From e3365d0974ed64157f5b5a576c611057dc40a595 Mon Sep 17 00:00:00 2001 From: Chris Ruehl Date: Wed, 22 Jan 2014 11:14:52 +0800 Subject: [PATCH] pinctrl: imx27: fix offset calculation in imx_read_2bit The offset for the 2bit register calculate wrong, this patch fixes the problem. The debugfs printout for oconf, iconfa, iconfb now shows the real values.
