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@xxxxxxxxxxxxxxxxxxx> in reply to a mail adding imx6ul/ull support: Link: https://lkml.org/lkml/2017/6/9/578 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.
