[PATCH v6 7/9] dt-bindings: iio: adc: mt6359: Allow reg for SPMI PMICs AuxADC
Posted by AngeloGioacchino Del Regno 10 hours ago
When one or multiple Auxiliary ADC IPs are embedded in a SPMI PMIC
it is reachable at a specific address.

Allow specifying the `reg` property and make it a required one for
MediaTek MT6363/6373 PMICs as those communicate over SPMI and also
disallow it for the others (as it wouldn't be applicable).
