"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. v5: 1. Remove subdir-ccflgas-y for Makefile. 2. Keep the selects sorted by alphabet for Kconfig. 3. Fix the checkpatch warnings. 4. Use mode_set_nofb instead of mode_valid callback. 5. Follow the OF-Graph bindings, use of_graph_get_port_by_id instead of of_parse_phandle. 6. Use zpos to represent the layer position. 7. Rebase to last drm misc branch. 8. Remove panel_in port for dsi node. 9. Drop the dsi ip file prefix. 10. Add Signed-off-by for dsi&dphy patch. 11. Use the mode_flags of mipi_dsi_device to setup crtc DPI and EDPI mode. v6: 1. Disable and clear interrupts before register dpu IRQ 2. Init dpi config used by crtc_state->adjusted_mode on mode_set_nofb 3. Remove enable_irq and disable_irq function call. 4. Remove drm_format_info function call. 5. Redesign the way to access the dsi register. 6. Reduce the dsi_context member variables. v7: 1. Fix codeing style issue by checkpatch. 2. Drop the pll registers structure define. 3. Use bridge API instead of drm panel API. 4. Register mipi_dsi_host on probe phase; 5. Remove iommu error interrupt handling function. 6. Remove some unused function.
