@Jianfeng: Did you encounter any particular issue with the current approach?

This patch is adding a dependency of hdptxphy1 to vop for all rk3588
boards, but not all rk3588 boards have dual hdmi, armsom sige7 is an
example. At runtime I will get errors because there is no hdptxphy1
enabled in devicetree:

[    2.945675] rockchip-drm display-subsystem: [drm] *ERROR* failed to get pll_hdmiphy1

Overwrting vop node at board level to remove the dependency of hdptxphy1
can fix the issue.

Best regards,
