) to enter/exit calibration
state.

Check "echo 0 > calibrate" is supported.

7525566abd platform/x86: asus-wmi: add keyboard brightness event handler
The keyboard brightness control of Asus WMI keyboards is handled in
kernel, which leads to the shortcut going from brightness 0, to 1,
to 2, and 3.

However, for HID keyboards it is exposed as a key and handled by the
user's desktop environment. For the toggle button, this means that
brightness control becomes on/off. In addition, in the absence of a
DE, the keyboard brightness does not work.

Therefore, expose an event handler for the keyboard brightness control
which can then be used by hid-asus. Since this handler is called from
an interrupt context, defer the actual work to a workqueue.

In the process, introduce ASUS_EV_MAX_BRIGHTNESS to hold the constant
for maximum brightness since it is shared between hid-asus/asus-wmi.

Some devices, such as the Z13 have multiple Aura devices connected
to them by USB. In addition, they might have a WMI interface for
RGB. In Windows, Armoury Crate exposes a unified brightness slider
for all of them, with 3 brightness levels.

Therefore, to be synergistic in Linux, and support existing tooling
such as UPower, allow adding listeners to the RGB device of the WMI
interface. If WMI does not exist, lazy initialize the interface.

Since hid-asus and asus-wmi can both interact with the led objects
including from an atomic context, protect the brightness access with a
spinlock and update the values from a workqueue. Use this workqueue to
also process WMI keyboard events, so they are handled asynchronously.

b8460480f6 i3c: mipi-i3c-hci: Allow for Multi-Bus Instances
Add support for MIPI I3C Host Controllers with the Multi-Bus Instance
capability.  These controllers can host multiple I3C buses (up to 15)
within a single hardware function (e.g., PCIe B/D/F), providing one
indepedent HCI register set and corresponding I3C bus controller logic
per bus.

A separate platform device will represent each instance, but it is
necessary to allow for shared resources.

Multi-bus instances share the same MMIO address space, but the ranges are
not guaranteed to be contiguous. To avoid overlapping mappings, pass
base_regs from the parent mapping to child devices.

Allow the IRQ to be shared among instances.

fa5ef10561 Merge tag 'spi-v6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi updates from Mark Brown:
 "This release is almost entirely new drivers, with a couple of small
  changes in generic code.

  The biggest individual update is a rename of the existing Microchip
  driver and the addition of a new driver for the silicon SPI controller
  in their PolarFire SoCs. The overlap between the soft IP supported by
  the current driver and this new one is regrettably all in the IP and
  not in the register interface offered to software.

   - Add a time offset parameter for offloads, allowing them to be
     defined in relation to each other. This is useful for IIO type
     applcations where you trigger an operation then read the result
     after a delay.

   - Add a tracepoint for flash exec_ops, bringing the flash support
     more in line with the debuggability of vanilla SPI.

   - Support for Airoha EN7523, Arduino MCUs, Aspeed AST2700, Microchip
     PolarFire SPI controllers, NXP i.MX51 ECSPI target mode, Qualcomm
     IPQ5414 and IPQ5332, Renesas RZ/T2H, RZ/V2N and RZ/2NH and SpacemiT
     K1 QuadSPI.

  There's also a small set of ASoC cleanups that I mistakenly applied to
  the SPI tree and then put more stuff on top of before it was brought
  to my attention, sorry about that"

for the ACPI evaluation result but never frees it, causing a 192-byte
memory leak on each call.

39ae6c50e5 platform/x86: asus-armoury: add ppt_* and nv_* tuning knobs
Adds the ppt_* and nv_* tuning knobs that are available via WMI methods
and adds proper min/max levels plus defaults.

The min/max are defined by ASUS and typically gained by looking at what
they allow in the ASUS Armoury Crate application - ASUS does not share
the values outside of this. It could also be possible to gain the AMD
values by use of ryzenadj and testing for the minimum stable value.

The general rule of thumb for adding to the match table is that if the
model range has a single CPU used throughout, then the DMI match can
omit the last letter of the model number as this is the GPU model.

If a min or max value is not provided it is assumed that the particular
setting is not supported. for example ppt_pl2_sppt_min/max is not set.
If a <ppt_setting>_def is not set then the default is assumed to be
<ppt_setting>_max

It is assumed that at least AC settings are available so that the
firmware attributes will be created - if no DC table is available
and power is on DC, then reading the attributes is -ENODEV.
