This currently introduces an extra file to the arch/arm/mach-omap2
directory: board-rm680-camera.c. Keeping the device tree in mind, the
context of the file could be represented as static data with one exception:
the external clock to the sensor.
This external clock is provide

The purpose of the link_validate() op is to allow an entity driver to ensure
that the properties of the pads at the both ends of the link are suitable
for starting the pipeline. link_validate is called on sink pads on active

One quick comment about your patch; I've noticed that you've declared two new

Hi Laurent,
It actually blocks at VIDIOC_DQBUF ioctl and not in STREAMON ioctl.
Looks like the data is not available.
Any way of verifying if OMAP is receiving data. Wonder why i keep

Is my media-ctl setting up things correctly?
Thank you.
