So we should not limit the monitors that can be connected by hardcoding the auo,b133htn01 1080p panel. - The default resolution on the LVDS interface needs to be WXGA or less. Otherwise when a 1080p monitor is connected to the HDMI port there is no output on both the LVDS and HDMI ports since a single IPU on i.MX6 can not handle two 1080p displays. With the panel entry removed from the devicetree, drm driver defaults the resolution on LVDS interface to XGA. Once in userspace, applications can set the desired resolution on LVDS interface over IPU2 CRTC.
