[v8,00/24] drm/rockchip: RK356x VOP2 support

v8 is here. The only change this time is the renaming of hclk to niu.
The background is that I needed to add a new clock to the HDMI controller
driver to make it work on rk356x. The purpose of this clock was not
clear, but during v7 discussions it turned out that this clock is not
needed for the HDMI controller itself, but SoC internal logic demands
that this clock must be turned on whenever pclk_vo is turned on. This
logic is in the reference manual described as "NIU" (Native Interface
Unit), so I renamed the clock from hclk to niu.

Changes since v7:
- rename hclk to niu

Changes since v6:
- Move of_graph parsing out of runtime code to initialization

Changes since v5:
- Add new patch to fix dw-hdmi of_graph binding
- Drop "drm/encoder: Add of_graph port to struct drm_encoder" and solve
  issue internally in the driver
- make checkpatch cleaner

Changes since v4:
- Reorder patches in a way that binding/dts/driver patches are closer together
- Drop clk patches already applied by Heiko

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
