mygica hdcap

[James Klaas]

I just got one of these the other day and I was wondering if anyone
has looked at it.  It will take HDMI, component and composite input
plus stereo.  I have a picture I can post somewhere of the board.  It
has 3 main chips.

AD9985A - Component/composite input?
SIL9013CLU - Audio input?
TM6202 - HDMI input

I'm not sure if this falls under v4l since it has no tuner or dvb
since it captures digital video.

It looks like an at least semi-similar device to the Hauppauge HD-PVR,
which is under v4l, so it probably does make sense here. Not aware of
anyone working on your specific hardware, but Hans Verkuil posted some
patches for some at least similar-ish Analog Devices chips not too
long ago, which might be relevant to at least that part of your card...

Just like with the Hauppauge Colossus, the Analog Devices part is
relatively easy to bring up.  In both cases the hard part is that
there is no bridge driver for either chip, and writing a PCIe driver
from scratch without the datasheet is one of the more
difficult/annoying things for a device driver developer to have to do.

I've looked into the tm6200.  It would be a royal PITA.

Any progress made with this?  I have this same card and I can't find a
datasheet for tm6200.

Nobody has written an open source driver for the tm6200 (and nobody is
in the process of doing such), and there are no publicly available
datasheets for the part.
