Hi Yifeng,

Add more compatible strings to:
Documentation/devicetree/bindings/mfd/syscon.yaml
Also add mfd maintainers and list to CC.

Compatible strings are supposed to be SOC related.

compatible = "rockchip,rk3568-pipe-phy-grf", "syscon";

Dump things with "#" down the list above status.

There are 2 resets. When the reset order does matter then use
devm_reset_control_array_get() to get the resets.
The use of reset-names is then not needed.
