| Enable IEEE802154_MCR20A driver with RAW channel |
| |
| The MCR20A driver with RAW channel allows to export radio interface |
| over USB making an USB 802.15.4 dongle. |

| 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. |

| 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. |

| 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. |
