Some imx boards have new drm-style bindings for lcdif devices but using them requires rebuilding the kernel with FB_MXS=n DRM_MXSFB=y.
It is relatively easy to allow both drivers to coexist by renaming drm/mxsfb to "mxsfb-drm" and making the old fbdev driver return -ENODEV instead of -ENOENT when it fails to find the display node.
This makes display on imx6sx-sdb "just work" with both styles of bindings. In order to test the old bindings I locally reverted commit 7caa59e0d40c ("ARM: dts: imx6sx-sdb: Convert from fbdev to drm bindings")
