From 11e38e11afcdd598d0978746924a001e3e7cb723 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Tue, 1 Apr 2014 16:44:59 +0300 Subject: mfd: twl6040: Select i2c fast mode as default with regmap patch All boards using twl6040 configures the i2c bus to 400KHz. While twl6040's defaults to normal mode (100KHz). So far twl6040 has no problem with i2c communication in this configuration it is safer to select fast i2c mode.
