No, it isn't. Kernel 3.6 works properly in our Visstrim M10 board and
the CSI clock frequency is the same as yours:

soc-camera-pdrv soc-camera-pdrv.0: Probing soc-camera-pdrv.0
mx2-camera mx2-camera.0: Camera driver attached to camera 0
ov7670 0-0021: chip found @ 0x42 (imx-i2c)
mx2-camera mx2-camera.0: Invalid format code #1: 4098
mx2-camera mx2-camera.0: Invalid format code #1: 4098
mx2-camera mx2-camera.0: Camera driver detached from camera 0
mx2-camera mx2-camera.0: MX2 Camera (CSI) driver probed, clock
frequency: 66500000
