[PATCH 00/13] add AUXADC, EFUSE and thermal drivers for the MediaTek mt6323 PMIC

[Roman Vivchar via B4 Relay]

This series adds support for AUXADC, EFUSE and thermal drivers for the
MediaTek mt6323 PMIC

Usually vendor downstream kernels for devices with mt6323 include various
useful drivers like AUXADC, thermal, fuel gauge etc. Bring it to the
upstream kernel by rewriting some drivers from 3.18 vendor tree.

Currently dt-bindings limit some values like ADC channel count and names
to what mt6323 has, but the drivers were designed in a way to support
other PMICs like mt6358 (which has very similar thermal logic).

Tested on the MediaTek mt6572 and mt8163 SoCs, both paired with mt6323.
