It's is a fix, according to the dt binding of video interface. So it should be applied before: "media: atmel-isi: parse the DT parameters for vsync/hsync/pixclock polarity". it has no impact in older kernel as the driver doesn't parse that property yet. > > So, should I wait for the enhancements to enter media git tree or can I > take them anyway? yes, you can take it without waiting for the media tree.

On at91sam9x5ek/at91sam9m10g45ek/sama5d3xek boards, we use the parallel connection for ov2640. So we must set the hsync/vsync property (1 means active high). Otherwise, the connection would be seen as BT.656 or BT.1120.
