[PATCH 0/4] thermal: imx: Add nvmem-cells binding on imx6sx

From: Leonard Crestez

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 WaÃmann <LW@xxxxxxxxxxxxxxxxxxx> in reply
to a mail adding imx6ul/ull support:

A previous attempt just reinterpreted the fsl,tempmon-data phandle as nvmem.
Code was actually written to use nvmem-cells first but I thought that
reinterpreting existing devicetree properties would be interesting.
