So, patch 1/24 needs to be amended with this diff --git a/drivers/gpu/drm/rockchip/rockchip_lvds.c b/drivers/gpu/drm/rockchip/rockchip_lvds.c index e67f4ea28c0e..3f33034b3f58 100644 --- a/drivers/gpu/drm/rockchip/rockchip_lvds.c +++ b/drivers/gpu/drm/rockchip/rockchip_lvds.c @@ -377,8 +377,10 @@ static int rockchip_lvds_bind(struct device *dev, struct device *master, } if (lvds->panel) remote = lvds->panel->dev->of_node; - else + else if (lvds->bridge->of_node) remote = lvds->bridge->of_node; + else + remote = lvds->bridge->owner->of_node; if (of_property_read_string(dev->of_node, "rockchip,output", &name)) /* default set it as output rgb */ lvds->output = DISPLAY_OUTPUT_RGB; and patch 22/24 with this diff --git a/drivers/gpu/drm/rockchip/rockchip_lvds.c b/drivers/gpu/drm/rockchip/rockchip_lvds.c index 3f33034b3f58..8c82fa647536 100644 --- a/drivers/gpu/drm/rockchip/rockchip_lvds.c +++ b/drivers/gpu/drm/rockchip/rockchip_lvds.c @@ -377,8 +377,6 @@ static int rockchip_lvds_bind(struct device *dev, struct device *master, } if (lvds->panel) remote = lvds->panel->dev->of_node; - else if (lvds->bridge->of_node) - remote = lvds->bridge->of_node; else remote = lvds->bridge->owner->of_node; if (of_property_read_string(dev->of_node, "rockchip,output", &name)) But that is of course just a stop-gap. The real fix is to adapt to the "drm: bridge: Add support for static image formats" series from Jacopo. But that's orthogonal.
