The following warning is seen when building with W=1: arch/arm/boot/dts/imx7s.dtsi:551.39-553.7: Warning (unique_unit_address): /soc/aips-bus@30000000/ocotp-ctrl@30350000/temp-grade@10: duplicate unit-address (also used in node /soc/aips-bus@30000000/ocotp-ctrl@30350000/speed-grade@10) Since temp-grade and speed-grade point to the same node, replace them by a single one to avoid the duplicate unit-address warning.
