+        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.
