The Infineon PEB2466 codec is a programmable DSP-based four channels
codec with filters capabilities.
It also provides signals as GPIOs.
The WCD9340 audio codec appears on Slimbus twice: as IFD device without
properties and the actual audio-codec referencing the former via
wcd9340_ifd. Allow in the binding both versions to fix several warnings
like:
sdm850-samsung-w737.dtb: ifd@0,0: 'reset-gpios' is a required property
sdm850-samsung-w737.dtb: ifd@0,0: 'slim-ifc-dev' is a required property
sdm850-samsung-w737.dtb: ifd@0,0: 'interrupt-controller' is a required property

The new Broadcom Broadband BCMBCA SoCs includes a updated HSSPI
controller. Add new compatible strings to differentiate the old and new
controller while keeping MIPS based chip with the old compatible. Update
property requirements for these two revisions of the controller. Also
add myself and Kursad as the maintainers.

The goodix i2c-hid bindings currently support two models of
touchscreen: GT7375P and GT7986U. The datasheets of both touchscreens
show the following things:
* The mainboard that the touchscreen is connected to is only expected
to supply one voltage to the touchscreen: 3.3V.
* The touchscreen, depending on stuffing options, can accept IO to the
touchscreen as either 3.3V or 1.8V. Presumably this means that the
touchscreen has its own way internally to make or deal with 1.8V
signals when it's configured for 1.8V IO.
NOTE: you've got to look very carefully at the datasheet for the
touchscreen to see that the above bullets are true. Specifically, the
datasheet shows a signal called VDDIO and one might think that this is
where a mainboard would provide VDDIO to the touchscreen. Upon closer
inspection, however, a footnote can be found that says "When VDDIO is
left floating, the logic level is 1.8V [...]; when VDDIO is connected
to AVDD, the logic level is AVDD.". Thus the VDDIO pin on the
touchscreen IC is actually a selector and not a pin whre the mainboard
would pass a reference voltage.
The fact that the touchscreen isn't supplied 1.8V by the mainboard
means that when I originally submitted bindings for these touchscreens
I only listed the 3.3V rail in the bindings. It can be noted that the
original bindings and driver were added for sc7180-trogdor boards and
these boards all use 3.3V IO via a level shifter on the mainboard.
It turns out that with sc7280-herobrine-evoker, we've got a bit of a
strange monkey on our hands. Due to some very interesting but
(unfortunately) set-in-stone hardware design, we are doing 1.8V IO to
the touchscreen but we _also_ have some extra buffers on the mainboard
that need to be powered up to make the IO lines work. After much
pondering about this, it seems like the best way to handle this is to
add an optional "mainboard-vddio" rail to the bindings that is used to
power up the buffers. Specifically, the fact that the touchscreen
datasheet documents that its IOs can be at a different voltage level
than its main power rail means that there truly are two voltage rails
associated with the touchscreen, even if we don't actually provide the
IO rail to it. Thus it doesn't feel absurd for the DT node on the host
to have a 1.8V rail to power up anything related to its 1.8V logic.

AT91 device tree updates for 6.3 #2
It contains:
- cleanups arround flexcom nodes on SAM9X60 SoC as follows:
- preserve same ID for flexcoms and the embedded nodes (e.g. flx4
will embed uart4, spi4, i2c4 but not e.g. uart1, spi2, i2c3);
- SoC specific bindings were moved from board specific file to SoC
specific file
- DMA bindings for all flexcom nodes were added
- SoC file was filled with missing flexcom nodes
- new SAM9X60 Curiosity board that contains 1 uSDcard interface, 1 SDcard
interface, 1 USB device interface, 2 USB Type-A interfaces, 2 CAN
interfaces, 1 10/100 Ethernet interface, 1 LCD RGB666 interface,
1 Gb DDR2, 4 Gb NAND Flash, 2Kb EEPROM, leds, button, power
regulators, UART and JTAG connectors

The GPU clock controller bindings for the Qualcomm sm8350 platform are
not correct. The driver uses .fw_name instead of using indices to bind
parent clocks, thus demanding the clock-names usage. With the proper
clock-names in place, the bindings becomes equal to the bindings defined
by qcom,gpucc.yaml, so it is impractical to keep them in a separate
file.

Convert the bindings of the Freescale Pixel Pipeline to YAML.
The conversion drops the previously listed compatibles for several SoCs.
It is unclear, if the PXP on these SoCs is compatible to any of the PXPs
on the existing SoCs and would allow to reuse the already defined
compatibles. The missing compatibles should be brought back when the
support for the PXP on these SoCs is added.
