Broadcom AMAC Ethernet Controller Device Tree Bindings

-------------------------------------------------------------



Required properties:

 - compatible:	"brcm,amac"

		"brcm,nsp-amac"

		"brcm,ns2-amac"

 - reg:		Address and length of the register set for the device. It

		contains the information of registers in the same order as

		described by reg-names

 - reg-names:	Names of the registers.

		"amac_base":	Address and length of the GMAC registers

		"idm_base":	Address and length of the GMAC IDM registers

				(required for NSP and Northstar2)

		"nicpm_base":	Address and length of the NIC Port Manager

				registers (required for Northstar2)

 - interrupts:	Interrupt number



The MAC address will be determined using the optional properties

defined in ethernet.txt.



Examples:



amac0: ethernet@18022000 {

	compatible = "brcm,nsp-amac";

	reg = <0x18022000 0x1000>,

	      <0x18110000 0x1000>;

	reg-names = "amac_base", "idm_base";

	interrupts = <GIC_SPI 147 IRQ_TYPE_LEVEL_HIGH>;

};
