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".
Signed-off-by: Janusz Krzysztofik jkrzyszt@tis.icnet.pl --- v1->v2 changes: - no functional changes, - refreshed against linux-2.6.36-rc3
