[PATCH v2 0/3] arm64: dts: rockchip: add and enable DSI2 on rk3588

[Heiko Stuebner]

This adds the dcphy and dsi2 controller nodes and adds an overlay
for the Tiger-Haikou Video-Demo adapter that provides a DSI display.

changes in v2:
- adapt to changed dcphy binding (phy-cells = 1)
- tiger-overlay changes (Quentin):
  - drop forgotten hdmi-connector node
  - improve description
  - fix node sorting
  - drop unnecessary pwm-pinctrl (set in tiger.dtsi)

Heiko Stuebner (3):
  arm64: dts: rockchip: add mipi dcphy nodes to rk3588
  arm64: dts: rockchip: add dsi controller nodes on rk3588
  arm64: dts: rockchip: add overlay for tiger-haikou video-demo adapter

[PATCH v2 1/3] arm64: dts: rockchip: add mipi dcphy nodes to rk3588

[Heiko Stuebner]

From: Heiko Stuebner <heiko.stuebner@cherry.de>

Add the two MIPI-DC-phy nodes to the RK3588, that will be used by the
DSI2 controllers and hopefully in some future also for camera input.

[PATCH v2 3/3] arm64: dts: rockchip: add overlay for tiger-haikou video-demo adapter

[Heiko Stuebner]

From: Heiko Stuebner <heiko.stuebner@cherry.de>

This adds support for the video-demo-adapter DEVKIT ADDON CAM-TS-A01
(https://embedded.cherry.de/product/development-kit/) for the Haikou
devkit with Tiger RK3588 SoM.

The Video Demo adapter is an adapter connected to the fake PCIe slot
labeled "Video Connector" on the Haikou devkit.

It's main feature is a Leadtek DSI-display with touchscreen and a camera
(that is not supported yet). To drive these components a number of
additional regulators are grouped on the adapter as well as a PCA9670
gpio-expander to provide the needed additional gpio-lines.

We have three additional regulators for the cameras, I think it'd make 
sense to define those as well even if there's no camera stack on RK3588 
for now?

Our downstream has a pinctrl for that too.

C.f. 
https://git.theobroma-systems.com/tiger-linux.git/tree/arch/arm64/boot/dts/rockchip/rk3588-tiger-haikou-video-demo.dts#n185 
and 
https://git.theobroma-systems.com/tiger-linux.git/tree/arch/arm64/boot/dts/rockchip/rk3588-tiger-haikou-video-demo.dts#n259. 
I think this would be enough to guarantee the PCA9670 is not held in 
reset due to leftover debug sessions in the bootloader.

Can you please also rebase on top of 
https://lore.kernel.org/linux-rockchip/20250131-pre-ict-jaguar-v4-0-c971e2852e8d@cherry.de/T/#m7481695caf708c13edc662293d01fa372123532f 
where we add overlay application tests at build time?

Cheers,
Quentin
