Liu Ying 20da948e3a drm/bridge: adv7511: Attach next bridge without creating connector ... The connector is created by either this ADV7511 bridge driver or any DRM device driver/previous bridge driver, so this ADV7511 bridge driver should not let the next bridge driver create connector. If the next bridge is a HDMI connector, the next bridge driver would fail to attach bridge from display_connector_attach() without the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag. Add that flag to drm_bridge_attach() function call in adv7511_bridge_attach() to fix the issue. This fixes the issue where the HDMI connector bridge fails to attach to the previous ADV7535 bridge on i.MX8MP EVK platform: [ 2.216442] [drm:drm_bridge_attach] *ERROR* failed to attach bridge /hdmi-connector to encoder None-37: -22 [ 2.220675] mmc1: SDHCI controller on 30b50000.mmc [30b50000.mmc] using ADMA [ 2.226262] [drm:drm_bridge_attach] *ERROR* failed to attach bridge /soc@0/bus@30800000/i2c@30a30000/hdmi@3d to encoder None-37: -22 [ 2.245204] [drm:drm_bridge_attach] *ERROR* failed to attach bridge /soc@0/bus@32c00000/dsi@32e60000 to encoder None-37: -22 [ 2.256445] imx-lcdif 32e80000.display-controller: error -EINVAL: Failed to attach bridge for endpoint0 [ 2.265850] imx-lcdif 32e80000.display-controller: error -EINVAL: Cannot connect bridge [ 2.274009] imx-lcdif 32e80000.display-controller: probe with driver imx-lcdif failed with error -22 Fixes: 14b3cdbd0e ("drm/bridge: adv7511: make it honour next bridge in DT") Signed-off-by: Liu Ying <victor.liu@nxp.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Reviewed-by: Robert Foss <rfoss@kernel.org> Acked-by: Sui Jingfeng <suijingfeng@bosc.ac.cn> Reviewed-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240513080243.3952292-1-victor.liu@nxp.com Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>		2024-05-20 00:23:23 +03:00
