Please explain the differences done during conversion in the commit msg.
There was no imx51 compatible in the binding before.

This allows only imx51 and disallows imx27 alone, which is not what old
bindings were saying.

The best if you just test it on DTS. Please run `make dtbs_check W=1`
(see Documentation/devicetree/bindings/writing-schema.rst or
https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/
for instructions).

You should see two warnings for imx31 and imx51. You need imx31 as well
(and changes against pure conversion should be mentioned in commit msg).


Best regards,
