Mon, 13 Apr 2026 15:25:46 +0200

drm/bridge: analogix_dp: Add new API analogix_dp_finish_probe()Since the panel/bridge should logically be positioned behind theAnalogix bridge in the display pipeline, it makes sense to handlethe panel/bridge parsing on the Analogix side. Therefore, we adda new API analogix_dp_finish_probe(), which combines the panel/bridgeparsing with component addition, to do it.In order to process component binding right after the probe completes,the &analogix_dp_plat_data.ops is newly added to pass &component_ops,for which the &dp_aux_ep_device_with_data.done_probing() of DP AUX busonly supports passing &drm_dp_aux.Signed-off-by: Damon Ding Reviewed-by: Dmitry Baryshkov Tested-by: Marek Szyprowski Tested-by: Heiko Stuebner # rk3588Link: https://patch.msgid.link/20260413132551.1049307-4-damon.ding@rock-chips.com[Luca: propagate 'depends on OF' to DRM_ANALOGIX_DP and reverse dependencies]Signed-off-by: Luca Ceresoli List of files: /linux/drivers/gpu/drm/exynos/Kconfig
