no, wrong place. No dvb on it.

We have a HOWTO for simple gpio remotes on the v4l wiki.

For this one the TODO list can be found in the mail archives.

Mike pulled that one in and I had to defend the auto detection for a
prior card they did try to steel ;)

Separate Composite1 is missing, it is on vmux = 3.
Test composite over s-video, likely this is on vmux = 0.
S-Video is likely wrong, the other Yuan card has it on vmux = 7
The amux for radio is likely wrong. Try amux = TV too.
The gpiomask and the radio switch look suspicious.
Most other cards switch to radio on gpio21, 0x0200000.
The card could need eeprom detection, since it has the same subsystem
IDs than the UPMOST_PURPLE_TV.

With that one it shares also a device at 0xf4. (0x7a seven bit)
On the Upmost it is the i2c remote controller for which Wang-Chan Chen
added support in ir-kbd-i2c. You can try on that one.

Here is some eeprom dump from his card.
You can pick something for detection, maybe the c2 byte on yours.
