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@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@30Hz. 4k@60Hz doesn't work for me, I hope this is due to my low quality cable. Sascha 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 Andy Yan (1): drm: rockchip: Add VOP2 driver Benjamin Gaignard (1): dt-bindings: display: rockchip: dw-hdmi: Add compatible for rk3568 HDMI Douglas Anderson (2): drm/rockchip: dw_hdmi: Use auto-generated tables drm/rockchip: dw_hdmi: Set cur_ctr to 0 always Michael Riesch (1): arm64: dts: rockchip: enable vop2 and hdmi tx on quartz64a Nickey Yang (1): drm/rockchip: dw_hdmi: add default 594Mhz clk for 4K@60hz Sascha Hauer (21): drm/encoder: Add of_graph port to struct drm_encoder drm/rockchip: dw_hdmi: Do not leave clock enabled in error case drm/rockchip: dw_hdmi: rename vpll clock to reference clock drm/rockchip: dw_hdmi: add rk3568 support drm/rockchip: dw_hdmi: add regulator support drm/rockchip: dw_hdmi: Add support for hclk drm/rockchip: dw_hdmi: drop mode_valid hook clk: rockchip: rk3568: Add more PLL rates dt-bindings: display: rockchip: dw-hdmi: Make unwedge pinctrl optional dt-bindings: display: rockchip: dw-hdmi: use "ref" as clock name dt-bindings: display: rockchip: dw-hdmi: Add regulator support dt-bindings: display: rockchip: dw-hdmi: Add additional clock dt-bindings: display: rockchip: Add binding for VOP2 arm64: dts: rockchip: rk3399: reorder hmdi clocks arm64: dts: rockchip: rk3399: rename HDMI ref clock to 'ref' arm64: dts: rockchip: rk356x: Add VOP2 nodes arm64: dts: rockchip: rk356x: Add HDMI nodes arm64: dts: rockchip: rk3568-evb: Enable VOP2 and hdmi clk: rk3568: drop CLK_SET_RATE_PARENT from dclk_vop* clk: rk3568: Add CLK_SET_RATE_PARENT to the HDMI reference clock drm/rockchip: Make VOP driver optional .../display/rockchip/rockchip,dw-hdmi.yaml | 29 +- .../display/rockchip/rockchip-vop2.yaml | 146 + arch/arm64/boot/dts/rockchip/rk3399.dtsi | 6 +- .../boot/dts/rockchip/rk3566-quartz64-a.dts | 48 + arch/arm64/boot/dts/rockchip/rk3566.dtsi | 4 + .../boot/dts/rockchip/rk3568-evb1-v10.dts | 48 + arch/arm64/boot/dts/rockchip/rk3568.dtsi | 4 + arch/arm64/boot/dts/rockchip/rk356x.dtsi | 86 + drivers/clk/rockchip/clk-rk3568.c | 14 +- drivers/gpu/drm/rockchip/Kconfig | 14 + drivers/gpu/drm/rockchip/Makefile | 4 +- drivers/gpu/drm/rockchip/dw_hdmi-rockchip.c | 293 +- drivers/gpu/drm/rockchip/rockchip_drm_drv.c | 3 +- drivers/gpu/drm/rockchip/rockchip_drm_drv.h | 7 +- drivers/gpu/drm/rockchip/rockchip_drm_fb.c | 2 + drivers/gpu/drm/rockchip/rockchip_drm_vop.h | 15 + drivers/gpu/drm/rockchip/rockchip_drm_vop2.c | 2665 +++++++++++++++++ drivers/gpu/drm/rockchip/rockchip_drm_vop2.h | 480 +++ drivers/gpu/drm/rockchip/rockchip_vop2_reg.c | 285 ++ include/drm/drm_encoder.h | 2 + include/dt-bindings/soc/rockchip,vop2.h | 14 + 21 files changed, 4039 insertions(+), 130 deletions(-) create mode 100644 Documentation/devicetree/bindings/display/rockchip/rockchip-vop2.yaml create mode 100644 drivers/gpu/drm/rockchip/rockchip_drm_vop2.c create mode 100644 drivers/gpu/drm/rockchip/rockchip_drm_vop2.h create mode 100644 drivers/gpu/drm/rockchip/rockchip_vop2_reg.c create mode 100644 include/dt-bindings/soc/rockchip,vop2.h -- 2.30.2
