config CONFIG_RADIO_SI470X
        tristate "Silicon Labs Si470x FM Radio Receiver support"
        depends on CONFIG_VIDEO_V4L2
	help
	  This is a driver for devices with the Silicon Labs SI470x
	  chip (either via CONFIG_USB or CONFIG_I2C buses).

	  Say Y here if you want to connect this type of radio to your
	  computer's CONFIG_USB port or if it is used by some other driver
	  via CONFIG_I2C bus.

	  To compile this driver as a module, choose CONFIG_M here: the
	  module will be called radio-si470x-common.

config CONFIG_USB_SI470X
	tristate "Silicon Labs Si470x FM Radio Receiver support with USB"
	depends on CONFIG_USB && CONFIG_RADIO_SI470X
	help
	  This is a driver for CONFIG_USB devices with the Silicon Labs SI470x
	  chip. Currently these devices are known to work:
	  - 10c4:818a: Silicon Labs CONFIG_USB FM Radio Reference Design
	  - 06e1:a155: ADS/Tech FM Radio Receiver (formerly Instant FM Music)
	  - 1b80:d700: KWorld CONFIG_USB FM Radio SnapMusic Mobile 700 (FM700)
	  - 10c5:819a: Sanei Electric FM CONFIG_USB Radio (aka DealExtreme.com PCear)

	  Sound is provided by the ALSA CONFIG_USB Audio/MIDI driver. Therefore
	  if you don't want to use the device solely for CONFIG_RDS receiving,
	  it is recommended to also select CONFIG_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/media/v4l-drivers/si470x.rst

	  Say Y here if you want to connect this type of radio to your
	  computer's CONFIG_USB port.

	  To compile this driver as a module, choose CONFIG_M here: the
	  module will be called radio-usb-si470x.

config CONFIG_I2C_SI470X
	tristate "Silicon Labs Si470x FM Radio Receiver support with I2C"
	depends on CONFIG_I2C && CONFIG_RADIO_SI470X
	help
	  This is a driver for CONFIG_I2C devices with the Silicon Labs SI470x
	  chip.

	  Say Y here if you want to connect this type of radio to your
	  computer's CONFIG_I2C port.

	  To compile this driver as a module, choose CONFIG_M here: the
	  module will be called radio-i2c-si470x.
