Hello Hugues, thank you for the patch series. I am having a go with your patches, and although they seem alright, I don't seem to be able to grab a non-black picture on the iWave iwg20d in plain DVP mode, but if I switch to BT656 just by setting register 0x4730 to 0x01 (I know, it's a nasty hack...) I can get something sensible out. At the moment there is no proper BT656 support in the driver, I was wondering if you have any plans to enhance the ov5640 driver a little bit further to add proper BT656 support as it may be convenient. Do you know if someone else was able to get DVP to work by means of this patch series on a non-STM32 platform?
