From 7e6213f4345c3798b7fb7af41d221e2fd77ec6a6 Mon Sep 17 00:00:00 2001 From: Paul Kocialkowski Date: Fri, 5 Feb 2016 19:42:19 +0100 Subject: regulator: lp872x: Add enable GPIO pin support LP872x regulators are made active via the EN pin, which might be hooked to a GPIO. This adds support for driving the GPIO high when the driver is in use.
