I've made good progress on finding the sequence needed to initialize the
MT352. I'm not done quite yet, so I probably won't have something for
test until next weekend.
I think the MPC718 variants might use at least 3 different DVB-T
demodulators: Mitel/Zarlink MT352, Zarlink ZL10353, or some DiBcom chip
supported by one of the dib7000x drivers. It looks like you might have
an older card.

Given that your board uses a MT352, which is rather old, I'd expect the
board doesn't use the XC3028L - low power tuner. Please do confirm
though.

This should be easy to do, but not done yet.

I'm almost sure it's GPIO pin 0. Please confirm. If not 0, it will
likely be a low number like 1, 2, 3, ...
