From f67ff1bd58f0c102f0194c3888ddbc4a87dd1382 Mon Sep 17 00:00:00 2001 From: Hsin-Hsiung Wang Date: Fri, 23 Aug 2019 11:45:28 +0800 Subject: [PATCH] regulator: mt6358: Add support for MT6358 regulator The MT6358 is a regulator found on boards based on MediaTek MT8183 and probably other SoCs. It is a so called pmic and connects as a slave to SoC using SPI, wrapped inside the pmic-wrapper.
