From ab62aa931ed3512bc67857a03636756b96c78eae Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Mon, 5 Dec 2011 10:58:41 +0000 Subject: regulator: If a single voltage is set with device tree then set apply_uV Otherwise there is no way in the bindings to configure a fixed voltage via software. It seems reasonable to assume that if the binding explicitly specifies a voltage we want to actually use that voltage.
