[PATCH] mmp-camera: specify XO-1.75 clock speed

2012-05-15 Thread Daniel Drake
For the ov7670 camera to return images at the requested frame rate, it needs to make calculations based on the clock speed, which is a completely external factor (depends on the wiring of the system). On the XO-1.75, which is the only known mmp-camera user, the camera is clocked at 48MHz. Pass th
