2022-06-20drm: Drop drm_blend.h from drm_crtc.hVille Syrjälä
drm_crtc.h has no need for drm_blend.h, so don't include it. Avoids useless rebuilds of the entire universe when touching drm_blend.h. Quite a few placs do currently depend on drm_blend.h without actually including it directly. All of those need to be fixed up.

2021-12-10drm/sprd: add Unisoc's drm mipi dsi&dphy driverKevin Tang
Adds dsi host controller support for the Unisoc's display subsystem. Adds dsi phy support for the Unisoc's display subsystem. Only MIPI DSI Displays supported, DP/TV/HMDI will be support in the feature. v1: - Remove dphy and dsi graph binding, merge the dphy driver into the dsi. v2: - Use drm_xxx to replace all DRM_XXX. - Use kzalloc to replace devm_kzalloc for sprd_dsi structure init. v4: - Use drmm_helpers to allocate encoder. - Move allocate encoder and connector to bind function. v5: - Drop the dsi ip file prefix. - Fix the checkpatch warnings. - Add Signed-off-by for dsi&dphy patch. - Use the mode_flags of mipi_dsi_device to setup crtc DPI and EDPI mode. v6: - Redesign the way to access the dsi register. - Reduce the dsi_context member variables. v7: - Fix codeing style issue by checkpatch. - Drop the pll registers structure define. - Use bridge API instead of drm panel API. - Register mipi_dsi_host on probe phase; - Remove some unused function. v8: - Fix missing signed-off-by. - Move component_add to dsi_host.attach callback.

2021-12-10drm/sprd: add Unisoc's drm display controller driverKevin Tang
Adds DPU(Display Processor Unit) support for the Unisoc's display subsystem. It's support multi planes, scaler, rotation, PQ(Picture Quality) and more. v2: - Use drm_xxx to replace all DRM_XXX. - Use kzalloc to replace devm_kzalloc for sprd_dpu structure init. v3: - Remove dpu_layer stuff layer and commit layers by aotmic_update v4: - Use drmm_helpers to allocate crtc and planes. - Move rotation enum definitions to crtc layer reg bitfields. - Move allocate crtc and planes to bind function. v5: - Fix the checkpatch warnings. - Use mode_set_nofb instead of mode_valid callback. - Follow the OF-Graph bindings, use of_graph_get_port_by_id instead of of_parse_phandle. - Use zpos to represent the layer position. - Rebase to last drm misc branch. v6: - Disable and clear interrupts before register dpu IRQ - Init dpi config used by crtc_state->adjusted_mode on mode_set_nofb - Remove enable_irq and disable_irq function call. - Remove drm_format_info function call. v7: - Remove iommu error interrupt handling function.
