[PATCH 01/46] regulator: ab8500: Further populate initialisation registers

From: Lee Jones
Date: Thu Mar 21 2013 - 12:00:11 EST


This patch supplies access to some extra settings provided by the
AB8500 regulator device. We also update some of the existing
initialisation values in accordance with internal ST-Ericsson code
submissions. This single patch was originally a collection of updates
which have been squashed together to aid with clarity.
