From ceee9dc13bf991b151701e3b720487b5e1589ba4 Mon Sep 17 00:00:00 2001 From: Yoshihiro Shimoda Date: Tue, 12 Jan 2021 18:01:00 +0900 Subject: [PATCH] regulator: bd9571mwv: Add BD9574MWF support Add support for BD9574MWF which is similar chip with BD9571MWV. Note that we don't support voltage rails VD{09,18,25,33} by this driver on BD9574. The VD09 voltage could be read from PMIC but that is not supported by this commit.
