[PATCH v6 0/5] Add GPU for RK356x SoCs

Hi all,

This series aims to bring the GPU support for the RK356x mainline. In
conjunction with the VOP2/HDMI TX patches v4 [0]) it has been tested
successfully on a RK3568 EVB1 with weston and glmark2-es2-wayland.

It should be noted that on the RK3568 EVB1 the supply of the GPU power
domain needs to be set to "always-on" in the device tree. There is an
ongoing discussion to provide a clean solution [1], in the meantime one
has to apply a hack.

Looking forward to your comments!

Best regards,
Michael

v6:
- use existing clock name "gpu" instead of "core"
- fix missing space in indentation

v5:
- address Rob's comments, describe clocks in SoC specific region
- move gpu_opp_table so that nodes without a reg are sorted alphabetically
- add GPU support to the RK3568 EVB1
