[PATCH v2 0/4] nvmem: add support for the MediaTek mt6323 PMIC

[Roman Vivchar via B4 Relay]

This series adds support for the EFUSE found on the MediaTek mt6323 PMIC.

The previous version of the series for all AUXADC, EFUSE and thermal
drivers was split after Krzysztof's comment [1].
    
Tested on the MediaTek mt6572 and mt8163 SoCs (Ben), both paired with a
mt6323.
