[media] radio-rtrack2: Convert to radio-isa
Tested with v4l2-compliance, but not with actual hardware. Contact the linux-media mailinglist if you have this card! Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Choose Y here if you have this FM radio card, and then fill in the
|
||||
port address below.
|
||||
|
||||
In order to control your radio card, you will need to use programs
|
||||
that are compatible with the Video For Linux API. Information on
|
||||
this API and pointers to "v4l" programs may be found at
|
||||
<file:Documentation/video4linux/API.html>.
|
||||
Note: this driver hasn't been tested since a long time due to lack
|
||||
of hardware. If you have this hardware, then please contact the
|
||||
linux-media mailinglist.
|
||||
|
||||
To compile this driver as a module, choose M here: the
|
||||
module will be called radio-rtrack2.
