Overall the DSI and the board design is almost identical to Renesas r8a779g0 and white-hawk board. Signed-off-by: Tomi Valkeinen --- Changes in v3: - Update "Write DPTSR only if there are more than one crtc" patch to "Write DPTSR only if the second source exists" - Add Laurent's Rb - Link to v2: https://lore.kernel.org/r/20241205-rcar-gh-dsi-v2-0-42471851df86@ideasonboard.com Changes in v2: - Add the DT binding with a new conditional block, so that we can set only the port@0 as required - Drop port@1 from r8a779h0.dtsi (there's no port@1) - Add a new patch to write DPTSR only if num_crtcs > 1 - Drop RCAR_DU_FEATURE_NO_DPTSR (not needed anymore) - Add Cc: stable to the fix, and move it as first patch - Added the tags from reviews - Link to v1: https://lore.kernel.org/r/20241203-rcar-gh-dsi-v1-0-738ae1a95d2a@ideasonboard.com --- Tomi Valkeinen (10): drm/rcar-du: dsi: Fix PHY lock bit check drm/rcar-du: Write DPTSR only if the second source exists dt-bindings: display: bridge: renesas,dsi-csi2-tx: Add r8a779h0 dt-bindings: display: renesas,du: Add r8a779h0 clk: renesas: r8a779h0: Add display clocks drm/rcar-du: dsi: Add r8a779h0 support drm/rcar-du: Add support for r8a779h0 arm64: dts: renesas: gray-hawk-single: Fix indentation arm64: dts: renesas: r8a779h0: Add display support arm64: dts: renesas: gray-hawk-single: Add DisplayPort support .../display/bridge/renesas,dsi-csi2-tx.yaml | 1 + .../devicetree/bindings/display/renesas,du.yaml | 52 ++++++++- .../boot/dts/renesas/r8a779h0-gray-hawk-single.dts | 119 ++++++++++++++++++--- arch/arm64/boot/dts/renesas/r8a779h0.dtsi | 73 +++++++++++++ drivers/clk/renesas/r8a779h0-cpg-mssr.c | 4 + drivers/gpu/drm/renesas/rcar-du/rcar_du_drv.c | 18 ++++ drivers/gpu/drm/renesas/rcar-du/rcar_du_group.c | 24 +++-- drivers/gpu/drm/renesas/rcar-du/rcar_mipi_dsi.c | 4 +- .../gpu/drm/renesas/rcar-du/rcar_mipi_dsi_regs.h | 1 - 9 files changed, 272 insertions(+), 24 deletions(-) --- base-commit: adc218676eef25575469234709c2d87185ca223a change-id: 20241008-rcar-gh-dsi-9c01f5deeac8 Best regards,
