[PATCH 3/4] regulator: mt6359: Add support for MT6359 regulator

From: Wen Su
Date: Wed Oct 16 2019 - 05:42:20 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.
