IMX6Q: using parallel CSI on second IPU

Selea — Wed, 25 Jun 2014 15:56:32 GMT

I'm trying to use a parallel sensor on the second parallel CSI input. this second paralle (according with documentation) can be routed only on the second IPU.

so in my DTS i have IPU_id=1 and CSI_id=1.

the driver probe is working fine, the sensor is found , configured and the signal seems to be present and correct. the V4L2 device is created (/dev/video2) but when i try to read from it it sat read timeout...

Any suggestion.

I add my DTS files (they are customized for our board startting from phytec one). As you will see I addedd a Cmos sensor AR0134 that shoul use the parallel input port on the second IPU.

and i configured the second paralle port pins as well.

The driver is loaded, the sensor is configured on I2C, and i see the device created, but when i try to read from that one it not works : just say timeout... seems that the port is not capturing

so i think i missing some initialization on CSI or IPU.
