> ChangeList: > RFC v1: > 1. only upstream modeset and atomic at first commit. > 2. remove some unused code; > 3. use alpha and blend_mode properties; > 3. add yaml support; > 4. remove auto-adaptive panel driver; > 5. bugfix > > RFC v2: > 1. add sprd crtc and plane module for KMS, preparing for multi crtc&encoder > 2. remove gem drivers, use generic CMA handlers > 3. remove redundant "module_init", all the sub modules loading by KMS > > RFC v3: > 1. multi crtc&encoder design have problem, so rollback to v1 > > RFC v4: > 1. update to gcc-linaro-7.5.0 > 2. update to Linux 5.6-rc3 > 3. remove pm_runtime support > 4. add COMPILE_TEST, remove unused kconfig > 5. "drm_dev_put" on drm_unbind > 6. fix some naming convention issue > 7. remove semaphore lock for crtc flip > 8. remove static variables > > RFC v5: > 1. optimize encoder and connector code implementation > 2. use "platform_get_irq" and "platform_get_resource" > 3. drop useless function return type, drop unless debug log > 4. custom properties should be separate, so drop it > 5. use DRM_XXX replase pr_xxx > 6. drop dsi&dphy hal callback ops > 7. drop unless callback ops checking > 8. add comments for sprd dpu structure > > RFC v6: > 1. Access registers via readl/writel > 2. Checking for unsupported KMS properties (format, rotation, blend_mode, > etc) on plane_check ops > 3. Remove always true checks for dpu core ops > > RFC v7: > 1. Fix DTC unit name warnings > 2. Fix the problem of maintainers > 3. Call drmm_mode_config_init to mode config init > 4. Embed drm_device in sprd_drm and use devm_drm_dev_alloc > 5. Replace DRM_XXX with drm_xxx on KMS module, but not suitable for other > subsystems > 6. Remove plane_update stuff, dpu handles all the HW update in > crtc->atomic_flush > 7. Dsi&Dphy Code structure adjustment, all move to "sprd/" > > v0: > 1. Remove dpu_core_ops stuff layer for sprd drtc driver, but dpu_layer > need to keeping. > Because all the HW update in crtc->atomic_flush, we need temporary > storage all layers for > the dpu pageflip of atomic_flush. > 2. Add ports subnode with port@X. > > v1: > 1. Remove dphy and dsi graph binding, merge the dphy driver into the dsi. > 2. Add commit messages for Unisoc's virtual nodes. > > v2: > 1. Use drm_xxx to replace all DRM_XXX. > 2. Use kzalloc to replace devm_kzalloc for sprd_dsi/sprd_dpu structure > init. > 3. Remove dpu_core_ops midlayer. > > v3: > 1. Remove dpu_layer midlayer and commit layers by aotmic_update > > Kevin Tang (6): > dt-bindings: display: add Unisoc's drm master bindings > drm/sprd: add Unisoc's drm kms master > dt-bindings: display: add Unisoc's dpu bindings > drm/sprd: add Unisoc's drm display controller driver > dt-bindings: display: add Unisoc's mipi dsi controller bindings > drm/sprd: add Unisoc's drm mipi dsi&dphy driver > > .../display/sprd/sprd,display-subsystem.yaml | 64 + > .../bindings/display/sprd/sprd,sharkl3-dpu.yaml | 77 + > .../display/sprd/sprd,sharkl3-dsi-host.yaml | 102 ++ > drivers/gpu/drm/Kconfig | 2 + > drivers/gpu/drm/Makefile | 1 + > drivers/gpu/drm/sprd/Kconfig | 13 + > drivers/gpu/drm/sprd/Makefile | 8 + > drivers/gpu/drm/sprd/dw_dsi_ctrl.c | 794 +++++++++++ > drivers/gpu/drm/sprd/dw_dsi_ctrl.h | 1475 > ++++++++++++++++++++ > drivers/gpu/drm/sprd/dw_dsi_ctrl_ppi.c | 157 +++ > drivers/gpu/drm/sprd/dw_dsi_ctrl_ppi.h | 26 + > drivers/gpu/drm/sprd/megacores_pll.c | 317 +++++ > drivers/gpu/drm/sprd/megacores_pll.h | 146 ++ > drivers/gpu/drm/sprd/sprd_dpu.c | 985 +++++++++++++ > drivers/gpu/drm/sprd/sprd_dpu.h | 120 ++ > drivers/gpu/drm/sprd/sprd_drm.c | 224 +++ > drivers/gpu/drm/sprd/sprd_drm.h | 19 + > drivers/gpu/drm/sprd/sprd_dsi.c | 1162 +++++++++++++++ > drivers/gpu/drm/sprd/sprd_dsi.h | 107 ++ > 19 files changed, 5799 insertions(+) > create mode 100644 > Documentation/devicetree/bindings/display/sprd/sprd,display-subsystem.yaml > create mode 100644 > Documentation/devicetree/bindings/display/sprd/sprd,sharkl3-dpu.yaml > create mode 100644 > Documentation/devicetree/bindings/display/sprd/sprd,sharkl3-dsi-host.yaml > create mode 100644 drivers/gpu/drm/sprd/Kconfig > create mode 100644 drivers/gpu/drm/sprd/Makefile > create mode 100644 drivers/gpu/drm/sprd/dw_dsi_ctrl.c > create mode 100644 drivers/gpu/drm/sprd/dw_dsi_ctrl.h > create mode 100644 drivers/gpu/drm/sprd/dw_dsi_ctrl_ppi.c > create mode 100644 drivers/gpu/drm/sprd/dw_dsi_ctrl_ppi.h > create mode 100644 drivers/gpu/drm/sprd/megacores_pll.c > create mode 100644 drivers/gpu/drm/sprd/megacores_pll.h > create mode 100644 drivers/gpu/drm/sprd/sprd_dpu.c > create mode 100644 drivers/gpu/drm/sprd/sprd_dpu.h > create mode 100644 drivers/gpu/drm/sprd/sprd_drm.c > create mode 100644 drivers/gpu/drm/sprd/sprd_drm.h > create mode 100644 drivers/gpu/drm/sprd/sprd_dsi.c > create mode 100644 drivers/gpu/drm/sprd/sprd_dsi.h > > -- > 2.7.4 > >
