Subject: [PATCH 0/5] arm64: dts: rockchip: pinmux fixes and support for 2
 adapters for Theobroma boards

This is based on top of
https://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip.git/log/?h=v6.15-armsoc/dts64
6ee0b9ad3995 ("arm64: dts: rockchip: Add rng node to RK3588") as it
depends on the (merged) series from
https://lore.kernel.org/all/20250211-pre-ict-jaguar-v6-0-4484b0f88cfc@cherry.de/

Patches for Haikou Video Demo adapter for PX30 Ringneck and RK3399 Puma
(patches 4 and 5) also depend on the following patch series:
https://lore.kernel.org/linux-devicetree/20250220-pca976x-reset-driver-v1-0-6abbf043050e@cherry.de/

This fixes incorrect pinmux on UART0 and UART5 for PX30 Ringneck on
Haikou.

This adds support for the HAIKOU-LVDS-9904379 adapter for PX30 Ringneck
fitted on a Haikou carrierboard.

Additionally, this adds support for Haikou Video Demo adapter on PX30
Ringneck and RK3399 Puma fitted on a Haikou carrierboard. Notably
missing from the overlay is the OV5675 camera module which expects
19.2MHz which we cannot exactly feed right now. Modifications to the
OV5675 drivers will be made so it's more flexible and then support for
the camera module will be added. This adapter has a 720x1280 DSI display
with a GT911 touchscreen, a GPIO-controllable LED and an I2C GPIO
expander. Support for this adapter on RK3588 Tiger is being added in a
separate patch series[1].

Note that the DSI panel currently is glitchy on both PX30 Ringneck and
RK3399 Puma but this is being tackled in another series[2]. Since this
will not be fixed through DT properties for the panel, adding the DT
nodes for the DSI panel even if not perfect right now seems acceptable
to me.
