From: Andrey Smirnov Date: Tue, 10 Jan 2017 16:30:14 +0000 (-0800) Subject: regulator: anatop: Add support for "anatop-enable-bit" X-Git-Tag: v4.11-rc1~154^2~6^2 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ca7734ad77b4ffb83a03c80b8d64d40c7ef49263;p=karo-tx-linux.git regulator: anatop: Add support for "anatop-enable-bit" Add code to support support for "anatop-enable-bit" device-tree property. This property translates to LINREG_ENABLE bit in real hardware and is present on 1p1, 2p5 and 3p0 regulators on i.MX6 and 1p0d regulator on i.MX7.
