I'm testing using the driver, using a parallel interface: https://patchwork.kernel.org/patch/10129463/ The bus is 8-bits wide, and like I was saying, we had a separate driver for the ov5640 that is working fine with that driver, so the hardware setup works, and the capture driver should be mostly ok too. By dumping the registers, I've seen some differences on the clock setup, I'll try to hack something tomorrow and let you know :) Thanks!
