It is found on the PMI8998 and PM660 Qualcomm PMICs. The RRADC has to calibrate some ADC values based on which chip fab the PMIC was produced in, to facilitate this the patch ("mfd: qcom-spmi-pmic: expose the PMIC revid information to clients") exposes the PMIC revision information as a struct and registers it as driver data in the Qualcomm SPMI PMIC driver so that it can be read by the RRADC. Changes since v1: * Rework the RRADC driver based on Jonathan's feedback * Pick up Rob's reviewed by for the dt-binding patch.
