Hi,

This has been tested in combination with the series from Heiko Stübner
enabling DSI support for the RK3588 [0] (DSI controller support has been
merged already, only the PHY support is missing) on the RK3588 EVB1.

[0] https://lore.kernel.org/linux-rockchip/20241203164934.1500616-1-heiko@sntech.de/

Changes since PATCHv1:
 * https://lore.kernel.org/all/20241210164333.121253-1-sebastian.reichel@collabora.com/
 * move additionalProperties below required in the DT binding
 * collect Reviewed-by from Krzysztof Kozlowski, Andy Yan and Jessica Zhang
 * improve Kconfig help text

Thanks for having a look.

Greetings,

-- Sebastian

The Rockchip W552793DBA-V10 display/touchscreen board contains a
Wanchanglong W552793BAA panel, which in turn is using a Raydium
RM67200 MIPI-DSI controller. Add a DT binding for the DSI panel.

The Rockchip W552793DBA-V10 display/touchscreen board contains a
Wanchanglong W552793BAA panel, which in turn is using a Raydium
RM67200 MIPI-DSI controller. Add a DSI panel driver for it.

The W552793BAA panel init sequence has been taken from the RK3588
EVB1 vendor kernel devicetree.

So, this function will sleep for 30 msec and then for 60 more. Is that
