[PATCH v1 0/4] MediaTek MT6357/8/9 PMIC Auxiliary ADC support

[AngeloGioacchino Del Regno]

This series adds support for the Auxiliary ADC IP found on the MediaTek
MT635(x) PMICs, including MT6357, 6358 and 6359, exposing various ADC
channels for accessory detection (usually, on 3.5mm jack), battery
voltage, PMIC temperature, PMIC-integrated voltage regulators, and
others, depending on the PMIC model.
