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.

Hi Josh,
Does this patch apply because of the new enhancement that you had
proposed in "media: atmel-isi: parse the DT parameters for
vsync/hsync/pixclock polarity" or does it apply even before?
Is it a fix that applies to older kernels?
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. Thanks.
Best Regards,
Josh Wu
Bye,
