The CANFD on RZ/{G2L,G3E} and R-Car Gen4 support 3 modes FD-Only mode,
Classical CAN mode and CAN-FD mode. In FD-Only mode, communication in
Classical CAN frame format is disabled. Document renesas,fd-only to handle
this mode. As these SoCs support 3 modes, update the description of
renesas,no-can-fd property and disallow it for R-Car Gen3.

- Update ADMA device tree bindings for tegra264 to support up to 64
interrupt channels by setting 'interrupts' property maxItems to 64.
- Also, update the 'allOf' conditional schema to ensure correct maxItems
for 'interrupts' based on compatible string, including tegra210 (22)
and tegra186 (32) ADMA controllers.

Pull sound fixes from Takashi Iwai:
"This became a bit larger than wished for, often seen as a bump at the
middle, but almost all changes are small device-specific fixes, so the
risk must be pretty low.
- SoundWire fix for missing symbol export
- Fixes for device-tree bindings
- A fix for OOB access in USB-audio, spotted by fuzzer
- Quirks for HD-audio, SoundWire, AMD ACP
- A series of ASoC tlv320 and wsa codec fixes

vsprintf.c uses a mix of the `kernel.kptr_restrict` sysctl and the

The driver binding documentation (still) mentions that "When a driver is
attached to a device, the device is inserted into the driver's list of
devices.".
While it is true that the driver-core keeps track of all the devices
that are attached to a driver, this is purely for internal purposes
(i.e. it is an implementation detail) and has no relevance for user
facing documentation.
In fact, it is even misleading, since it could be read as if it were
valid for driver implementations to keep track of all the devices bound
to it.
Instead, drivers operate on a per-device basis, with a separate
per-device instance created when the driver is bound to a device.
Hence, remove the mention of a driver's list of devices and instead add
some documentation of the relationship between drivers and devices.

Add "adi,low-cmode-impedance" boolean property which, when present,
configures the PHY for the lowest common-mode impedance on the receive
pair for 100BASE-TX operation by clearing the B_100_ZPTM_EN_DIMRX bit.
This is suited for capacitive coupled applications and other
applications where there may be a path for high common-mode noise to
reach the PHY.
If this value is not present, the value of the bit by default is 1,
which is normal termination (zero-power termination) mode.

RGMU a.k.a Reduced Graphics Management Unit is a small state machine
with the sole purpose of providing IFPC (Inter Frame Power Collapse)
support. Compared to GMU, it doesn't manage GPU clock, voltage
scaling, bw voting or any other functionalities. All it does is detect
an idle GPU and toggle the GDSC switch. As it doesn't access DDR space,
it doesn't require iommu.
So far, only Adreno 612 GPU has an RGMU core. Document it in

A612 GPU has a new IP called RGMU (Reduced Graphics Management Unit)
which replaces GMU. But it doesn't do clock or voltage scaling. So we
need the gpu core clock in the GPU node along with the power domain to
do clock and voltage scaling from the kernel. Update the bindings to
describe this GPU.

JSON Schema conditionals can become complex and error-prone when combined
with regex patterns. To improve readability and maintainability, replace
nested if-else blocks with a flattened structure using explicit enums.

Since it was never possible to use a non-PAGE_SIZE-aligned @source_addr,
go ahead and document this as a requirement. This is in preparation for
enforcing page-aligned @source_addr for all architectures in
guest_memfd.

In the past, KVM_SEV_SNP_LAUNCH_UPDATE accepted a non-page-aligned
'uaddr' parameter to copy data from, but continuing to support this with
new functionality like in-place conversion and hugepages in the pipeline
has proven to be more trouble than it is worth, since there are no known
users that have been identified who use a non-page-aligned 'uaddr'
parameter.
Rather than locking guest_memfd into continuing to support this, go
ahead and document page-alignment as a requirement and begin enforcing
this in the handling function.

Both clocks and clock-names are missing (a lot of) entries: add
all the used audio clocks and their description and also fix the

In commit f48b5e8bc2e1 ("dt-bindings: gpio-mmio: Add compatible string
for opencores,gpio") we marked opencores,gpio to be allowed with
brcm,bcm6345-gpio. This was wrong, opencores,gpio is not compatible with
brcm,bcm6345-gpio. It has a different register map and is 8-bit vs
Broadcom which is 32-bit. Change opencores,gpio to be a separate
compatible string for MMIO GPIO.
Also, as this change rewrote the entire enum, I took this opportunity to
alphabetically sort the list.
