menuconfig IEEE802154_MCR20A
bool "NXP MCR20A Driver support"
depends on NETWORKING && SPI
default n
if IEEE802154_MCR20A
config IEEE802154_MCR20A_DRV_NAME
string "NXP MCR20A Driver's name"
default "mcr20a"
help
This option sets the driver name
config IEEE802154_MCR20A_SPI_DRV_NAME
string "SPI driver's name to use to access MCR20A"
default SPI_0_NAME
help
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.
config MCR20A_GPIO_IRQ_B_NAME
string "GPIO device used for IRQ_B output of MCR20A"
default GPIO_MCUX_PORTB_NAME
config MCR20A_GPIO_IRQ_B_PIN
int "GPIO pin connected to IRQ_B output of MCR20A"
default 9
config MCR20A_GPIO_RESET_NAME
string "GPIO device used for RESET input of MCR20A"
default GPIO_MCUX_PORTA_NAME
config MCR20A_GPIO_RESET_PIN
int "GPIO pin connected to RESET input of MCR20A"
default 2
config MCR20A_IS_PART_OF_KW2XD_SIP
bool "MCR20A device is part of KW2xD SiP"
default n
help
If this option is set, the driver does not perform a hardware
reset and the CLK_OUT frequency is not set, instead these settings
are performed during the initialization of the SoC.

help
Configuration of the MCR20A clock output pin.
config MCR20A_CLK_OUT_DISABLED
bool "Disabled"

bool "32768 Hz"

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.
