+* 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>
