The patch looks good, but the DT binding documentation patch should
normally precede the related driver patch in the series. That way we
could avoid checkpatch warnings like:
WARNING: DT compatible string "fsl,imx21-emmaprp" appears un-documented -- check ./Documentation/devicetree/bindings/
#76: FILE: drivers/media/platform/mx2_emmaprp.c:1010:
+ { .compatible = "fsl,imx21-emmaprp", },
Wouldn't it make sense to also ad second entry with "fsl,imx27-emmaprp"
compatible ?
Could you also fix the remaining checkpatch warnings:
