Changes in v3: - Rebase for the existing devm_drm_bridge_alloc() applying commit. - Fix the typographical error of panel/bridge check in exynos_dp_bind(). - Squash all commits related to skip_connector deletion in both Exynos and Analogix code into one. - Apply panel_bridge helper to make the codes more concise. - Fix the handing of bridge in analogix_dp_bridge_get_modes(). - Remove unnecessary parameter struct drm_connector* for callback &analogix_dp_plat_data.attach(). - In order to decouple the connector driver and the bridge driver, move the bridge connector initilization to the Rockchip and Exynos sides. Changes in v4: - Rebase for the applied &drm_bridge_funcs.detect() modification commit. - Rename analogix_dp_find_panel_or_bridge() to analogix_dp_finish_probe(). - Drop the drmm_encoder_init() modification commit. - Rename the &analogix_dp_plat_data.bridge to &analogix_dp_plat_data.next_bridge. Changes in v5: - Add legacy bridge to parse the display-timings node under the dp node for Exynos side. - Move color format check to &drm_connector_helper_funcs.atomic_check() in order to get rid of &analogix_dp_plat_data.get_modes(). - Remove unused callback &analogix_dp_plat_data.get_modes(). - Distinguish the &drm_bridge->ops of Analogix bridge based on whether the downstream device is a panel, a bridge or neither. - Select DRM_DISPLAY_DP_AUX_BUS for DRM_ANALOGIX_DP, and remove it for ROCKCHIP_ANALOGIX_DP. - Apply rockchip_dp_attach() to support the next bridge attachment for the Rockchip side. - Move next_bridge attachment from Analogix side to Rockchip/Exynos sides. -- 2.34.1
