PATCH 2 is to apply the drm_bridge_connector helper. PATCH 3-5 are to move the panel/bridge parsing to the Analogix side. PATCH 6 is to attach the next bridge on Analogix side uniformly. PATCH 7-8 are to apply the panel_bridge helper.

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. Changes in v6: - Move legacy bridge driver out of imx directory for multi-platform use. - Apply DRM legacy bridge to parse display timings intead of implementing the same codes only for Exynos DP. - Ensure last bridge determines EDID/modes detection capabilities in DRM bridge_connector driver. - Remove unnecessary drm_bridge_get_modes() in analogix_dp_bridge_get_modes(). - Simplify analogix_dp_bridge_edid_read(). - If the next is a bridge, set DRM_BRIDGE_OP_DETECT and return connector_status_connected in analogix_dp_bridge_detect(). - Set flag DRM_BRIDGE_ATTACH_NO_CONNECTOR for bridge attachment while binding. Meanwhile, make DRM_BRIDGE_ATTACH_NO_CONNECTOR unsuppported in analogix_dp_bridge_attach(). - Move the next bridge attachment to the Analogix side rather than scattered on Rockchip and Exynos sides. - Remove the unnecessary analogix_dp_bridge_get_modes(). - Squash [PATCH v5 15/17] into [PATCH v5 17/17]. - Fix the &drm_bridge->ops to DRM_BRIDGE_OP_EDID | DRM_BRIDGE_OP_DETECT. Changes in v7: - As Luca suggested, simplify the code and related comment for bridge_connector modifications. Additionally, move the commit related to bridge_connector to the top of this patch series. - Rename legacy-bridge driver to of-display-mode-bridge driver. - Remove unnecessary API drm_bridge_is_legacy() and apply a temporary flag &exynos_dp_device.has_of_bridge instead, which will be removed finally. - Remove exynos_dp_legacy_bridge_init() and inline API devm_drm_of_display_mode_bridge(). Changes in v8: - Adapt the related modifications to the newest bridge_connector driver. Changes in v9: - Fix the Kconfig help text for CONFIG_DRM_OF_DISPLAY_MODE_BRIDGE. - Add Tested-by tag from Heiko. Changes in v10: - Fix to use dev_err_probe() in newly added API analogix_dp_finish_probe(). - Expaned commit message for [PATCH v9 9/15] and [PATCH v9 10/15]. - Split [PATCH v9 9/15] into serval smaller commits. - Add Reviewed-by tags from Luca. Changes in v11: - Merge [PATCH v10 12/18] into [PATCH v10 11/18]. - Fix the bridge flag to 'flags | DRM_BRIDGE_ATTACH_NO_CONNECTOR' in [PATCH v10 11/18]. - Add Reviewed-by tags from Luca. Changes in v12: - Restore accidentally removed DRM_BRIDGE_CONNECTOR Kconfig in v10. Changes in v13: - Modify '(on rk3588)' to '# rk3588' for Tested-by tag as discussed in https://lore.kernel.org/all/571cc85a-3310-4b56-a3ef-3aab698192f6@rock-chips.com/ - Rebase [PATCH v12 2/17] after commit 02df94d98ff8 ("drm/imx: parallel-display: add DRM_DISPLAY_HELPER for DRM_IMX_PARALLEL_DISPLAY") - Rebase [PATCH v12 7/17] and [PATCH v12 11/17] after commit 01962a191242 ("drm/rockchip: analogix: Convert to drm_output_color_format") Changes in v14: - Picked from https://lore.kernel.org/all/20260409065301.446670-1-damon.ding@rock-chips.com/ - Add Reviewed-by tags. - Apply __free() to call drm_bridge_put() in CRC ralted functions of Analogix side. -- 2.34.1
