[PATCH v4 6/9] regulator: mt6359: Add support for MT6359 regulator

From: Hsin-Hsiung Wang
Date: Wed Dec 16 2020 - 02:49:33 EST

From: Wen Su <wen.su@xxxxxxxxxxxx>

The MT6359 is a regulator found on boards based on MediaTek MT6779 and
probably other SoCs. It is a so called pmic and connects as a slave to
SoC using SPI, wrapped inside the pmic-wrapper.
