* Broadcom 6802 driver bindings

The Broadcom 6802 driver provides access to the moca core and EPORT settings
on the 6802.  This driver controls the 6802 over a SPI link.  The device-tree
node must be a child of a SPI controller node.

Required properties:

 compatible        : should contain "brcm,bcm6802"
 reg               : SPI chip select
 hw-rev            : HW revision number (must be 0x2002 for 6802)
 enet-id           : phandle to the internal (local) ethernet port 
 rf-band           : rf band string, possible values "highrf, midrf, wanrf,
			ext_d, d_low, d_high, e, f, g"
 local-mac-address : MAC address assigned to the 6802
 interrupt-parent  : phandle of interrupt controller
 interrupts        : interrupt used by bcm6802 driver
 ethernet-ports    : node containing configuration information for the 6802's
			two RGMII ports

Optional properties:

 spi-max-frequency : SPI clock rate
 spi-cpol          : SPI clock polarity
 spi-cpha          : SPI clock phase
 chip-id           : override chip ID


The ethernet-ports node can contain the following sub-nodes:

 rgmii0            : Configuration of the 6802's RGMII0 port
 rgmii1            : Configuration of the 6802's RGMII0 port

These two rgmii nodes can contain the following properties:

 phy-mode: See Documentation/devicetree/bindings/net/ethernet.txt
 fixed-link: See Documentation/devicetree/bindings/net/fixed-link.txt
 
Example:

	 ext_moca@0 {
			compatible = "brcm,bcm6802";
			reg = <0x0>;
			spi-max-frequency = <12000000>;
			spi-cpol;
			spi-cpha;
			hw-rev = <0x2002>;
			enet-id = <0x75>;
			rf-band = "ext_d";
			local-mac-address = [ 00 10 18 03 25 d7 ];
			interrupt-parent = <0x76>;
			interrupts = <0x11 0x4>;
			ethernet-ports {
				rgmii0 {
					phy-mode = "rgmii-rxid";
					fixed-link {
						speed = <1000>;
						full-duplex;
					}
				}

				rgmii1 {
				}
			}
	 };
