From c2219e4dac89fbd2ac4c75a95062a02d558211c1 Mon Sep 17 00:00:00 2001 From: Robert Jarzmik Date: Sun, 22 Apr 2012 23:24:00 +0200 Subject: [PATCH] ARM: pxa: mioa701 add camera output enable gpio The Micron MT9M111 camera chip needs its output enable to be activated in order to work. The bootloader is not required to activate it, so do it in machine code.
