From 2066930de6296ef7470de11eaa9b8bc9129721e8 Mon Sep 17 00:00:00 2001 From: Baruch Siach Date: Sun, 4 Jul 2010 07:55:10 +0300 Subject: mx2_camera: Add soc_camera support for i.MX25/i.MX27 This is the soc_camera support developed by Sascha Hauer for the i.MX27. Alan Carvalho de Assis modified the original driver to get it working on more recent kernels. I modified it further to add support for i.MX25. This driver has been tested on i.MX25 and i.MX27 based platforms.
