Cover letter [RFC PATCH 0/3] bttv: convert to generic TEA575x interface
Hello,
this patch series removes the tea575x code from bttv and uses the common tea575x driver instead. Only set_frequency is implemented (signal/stereo detection or seek would require more changes to bttv).
It works fine on Video Highway Xtreme but I don't have the Miro/Pinnacle or Terratec Active Radio Upgrade to test.
Miro/Pinnacle seems to be simple and should work.
However, I don't understand the Terratec Active Radio Upgrade code. The HW seems to need IOR, IOW and CSEL signals that were taken from ISA bus on older cards (IOR and IOW directly and CSEL from some address decoder) and are emulated here using GPIOs. But the code manipulating these signals in bttv seems to be broken - it never asserts the IOR signal. If anyone has this HW, please test if I got that right.
