From d2e7491e24e47aa0305455031fc1b9ea1f97b555 Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Fri, 15 Nov 2013 13:48:23 +0000 Subject: regulator: arizona-micsupp: Correct wm5110 voltage selection wm5110 provides different voltage configurations than the other Arizona parts, this patch adds support for this into the regulator driver. Also fixup the default for the configuration register for wm5110.
