Hi Zou,
These set of patches are meant to work on OMAP3430 SDP with camkit v3, which contains MT9p012 sensor and DW9710 lens driver.
We currently have omap zoom ldp board implementation as W.I.P., so it's expected that you don't have your camera sensor detected yet. We'll be posting the patches in this list as soon as we have them ready.
This error you're getting for cam_mclk is something which we are working out with the power management team, but it shouldn't be a problem for getting that clock to work.
Regards,
Sergio

Hi:
I'm using omap zoom ldp board, and i enable omap34xx cam option in kernel.
My kernel version is v2.6.26-ti-07252008, which including most of the 15
patches, just having minor different.
During boot, it reported"Clock cam_mclk didn't enable in 100000 tries",
but init has been finished successfully.
After booting up , I tried to access /dev/video/0, but kernel reported
no such device.
Adding debug info, I found that video_device[0] is NULL.
and in
omap34xxcam_probe() ->
v4l2_int_device_register()->v4l2_int_device_try_attach_all()->m->u.master->attach(s)
but omap34xxcam_device_register() never been called. so cam failed to
register it.
Could you give me some advices? Does it work on your board?
