This patch adds support for g_parm / s_parm operations to the SoC Camera framework. It is usefull for checking/setting camera frame rate.
Example usage can be found in the previous patch from this series, "SoC Camera: add driver for OV6650 sensor".
Created and tested against linux-2.6.36-rc3 on Amstrad Delta.
Signed-off-by: Janusz Krzysztofik jkrzyszt@tis.icnet.pl --- v1->v2 changes: - no functional changes, - refreshed against linux-2.6.36-rc3.
