From a950cb741bb62d5f23860755388ad4e93dd2a185 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 5 Feb 2013 20:10:57 +0100 Subject: [PATCH] pinctrl/abx500: adjust offset for get_mode() The set_mode() and get_mode() functions in the abx500 were not mirrored, leading to the wrong GPIO control bits being read out.
