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 v4: 1. Move the devm_drm_dev_alloc to master_ops->bind function. 2. The managed drmm_mode_config_init() it is no longer necessary for drivers to explicitly call drm_mode_config_cleanup, so delete it. 3. Use drmm_helpers to allocate crtc ,planes and encoder. 4. Move allocate crtc ,planes, encoder to bind funtion. 5. Move rotation enum definitions to crtc layer reg bitfields.
