[PATCH v2 0/5] thermal: imx: Add nvmem-cells binding on imx6sx

[Leonard Crestez <leonard.crestez-3arQi8VN3Tc@public.gmane.org>]

On imx6sx accessing OCOTP directly is wrong because the ocotp clock needs to be
enabled first. Fix this by adding a nvmem-cells binding and using it on imx6sx,
imx6ul and imx6ull.

The existing binding is kept around because it works fine on imx6qdl.

This was initially reported by Lothar Waßmann <LW-bxm8fMRDkQLDiMYJYoSAnRvVK+yQ3ZXh@public.gmane.org> in reply
to a patch adding imx6ul/ull support:
