a=openpgp; fpr=C4380C3E965EFD81079FF3A7FA3DAA8CBC961EF5 Add everything needed to support the DSI output on Renesas r8a779h0 (V4M) SoC, and the DP output (via sn65dsi86 DSI to DP bridge) on the Renesas grey-hawk board. Overall the DSI and the board design is almost identical to Renesas r8a779g0 and white-hawk board. Note: the v4 no longer has the dts and the clk patches, as those have been merged to renesas-devel. Signed-off-by: Tomi Valkeinen --- Changes in v5: - Add minItems/maxItems to the top level cmms & vsps properties - Drop "minItems: 1" when not needed - Link to v4: https://lore.kernel.org/r/20241213-rcar-gh-dsi-v4-0-f8e41425207b@ideasonboard.com Changes in v4: - Dropped patches merged to renesas-devel - Added new patch "dt-bindings: display: renesas,du: Add missing maxItems" to fix the bindings - Add the missing maxItems to "dt-bindings: display: renesas,du: Add r8a779h0" - Link to v3: https://lore.kernel.org/r/20241206-rcar-gh-dsi-v3-0-d74c2166fa15@ideasonboard.com 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 (7): drm/rcar-du: dsi: Fix PHY lock bit check drm/rcar-du: Write DPTSR only if the second source exists dt-bindings: display: renesas,du: Add missing constraints dt-bindings: display: renesas,du: Add r8a779h0 dt-bindings: display: bridge: renesas,dsi-csi2-tx: Add r8a779h0 drm/rcar-du: dsi: Add r8a779h0 support drm/rcar-du: Add support for r8a779h0 .../display/bridge/renesas,dsi-csi2-tx.yaml | 1 + .../devicetree/bindings/display/renesas,du.yaml | 67 ++++++++++++++++++++-- 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 - 6 files changed, 102 insertions(+), 13 deletions(-) --- base-commit: adc218676eef25575469234709c2d87185ca223a change-id: 20241008-rcar-gh-dsi-9c01f5deeac8 Best regards,
