Date: Mon, 5 Dec 2011 11:44:39 +0000 From: Mark Brown <broonie@...nsource.wolfsonmicro.com> To: Liam Girdwood <lrg@...com>, Thomas Abraham <thomas.abraham@...aro.org> Cc: linux-kernel@...r.kernel.org, patches@...nsource.wolfsonmicro.com, Mark Brown <broonie@...nsource.wolfsonmicro.com> Subject: [PATCH] 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.
