From: Fabio Estevam <festevam@denx.de>
mx6sl.dtsi and imx6sll.dtsi have the following lcdif entries:
compatible = "fsl,imx6sl-lcdif", "fsl,imx28-lcdif";
This causes dt-schema warnings as the current binding only
allow 'fsl,imx6sx-lcdif' as fallback.
['fsl,imx6sl-lcdif', 'fsl,imx28-lcdif'] is too long
['fsl,imx6sll-lcdif', 'fsl,imx28-lcdif'] is too long
The imx6sx-lcdif programming model has more advanced features, such
as overlay plane and the CRC32 support than the imx28-lcdif IP.
Expand the imx6sl/imx6sll lcdif fallbacks to accept a less specific
fsl,imx28-lcdif fallback:
compatible = "fsl,imx6sl-lcdif", "fsl,imx6sx-lcdif", "fsl,imx28-lcdif";
This helps keeping DT compatibility as well as using the more advanced
lcdif features found on imx6sl and imx6sll.

The LCDIF IP on i.MX6SL and i.MX6SLL is compatible with i.MX6SX.
Provide a more specific "fsl,imx6sx-lcdif" compatible and still keep
"fsl,imx28-lcdif" for DT compatibility.
