net: emaclite: Support multiple phys connected to one MDIO bus

Linux Kernel / Linux Kernel - Michal Simek [xilinx.com] - 30 May 2013 19:08 UTC

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>; } ;
