-config DVB_CINERGYT2
-	tristate "Terratec CinergyT2/qanu USB2 DVB-T receiver"
-	depends on DVB_CORE && USB && INPUT
-	help
-	  Support for "TerraTec CinergyT2" USB2.0 Highspeed DVB Receivers
-
-	  Say Y if you own such a device and want to use it.
-
-
-config DVB_CINERGYT2_TUNING
-	bool "sophisticated fine-tuning for CinergyT2 cards"
-	depends on DVB_CINERGYT2
-	help
-	  Here you can fine-tune some parameters of the CinergyT2 driver.
-
-	  Normally you don't need to touch this, but in exotic setups you
-	  may fine-tune your setup and adjust e.g. DMA buffer sizes for
-	  a particular application.
-
-
-config DVB_CINERGYT2_STREAM_URB_COUNT
-	int "Number of queued USB Request Blocks for Highspeed Stream Transfers"
-	depends on DVB_CINERGYT2_TUNING
-	default "32"
-	help
-	  USB Request Blocks for Highspeed Stream transfers are scheduled in
-	  a queue for the Host Controller.
-
-	  Usually the default value is a safe choice.
-
-	  You may increase this number if you are using this device in a
-	  Server Environment with many high-traffic USB Highspeed devices
-	  sharing the same USB bus.
-
-
-config DVB_CINERGYT2_STREAM_BUF_SIZE
-	int "Size of URB Stream Buffers for Highspeed Transfers"
-	depends on DVB_CINERGYT2_TUNING
-	default "512"
-	help
-	  Should be a multiple of native buffer size of 512 bytes.
-	  Default value is a safe choice.
-
-	  You may increase this number if you are using this device in a
-	  Server Environment with many high-traffic USB Highspeed devices
-	  sharing the same USB bus.
-
-
-config DVB_CINERGYT2_QUERY_INTERVAL
-	int "Status update interval [milliseconds]"
-	depends on DVB_CINERGYT2_TUNING
-	default "250"
-	help
-	  This is the interval for status readouts from the demodulator.
-	  You may try lower values if you need more responsive signal quality
-	  measurements.
-
-	  Please keep in mind that these updates cause traffic on the tuner
-	  control bus and thus may or may not affect reception sensitivity.
-
-	  The default value should be a safe choice for common applications.
-
-
-config DVB_CINERGYT2_ENABLE_RC_INPUT_DEVICE
-	bool "Register the onboard IR Remote Control Receiver as Input Device"
-	depends on DVB_CINERGYT2_TUNING
-	default y
-	help
-	  Enable this option if you want to use the onboard Infrared Remote
-	  Control Receiver as Linux-Input device.
-
-	  Right now only the keycode table for the default Remote Control
-	  delivered with the device is supported, please see the driver
-	  source code to find out how to add support for other controls.
-
-
-config DVB_CINERGYT2_RC_QUERY_INTERVAL
-	int "Infrared Remote Controller update interval [milliseconds]"
-	depends on DVB_CINERGYT2_TUNING && DVB_CINERGYT2_ENABLE_RC_INPUT_DEVICE
-	default "50"
-	help
-	  If you have a very fast-repeating remote control you can try lower
-	  values, for normal consumer receivers the default value should be
-	  a safe choice.
