The Digital Video Port (DVP, the 16-bit variant) of the RK3568 VICAP
is broken out to the PF5 mainboard expansion header.
Enable it in the device tree overlay for the WolfVision PF5 IO
Expander board.

Habidere,

This patch was skipped when the RK3568 series was applied, as the
MEDIA_PCLK_SAMPLE_DUAL_EDGE definition was introduced in the very same
series.

With the definition mainline for two kernel releases now, it should be
safe to merge this device tree modification.

Thanks in advance!

Applied, thanks!

After talking with Michael and both of us getting grey hair from
the whole mailmap thing, we agreed that I'll just adapt the author
myself.

I've applied the patch now as it's just a leaf-overlay of a single
leaf-board, so no real harm can happen here and I don't want to
have to remember all the address details in a day or two ;-) .

The git log will of course again show the @collabora.com, because
the mailmap translates the author-address again.

The From should match the first Signed-off-by line.

All later Signed-off-bys are from "other" people handling the patch,
i.e. that other Michael Riesch ;-)

Hmm... First of all, the Signed-off-by line is correct, this patch stems
from my WolfVision era. But then with the .mailmap entry I created when
the era ended, I cannot set the patch author (and thus the From line)
correctly.

Let me try again without this entry...

Yeah that guy's pretty weird!
