Kernel-4.18.0-80.el8_mrf24j40

• MRF24J40 IEEE 802.15.4 *

Required properties:

• compatible: should be “microchip,mrf24j40”, “microchip,mrf24j40ma”,

      or "microchip,mrf24j40mc" depends on your transceiver
      board
  

• spi-max-frequency: maximal bus speed, should be set something under or equal

      10000000
  

• reg: the chipselect index
• interrupts: the interrupt generated by the device.

Example:

mrf24j40ma@0 {
    compatible = "microchip,mrf24j40ma";
    spi-max-frequency = <8500000>;
    reg = <0>;
    interrupts = <19 8>;
    interrupt-parent = <&gpio3>;
};
