[PATCHv3,2/2] dib0700: add support for Xbox One Digital TV Tuner
Commit Message
From: Olli Salonen <olli.salonen@iki.fi>
Xbox One Digital TV Tuner is a low-cost USB 2.0 multistandard TV tuner. It
supports DVB-T, DVB-T2 and DVB-C broadcast standards.
USB bridge: DibCom 0700C
Demodulator: Panasonic MN88472
Tuner: TDA18250BHN
The demodulator requires firmware. Download one from here:

Thanks for this contribution! It's good to finally have an example of
card support within the dib0700 driver that can serve an an example of
using the newer method of frontend attachment.
It would be nice to move some of the attachment code out of the
card-specific `_attach()` function into a common function, but since
this is the only attachment that works this way, leaving things as-is
is fine enough for now. After we convert some of the other
`_attach()` functions, or adding some new ones using this method, we
may want to refactor this a bit.
Meanwhile, this is good for merge. Nice work.
