Date: Wed, 5 Sep 2012 04:39:23 +0000 From: "Kim, Milo" <Milo.Kim@...com> To: Mark Brown <broonie@...nsource.wolfsonmicro.com> CC: "Girdwood, Liam" <lrg@...com>, "linux-kernel@...r.kernel.org" <linux-kernel@...r.kernel.org> Subject: [PATCH 3/5] regulator: lp872x: initialize the DVS mode The platform specific configuration(general_config) is optional. However, the DVS settings should be configured explicitly while loading the driver. This patch enables configuring the default DVS mode even though the platform data is not defined.
