[PATCH 0/3] ARM: imx: Make DRM_MXSFB and FB_MXS coexist

From: Leonard Crestez

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")

Leonard Crestez (3):
drm: mxsfb: Change driver.name to mxsfb-drm
fbdev: mxsfb: Return ENODEV on missing display node
ARM: imx_v6_v7_defconfig: Enable DRM_MXSFB
