It's simple, we have a full working platform with ov5640 that support all the resolutions, that can be test by anyone and we have an industrial product that has some problem on high xvclk because it can not give us a clear image but this is limited on another design and another camera module vendor. Problem is not in the kernel code but it's just on relic design. We are getting the information on that module and see if inside is really using the xvclk or it's clocked by some other things. We have only the schematic up to the connector.
