[PATCH 3/9] ARM: ux500: Remove AB8500 regulator register initialisation information

Lee Jones lee.jones at linaro.org
Thu Jul 5 09:06:06 EDT 2012


There is no need to initialise the AB8500's regulator registers, as
most of this work is already carried out by framework features, so
we can safely remove all traces from platform code.
