+        depends on USB && RADIO_SI470X
+        ---help---
+          This is a driver for USB devices with the Silicon Labs SI470x
+          chip. Currently these devices are known to work:
+          - 10c4:818a: Silicon Labs USB FM Radio Reference Design
+          - 06e1:a155: ADS/Tech FM Radio Receiver (formerly Instant FM Music)
+          - 1b80:d700: KWorld USB FM Radio SnapMusic Mobile 700 (FM700)
+          - 10c5:819a: Sanei Electric FM USB Radio (aka DealExtreme.com PCear)
+
+          Sound is provided by the ALSA USB Audio/MIDI driver. Therefore
+          if you don't want to use the device solely for RDS receiving,
+          it is recommended to also select SND_USB_AUDIO.
+
+          Please have a look at the documentation, especially on how
+          to redirect the audio stream from the radio to your sound device:
+          Documentation/video4linux/si470x.txt
+
+          Say Y here if you want to connect this type of radio to your
+          computer's USB port.
+
+          To compile this driver as a module, choose M here: the
+          module will be called radio-usb-si470x.
