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

v4: see https://lore.kernel.org/linux-rockchip/20211126151729.1026566-1-knaerzche@gmail.com/
v3: see https://lore.kernel.org/linux-rockchip/20210805025948.10900-1-ezequiel@collabora.com/

The Bifrost GPU in Rockchip RK356x SoCs has a core and a bus clock.
Reflect this in the SoC specific part of the binding.

Rockchip SoCs RK3566 and RK3568 have a Mali Gondul core
which is based on the Bifrost architecture. It has
one shader core and two execution engines.

Quoting the datasheet:

Mali-G52 1-Core-2EE
* Support 1600Mpix/s fill rate when 800MHz clock frequency
* Support 38.4GLOPs when 800MHz clock frequency

RK356x SoCs have a second thermal sensor for the GPU. This adds the
cooling map and trip points for it to make use of its contribution as
a cooling device.
