[PATCH v4 00/27] drm/rockchip: RK356x VOP2 support

[Sascha Hauer]

This is v4 of adding RK356x VOP2 support. Due to popular demand I added
a changelog to each patch, at least starting with changes to v3, I
didn't care to add the older changes as well. I hopefully integrated all
feedback I received to v3. Additionally I added some patches to the HDMI
driver to support resolutions up to 4k at 60Hz. The patches are mostly
taken from the downstream kernel. Some have been send to public lists,
but were never applied upstream for reasons I do not know. The patches
are a bit more intrusive than needed for my case, but are present in the
downstream kernel for a long time, so I decided just to take them
instead of stripping them down to my needs. With these patches I
successfully used the driver with 4k at 30Hz. 4k at 60Hz doesn't work for me,
I hope this is due to my low quality cable.

Changes since v3:
- added changelog to each patch
- Add 4k support to hdmi driver
- rebase on v5.17-rc1

Changes since v2:
- Add pin names to HDMI supply pin description
- Add hclk support to HDMI driver
- Dual license rockchip-vop2 binding, update binding
- Add HDMI connector to board dts files
- drop unnecessary gamma_lut registers from vop2
- Update dclk_vop[012] clock handling, no longer hacks needed
- Complete regmap conversion

Changes since v1:
- drop all unnecessary waiting for frames within atomic modeset and plane update
- Cluster subwin support removed
- gamma support removed
- unnecessary irq_lock removed
- interrupt handling simplified
- simplified zpos handling
- drop is_alpha_support(), use fb->format->has_alpha instead
- use devm_regulator_get() rather than devm_regulator_get_optional() for hdmi regulators
- Use fixed number of planes per video port
- Drop homegrown regmap code from vop2 driver (not complete yet)
- Add separate include file for vop2 driver to not pollute the vop include
