From 80ec831e8069c3da06bd96db196422d736d364bc Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Fri, 15 Nov 2013 16:36:03 -0800 Subject: [PATCH] mfd: twl-core: Fix passing of platform data in the device tree case Since we still need to rely on a mix of device tree initialized drivers and legacy platform data initialize drivers, let's fix the passing of platform data to twl4030-gpio. As the twl4030 GPIO is initialized by twl-core.c, we need to register the auxdata for twl4030 GPIO in twl-core.c.
