From 006cea3aeced7f3d67fe2849da7724683853d87d Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Tue, 1 Apr 2014 16:45:00 +0300 Subject: [PATCH] mfd: twl6040: Move register patching earlier in probe Make sure that we patch the ACCCTL register as the first thing when the driver loads, thus configuring I2C fast mode and i2c access for dual access registers.
