From 4294ad1c52caad3239404cea9e0cbfeb435e3a25 Mon Sep 17 00:00:00 2001 From: Manuel Lauss Date: Wed, 29 Jan 2014 19:11:46 +0100 Subject: [PATCH] MIPS: Alchemy: Fix DB1100 GPIO registration With CONFIG_GPIOLIB=y gpios need to be requested before they can be modified. Request the SD carddetect pins, and drop the SPI direction setup, as the driver does that for us anyway. This gets rid of a lot of WARN_ON()s triggered by GPIO core, and restores functionality of the touschreen controller.
