Subject: [PATCH v2 0/3] drm: rockchip: vop2: Add VP clock resets support

The clock reset must be used when the VOP is configured. Skipping it can
put the VOP in an unknown state where the HDMI signal is either lost or
not matching the selected mode.

This adds support for rk3588(s) based SoCs.

Changes since v1:
- Add AXI and AHB clock resets
- Set maxItems for !rk3588 in vop2 bindings

Detlev Casanova (3):
  vop2: Add clock resets support
  arm64: dts: rockchip: Add VOP clock resets for rk3588s
  dt-bindings: display: vop2: Add VP clock resets
