[PATCH v9 00/23] drm/rockchip: RK356x VOP2 support

This is v9 of the VOP2 series. Biggest change this time is that I marked
the hclk_vo as critical instead of enabling it in the HDMI driver. Also
a little bugfix is included for a bug in setting up the layer mixer,
reported by Andy Yan.

Note that this series depends on these patches:

clk: rk3568: Add CLK_SET_RATE_PARENT to the HDMI reference clock
clk: rk3568: drop CLK_SET_RATE_PARENT from dclk_vop*
clk: rockchip: rk3568: Add more PLL rates

These are not included in this series as they are already applied by
Heiko. They haven't hit mainline yet, you can pick them from v4 of this
series.

Changes since v8:
- make hclk_vo a critical clock instead of enabling it in the hdmi driver
- Fix vop2_setup_layer_mixer(), reported by Andy Yan
- Limit planes possible_crtcs to actually existing crtcs
- simplify vop2_create_crtc() a bit

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
