-The cx88 driver
-===============
-
-Author: Gerd Hoffmann
-
-This is a v4l2 device driver for the cx2388x chip.
-
-
-Current status
---------------
-
-video
- - Works.
- - Overlay isn't supported.
-
-audio
- - Works. The TV standard detection is made by the driver, as the
- hardware has bugs to auto-detect.
- - audio data dma (i.e. recording without loopback cable to the
- sound card) is supported via cx88-alsa.
-
-vbi
- - Works.

-How to add support for new cards
---------------------------------
-
-The driver needs some config info for the TV cards. This stuff is in
-cx88-cards.c. If the driver doesn't work well you likely need a new
-entry for your card in that file. Check the kernel log (using dmesg)
-to see whenever the driver knows your card or not. There is a line
-like this one:
-
-.. code-block:: none
-
- cx8800[0]: subsystem: 0070:3400, board: Hauppauge WinTV \
- 34xxx models [card=1,autodetected]
-
-If your card is listed as "board: UNKNOWN/GENERIC" it is unknown to
-the driver. What to do then?
-
-1) Try upgrading to the latest snapshot, maybe it has been added
- meanwhile.
-2) You can try to create a new entry yourself, have a look at
- cx88-cards.c. If that worked, mail me your changes as unified
- diff ("diff -u").
-3) Or you can mail me the config information. We need at least the
- following information to add the card:
-
- - the PCI Subsystem ID ("0070:3400" from the line above,
- "lspci -v" output is fine too).
- - the tuner type used by the card. You can try to find one by
- trial-and-error using the tuner=<n> insmod option. If you
- know which one the card has you can also have a look at the
- list in CARDLIST.tuner
