i.MX6SX uses the v6 LCDIF controller, while i.MX28 uses the older v4
version. The driver has supported the "fsl,imx6sx-lcdif" compatible string
since the initial commit:
commit 45d59d704080 ("drm: Add new driver for MXSFB controller")
Therefore the fallback compatible string "fsl,imx28-lcdif" is not required
and can be removed.
It is required - you are changing the ABI and possibly impacting other
users without valid reason ("not required and can be removed" is not a
reason).
Best regards,
