	string "SPI driver's name to use to access MCR20A"
	default SPI_0_NAME

	  This option is mandatory to set which SPI controller to use in order
	  to actually control the MCR20A chip.

config IEEE802154_MCR20A_SPI_FREQ
	int "SPI system frequency"
	default 4000000
	help
	  This option sets the SPI controller's frequency. Beware this value
	  depends on the SPI controller being used and also on the system
	  clock.

config IEEE802154_MCR20A_SPI_SLAVE
	int "SPI slave linked to MCR20A"
	default 0
	help
	  This option sets the SPI slave number SPI controller has to switch
	  to when dealing with MCR20A chip.

	bool "Manage SPI CS through a GPIO pin"

	This option is useful if one needs to manage SPI CS through a GPIO
	pin to by-pass the SPI controller's CS logic.

	This option is mandatory to set which GPIO controller to use in order
	to actually emulate the SPI CS.

	int "GPIO PIN to use to drive SPI CS through"
	default 0

	This option is mandatory to set which GPIO pin to use in order
	to actually emulate the SPI CS.

config IEEE802154_MCR20A_RX_STACK_SIZE
	int "Driver's internal RX thread stack size"
	default 800
	help
	  This option sets the driver's stack size for its internal RX thread.
	  The default value should be sufficient, but in case it proves to be
	  a too little one, this option makes it easy to play with the size.

config IEEE802154_MCR20A_INIT_PRIO
	int "MCR20A initialization priority"
	default 80
	help
	  Set the initialization priority number. Do not mess with it unless
	  you know what you are doing. Beware mcr20a requires gpio and spi to
	  be ready first (and sometime gpio should be the very first as spi
	  might need it too). And of course it has to start before the net stack.
