Kernel-4.18.0-80.el8_mcr20a

• MCR20A IEEE 802.15.4 *

Required properties:

• compatible: should be “nxp,mcr20a”
• spi-max-frequency: maximal bus speed, should be set to a frequency

      lower than 9000000 depends sync or async operation mode
  

• reg: the chipselect index
• interrupts: the interrupt generated by the device. Non high-level

      can occur deadlocks while handling isr.
  

Optional properties:

• rst_b-gpio: GPIO spec for the RST_B pin

Example:

mcr20a@0 {
    compatible = "nxp,mcr20a";
    spi-max-frequency = <9000000>;
    reg = <0>;
    interrupts = <17 2>;
    interrupt-parent = <&gpio>;
    rst_b-gpio = <&gpio 27 1>
};
