Pull devicetree updates from Rob Herring:
- Add Krzysztof Kozlowski as co-maintainer for DT bindings providing
much needed help.
- DT schema validation now takes DTB files as input rather than
intermediate YAML files. This decouples the validation from the
source level syntax information. There's a bunch of schema fixes as a
result of switching to DTB based validation which exposed some errors
and incomplete schemas and examples.
- Kbuild improvements to explicitly warn users running 'make
dt_binding_check' on missing yamllint
- Expand DT_SCHEMA_FILES kbuild variable to take just a partial
filename or path instead of the full path to 1 file.
- Convert various bindings to schema format: mscc,vsc7514-switch,
multiple GNSS bindings, ahci-platform, i2c-at91, multiple UFS
bindings, cortina,gemini-sata-bridge, cortina,gemini-ethernet, Atmel
SHA, Atmel TDES, Atmel AES, armv7m-systick, Samsung Exynos display
subsystem, nuvoton,npcm7xx-timer, samsung,s3c2410-i2c, zynqmp_dma,
msm/mdp4, rda,8810pl-uart
- New schemas for u-boot environment variable partition, TI clksel
- New compatible strings for Renesas RZ/V2L SoC
- Vendor prefixes for Xen, HPE, deprecated Synopsys, deprecated
HiSilicon
- Add/fix schemas for QEMU Arm 'virt' machine
- Drop unused of_alias_get_alias_list() function
- Add a script to check DT unittest EXPECT message output. Pass
messages also now print by default at PR_INFO level to help test
automation.

The datasheet lists the minimum Serial clock cycle (Write) as 66ns which is
15MHz. Mostly it can do much better than that and is in fact often run at
32MHz. With a clever driver that runs configuration commands at a low speed
and only the pixel data at the maximum speed the configuration can't be
messed up by transfer errors and the speed is only limited by the amount of
pixel glitches that one is able to tolerate.

Revert DPI support from binding.
DPI support relies on the bus-type enum which does not yet support
Mipi DPI, since no v4l2_fwnode_bus_type has been defined for this
bus type.
When DPI for anx7625 was initially added, it assumed that
V4L2_FWNODE_BUS_TYPE_PARALLEL was the correct bus type for
representing DPI, which it is not.
In order to prevent adding this mis-usage to the ABI, let's revert
the support.

In most cases, the default values of DSI PHY tuning registers should be
sufficient as they are fully optimized. However, in some cases where
extreme board parasitics cause the eye shape to degrade, the override
bits can be used to improve the signal quality.
The general guidelines for DSI PHY tuning include:
- High and moderate data rates may benefit from the drive strength and
drive level tuning.
- Drive strength tuning will affect the output impedance and may be used
for matching optimization.
- Drive level tuning will affect the output levels without affecting the
impedance.
The clock and data lanes have a calibration circuitry feature. The drive
strength tuning can be done by adjusting rescode offset for hstop/hsbot,
and the drive level tuning can be done by adjusting the LDO output level
for the HSTX drive.

The 'phandle-array' type is a bit ambiguous. It can be either just an
array of phandles or an array of phandles plus args. Many schemas for
phandle-array properties aren't clear in the schema which case applies
though the description usually describes it.
The array of phandles case boils down to needing:
items:
maxItems: 1
The phandle plus args cases should typically take this form:
items:
- items:
- description: A phandle
- description: 1st arg cell
- description: 2nd arg cell
With this change, some examples need updating so that the bracketing of
property values matches the schema.
