   4 Subject: [PATCH 6/8] OMAP3+: Voltage: add ABB data to voltage domains
   5
   6 Starting with OMAP36xx, some voltage domains have an ABB ldo meant to
   7 insure stability when that voltage domain is operating at a high OPP.
   8
   9 This patch adds struct omap_abb_instance to struct voltagedomain and
  10 populates the data for those voltage domains that have an ABB ldo on
  11 both 36xx and 44xx silicon.
