[E3-hacking] [PATCH v2 2/6] OMAP1: Add support for SoC camera interface

[Janusz Krzysztofik]

This patch adds support for SoC camera interface to OMAP1 devices.

Created and tested against linux-2.6.36-rc3 on Amstrad Delta.

For successfull compilation, requires a header file provided by PATCH 1/6 from 
this series, "SoC Camera: add driver for OMAP1 camera interface".
