Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

Support for the Leadtek WinView 601 TV/FM by Jon Tombs <jon@gte.esi.us.es>
|
|
|
|
This card is basically the same as all the rest (Bt484A, Philips tuner),
|
|
the main difference is that they have attached a programmable attenuator to 3
|
|
GPIO lines in order to give some volume control. They have also stuck an
|
|
infra-red remote control decoded on the board, I will add support for this
|
|
when I get time (it simple generates an interrupt for each key press, with
|
|
the key code is placed in the GPIO port).
|
|
|
|
I don't yet have any application to test the radio support. The tuner
|
|
frequency setting should work but it is possible that the audio multiplexer
|
|
is wrong. If it doesn't work, send me email.
|
|
|
|
|
|
- No Thanks to Leadtek they refused to answer any questions about their
|
|
hardware. The driver was written by visual inspection of the card. If you
|
|
use this driver, send an email insult to them, and tell them you won't
|
|
continue buying their hardware unless they support Linux.
|
|
|
|
- Little thanks to Princeton Technology Corp (http://www.princeton.com.tw)
|
|
who make the audio attenuator. Their publicly available data-sheet available
|
|
on their web site doesn't include the chip programming information! Hidden
|
|
on their server are the full data-sheets, but don't ask how I found it.
|
|
|
|
To use the driver I use the following options, the tuner and pll settings might
|
|
be different in your country

insmod videodev

insmod i2c scan=1 i2c_debug=0 verbose=0
