Function Documentation

int fimc_md_set_camclk ( struct v4l2_subdev sd,
bool  on 

fimc_md_set_camclk - peripheral sensor clock setup : sensor subdev to configure sclk_cam clock for : 1 to enable or 0 to disable the clock

There are 2 separate clock outputs available in the SoC for external image processors. These clocks are shared between all registered FIMC devices to which sensors can be attached, either directly or through the MIPI CSI receiver. The clock is allowed here to be used by multiple sensors concurrently if they use same frequency. This function should only be called when the graph mutex is held.
