From 2ced445e2ddf65f484a489161accddf475676965 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 20 Feb 2012 21:42:17 +0100 Subject: mfd: Parametrize ab8500 IRQ masks and registers This makes the AB8500 state struct contain the IRQ mask and register offsets previously hard-coded so as to make room for more AB8500 variants.
