[v10,00/24] drm/rockchip: RK356x VOP2 support

Message

Sascha Hauer April 8, 2022, 11:22 a.m. UTC

This is v10 finally. The series is rebased to v5.18-rc1 which means that
it no longer depends on the clk patches, but there are new dependencies:

drm/rockchip: Refactor IOMMU initialisation (https://lists.freedesktop.org/archives/dri-devel/2022-April/349548.html)
arm64: dts: rockchip: add basic dts for the radxa rock3 model a

The latter is only necessary for adding VOP2 support for that board. It should
be in Heikos tree already.

Highlight in this series is that it now works properly on a RK3566. Also
z-ordering of the planes is fixed.

Sascha

Changes since v9:
- rebase on v5.18-rc1
- Do not register windows which don't have its own framebuffer on RK3566
- fix mixed up register writes in vop2_setup_dly_for_windows()
- move call to rockchip_drm_dma_attach_device() from vop2_bind() to vop2_enable()
- Fix zpos handling

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
