From 613330a0f73b2698b2210ea89092eb56635fc5d8 Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Sat, 3 Mar 2012 12:40:02 +0100 Subject: regulator: provide a helper for registering a fixed regulator Some devices require a regulator to work, but boards may not have a software controllable regulator for this device. Provide a helper function to make it simpler for these boards to register a fixed regulator as a dummy regulator.
