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
used by sensor drivers (e.g. ov5675).
Also increase GPIO_SUPPLY_NAME_LENGTH from 5 to 6 to accommodate
the "dovdd" name (5 chars + null terminator).

- Support for Rock band 4 PS4 and PS5 guitars (Rosalie Wanders)
|

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Constraints no longer applicable for async mode are skipped.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.

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.

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.

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.

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"

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.

The fw_attributes_class provides a much cleaner interface to all of the
attributes introduced to asus-wmi. This patch moves all of these extra
attributes over to fw_attributes_class, and shifts the bulk of these
definitions to a new kernel module to reduce the clutter of asus-wmi
with the intention of deprecating the asus-wmi attributes in future.
The work applies only to WMI methods which don't have a clearly defined
place within the sysfs and as a result ended up lumped together in
/sys/devices/platform/asus-nb-wmi/ with no standard API.
Where possible the fw attrs now implement defaults, min, max, scalar,
choices, etc. As en example dgpu_disable becomes:
/sys/class/firmware-attributes/asus-armoury/attributes/dgpu_disable/
├── current_value
├── display_name
├── possible_values
└── type
as do other attributes.
