Some time ago, Michael Krufky started a mercurial tree for this device
and related ones. I began this patch from his changes, but all that
remains from them are the (largely non-applicable) tuner-attaching code
and identifier names. I have been very careful to make sure the chip
driver changes in this patch are no-ops on already supported devices,
which I can't test; I recommend those who can test them to enable those
changes as appropriate.
I had hoped to include IR support in this patch, but the IR core does
not currently build against the .31 kernel with which I am testing, so
that will need to be a second patch when more feasible. To review, every
100ms, bit 4 is set in register 0xe0 in the AU8524 demod, register 0xe1
is read, and if bit 4 is on in it, 0x28 bytes are read from 0xe3.
