net: emaclite: Support multiple phys connected to one MDIO bus
For system which contains at least two ethernet IP where
one IP manage MDIO bus with several PHYs.
Example dts node:
ethernet_mac0: ethernet@81000000 {
compatible = "xlnx,xps-ethernetlite-1.00.a";
device_type = "network";
interrupt-parent = <&xps_intc_0>;
interrupts = < 1 0 >;
local-mac-address = [ 00 0a 35 00 db bb ];
phy-handle = <ðernet_mac0_phy0>;
reg = < 0x81000000 0x10000 >;
xlnx,duplex = <0x1>;
xlnx,family = "spartan3e";
xlnx,include-internal-loopback = <0x0>;
xlnx,include-mdio = <0x1>;
xlnx,rx-ping-pong = <0x0>;
xlnx,tx-ping-pong = <0x0>;
ethernet_mac0_mdio {
#address-cells = <1>;
#size-cells = <0>;
ethernet_mac0_phy0: phy@1 {
reg = <0x1>;
} ;
ethernet_mac0_phy1: phy@3 {
reg = <0x3>;
} ;
} ;
} ;
ethernet_mac2: ethernet@81040000 {
compatible = "xlnx,xps-ethernetlite-1.00.a";
device_type = "network";
interrupt-parent = <&xps_intc_0>;
interrupts = < 11 0 >;
local-mac-address = [ 00 0a 35 00 db bb ];
phy-handle = <ðernet_mac0_phy1>;
reg = < 0x81040000 0x10000 >;
xlnx,duplex = <0x1>;
xlnx,family = "spartan3e";
xlnx,include-internal-loopback = <0x0>;
xlnx,include-mdio = <0x0>;
xlnx,rx-ping-pong = <0x0>;
xlnx,tx-ping-pong = <0x0>;
} ;
