The display IPs in MediaTek SoCs support being interconnected with
different instances of DDP IPs (for example, merge0 or merge1) and/or
with different DDP IPs (for example, rdma can be connected with either
color, dpi, dsi, merge, etc), forming a full Display Data Path that
ends with an actual display.
The final display pipeline is effectively board specific, as it does
depend on the display that is attached to it, and eventually on the
sensors supported by the board (for example, Adaptive Ambient Light
would need an Ambient Light Sensor, otherwise it's pointless!), other
than the output type.
Add support for OF graphs to most of the MediaTek DDP (display) bindings
to add flexibility to build custom hardware paths, hence enabling board
specific configuration of the display pipeline and allowing to finally
migrate away from using hardcoded paths.
Please note that - while this commit retains retro-compatibility with
old device trees - it will break the ABI for mediatek,dsi and for
mediatek,dpi for the sake of consistency between the `ports` in all
MediaTek DRM drivers versus DRM bridge drivers as in the previous
binding, MediaTek was using `port` (implicitly, port@0) as an OUTPUT,
while now the first port is an INPUT, and the second one is an OUTPUT,
which is consistent with other DRM drivers which can be chained to
drm/mediatek.
As for maintainability concerns, I am aware that the old device tree
will not be actively tested anymore, but retrocompatibility breakages
will *not* be more likely to happen in the future because any addition
to the graph (new drivers) will be done only for features present on
newer SoCs, keeping the old ones (and their default pipeline) untouched.

There is one new SoC for each 32-bit Arm and 64-bit RISC-V, but both
the Rockchips rv1109 and Sopgho CV1812H are just minor variations of
already supported chips.
The other six new SoCs are all part of existing arm64 families, but
are somewhat more interesting:
- Samsung ExynosAutov920 is an automotive chip, and the first one
we support based on the Cortex-A78AE core with lockstep mode.
- Google gs101 (Tensor G1) is the chip used in a number of Pixel phones,
and is grouped with Samsung Exynos here since it is based on the same
SoC design, sharing most of its IP blocks with that series.
- MediaTek MT8188 is a new chip used for mid-range tablets and Chromebooks,
using two Cortex-A78 cores where the older MT8195 had four of them.
- Qualcomm SM8650 (Snapdragon 8 Gen 3) is their current top range
phone SoC and the first supported chip based on Cortex-X4, Cortex-A720
and Cortex-A520.
- Qualcomm X1E80100 (Snapdragon X Elite) in turn is the latest
Laptop chip using the custom Oryon cores.
- Unisoc UMS9620 (Tanggula 7 series) is a 5G phone SoC based on
Cortex-A76 and Cortex-A55
In terms of boards, we have
- Five old Microsoft Lumia phones, the HTC One Mini 2, Motorola Moto
G 4G, and Huawei Honor 5X/GR5, all based on Snapdragon SoCs.
- Multiple Rockchips mobile gaming systems (Anbernic RG351V,
Powkiddy RK2023, Powkiddy X55) along with the Sonoff iHost Smart
Home Hub and a few Rockchips SBCs
- Some ComXpress boards based on Marvell CN913x, which is the
follow-up to Armada 7xxx/8xxx.
- Six new industrial/embedded boards based on NXP i.MX8 and i.MX9
- Mediatek MT8183 based Chromebooks from Lenovo, Asus and Acer.
- Toradex Verdin AM62 Mallow carrier for TI AM62
- Huashan Pi board based on the SophGo CV1812H RISC-V chip
- Two boards based on Allwinner H616/H618
- A number of reference boards for various added SoCs from Qualcomm,
Mediatek, Google, Samsung, NXP and Spreadtrum
As usual, there are cleanups and warning fixes across all platforms as
well as added features for several of them.
