Ugh.

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

                /* 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

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.

Cheers,
Peter
