Fix some existing bugs that prevent the driver from working properly and adapt the platform-specific code to support the UMS9230 SoC.
Signed-off-by: Otto Pflüger <otto.pflue...@abscue.de> --- Changes in v2: - Fix device tree binding syntax - Use more descriptive clock names - Keep IOMMU handle in DPU node and make the driver handle this instead (otherwise the binding turns out to be incorrect for newer hardware) - Remove all accesses to IOMMU registers from the DPU driver (after observing that sharkl3 can also use sprd_iommu, I concluded that they should not be needed at all) - Fix container_of macros in sprd_dsi.h - Link to v1: https://lore.kernel.org/r/20250719-ums9230-drm-v1-0-e4344a05e...@abscue.de --- Otto Pflüger (15): dt-bindings: display: sprd: adapt for UMS9230 support dt-bindings: display: sprd: add memory-region property dt-bindings: display: sprd: allow attaching a DSI panel drm: of: try binding port parent node instead of the port itself drm: sprd: remove plane and crtc destroy callbacks drm: sprd: register a DSI bridge and move init code to pre_enable drm: sprd: add support for UMS9230 DSI PLL drm: sprd: fix DSI rate and PLL setup code drm: sprd: select REGMAP in Kconfig drm: sprd: add clock gating support drm: sprd: add support for newer DPU versions drm: sprd: always initialize DPU and DSI registers drm: sprd: do not access IOMMU registers drm: sprd: implement IOMMU-based buffer management drm: sprd: add fbdev support .../bindings/display/sprd/sprd,sharkl3-dpu.yaml | 32 +- .../display/sprd/sprd,sharkl3-dsi-host.yaml | 42 ++- drivers/gpu/drm/drm_of.c | 2 +- drivers/gpu/drm/sprd/Kconfig | 3 + drivers/gpu/drm/sprd/Makefile | 3 +- drivers/gpu/drm/sprd/megacores_pll.c | 28 +- drivers/gpu/drm/sprd/sprd_dpu.c | 62 ++-- drivers/gpu/drm/sprd/sprd_dpu.h | 1 + drivers/gpu/drm/sprd/sprd_drm.c | 57 +++- drivers/gpu/drm/sprd/sprd_drm.h | 10 + drivers/gpu/drm/sprd/sprd_dsi.c | 181 +++++++---- drivers/gpu/drm/sprd/sprd_dsi.h | 19 +- drivers/gpu/drm/sprd/sprd_gem.c | 343 +++++++++++++++++++++ drivers/gpu/drm/sprd/sprd_gem.h | 34 ++ 14 files changed, 697 insertions(+), 120 deletions(-) --- base-commit: 05adbee3ad528100ab0285c15c91100e19e10138 change-id: 20250719-ums9230-drm-eb271289bfcd prerequisite-message-id: <20250720123003.37662-3-krzysztof.kozlow...@linaro.org> prerequisite-patch-id: da2f2d2034f4b3fd5ffea122a6d0df20cb68fb88 prerequisite-patch-id: 2ccbc6b30bb53f303470b2a8376df4356e8785a3 Best regards, -- Otto Pflüger <otto.pflue...@abscue.de>
