+Broadcom AMAC Ethernet Controller Device Tree Bindings
+-------------------------------------------------------------
+
+Required properties:
+ - compatible: "brcm,amac" or "brcm,nsp-amac"
+ - reg:                Address and length of the GMAC registers,
+               Address and length of the GMAC IDM registers
+ - reg-names:  Names of the registers.  Must have both "amac_base" and
+               "idm_base"
+ - interrupts: Interrupt number
+
+Optional properties:
+- mac-address: See ethernet.txt file in the same directory

+Examples:
+
+amac0: ethernet@18022000 {
+       compatible = "brcm,nsp-amac";
+       reg = <0x18022000 0x1000>,
