omap zoom lpd board clk init problem when booting "Clock cam_ick didn't enable in 100000 tries"

Hi:
When board reboot, driver tried to reset camera, there is error:
kernel version is v2.6.26-ti-07252008. Does anyone see it before?

I have tried to open /dev/video/0, but there is no such device.
and I add some debug info in isp_get call, and found that content of
register cm_fclken_cam is 03, and content of cm_icklen_cam is 0,but
cm_idlest_cam is 0x1, so clk init failed. For the kernel option I have 
choiced:

even there is some clk error report, but isp_get return successfully.
1. why there  is no such device?
2. do you know the sensor name of sensor module? and datasheet?
3. what's the interface used by ldp board to connect sensor? serial or 
parallel port?

Any suggestion will be appreciated.
