-config VIDEO_PVRUSB2

-	---help---
-	  This is a video4linux driver for Conexant 23416 based
-	  usb2 personal video recorder devices.
-
-	  To compile this driver as a module, choose M here: the
-	  module will be called pvrusb2
-
-config VIDEO_PVRUSB2_SYSFS
-	bool "pvrusb2 sysfs support (EXPERIMENTAL)"
-	default y
-	depends on VIDEO_PVRUSB2 && SYSFS && EXPERIMENTAL
-	---help---
-	  This option enables the operation of a sysfs based
-	  interface for query and control of the pvrusb2 driver.
-
-	  This is not generally needed for v4l applications,
-	  although certain applications are optimized to take
-	  advantage of this feature.
-
-	  If you are in doubt, say Y.
-
-	  Note: This feature is experimental and subject to change.

-	select MEDIA_TUNER_TDA8290 if !MEDIA_TUNER_CUSTOMISE
-	---help---
-
-	  This option enables a DVB interface for the pvrusb2 driver.
-	  If your device does not support digital television, this
-	  feature will have no affect on the driver's operation.
-
-	  If you are in doubt, say Y.
-
-config VIDEO_PVRUSB2_DEBUGIFC
-	bool "pvrusb2 debug interface"
-	depends on VIDEO_PVRUSB2_SYSFS
-	---help---
-	  This option enables the inclusion of a debug interface
-	  in the pvrusb2 driver, hosted through sysfs.
-
-	  You do not need to select this option unless you plan
-	  on debugging the driver or performing a manual firmware
-	  extraction.
-
-	  If you are in doubt, say N.
