[RFC,4/6] SoC Camera: add support for g_parm / s_parm operations
Commit Message
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-2.6.35-rc3 on Amstrad Delta.
