This patch works for the parallel-display driver but not for imx-ldb
(I didn't test the TV or HDMI drivers). It works when the DRM driver is
built as modules, but when it is non-modular I get a framebuffer
device which is useable from userspace, but no output on the LVDS
interface.
When reverting 503fe87bd0a8346ba9d8b7f49115dcd0a4185226 instead of
applying the above patch, the builtin driver works normally.
