Hi Laurent,
I'm working on a sensor driver with a parallel interface to the ISP. In my OMAP35x TRM (spruf98h.pdf), I only find 2 occurrences of "CCP2", with no discussion or description, whereas in the ISP sources on omap3camera/devel I see that it is a building block of the ISP. From the sources, I'm guessing that it is involved in interfacing a serial sensor data stream to the CCDC, and would be uninvolved in parallel data from a sensor.
Is the CCP2 indeed documented somewhere for the OMAP35x? Or is this perhaps only available in the OMAP34x?
In omap34xxcam_video_init(), the media_entity links are activated. In this if/else there,
if (vdev->vdev_sensor->entity.links[0].sink->entity ==
&isp->isp_csi2a.subdev.entity) {...} else {...}
the assumption is made that a sensor is either connected
A. (sensor->)CSI2A->CCDC or
B. sensor->CCP2->CCDC
but if I'm correct that the CCP2 is related to serial data, there is an option (C) missing for parallel data: sensor->CCDC. In fact, this is the link that is created in omap34xxcam_probe() if 'case ISP_INTERFACE_PARALLEL'. Is this correct, that I would need to add an 'else if' to get parallel data working?
sincerely,
Michael
