+ tristate "BT8XX GPIO abuser"
+ depends on PCI && VIDEO_BT848=n
+ help
+ The BT8xx frame grabber chip has 24 GPIO pins than can be abused
+ as a cheap PCI GPIO card.
+ This chip can be found on Miro, Hauppauge and STB TV-cards.
+ The card needs to be physically altered for using it as a
+ GPIO card. For more information on how to build a GPIO card
+ from a BT8xx TV card, see the documentation file at
+ Documentation/bt8xxgpio.txt
+ If unsure, say N.
