MVEBU comphy drivers -------------------- COMPHY controllers can be found on the following Marvell MVEBU SoCs: * Armada 7k/8k (on the CP110) * Armada 3700 It provides a number of shared PHYs used by various interfaces (network, SATA, USB, PCIe...). Required properties: - compatible: should be one of: * "marvell,comphy-cp110" for Armada 7k/8k * "marvell,comphy-a3700" for Armada 3700 - reg: should contain the COMPHY register(s) location(s) and length(s). * 1 entry for Armada 7k/8k * 4 entries for Armada 3700 along with the corresponding reg-names properties, memory areas are: * Generic COMPHY registers * Lane 1 (PCIe/GbE) * Lane 0 (USB3/GbE) * Lane 2 (SATA/USB3) - marvell,system-controller: should contain a phandle to the system controller node (only for Armada 7k/8k) - #address-cells: should be 1. - #size-cells: should be 0. Optional properlties: - clocks: pointers to the reference clocks for this device (CP110 only), consequently: MG clock, MG Core clock, AXI clock. - clock-names: names of used clocks for CP110 only, must be : "mg_clk", "mg_core_clk" and "axi_clk". A sub-node is required for each comphy lane provided by the comphy. Required properties (child nodes): - reg: COMPHY lane number. - #phy-cells : from the generic PHY bindings, must be 1. Defines the input port to use for a given comphy lane. Examples: CP11X_LABEL(comphy): phy@120000 { compatible = "marvell,comphy-cp110"; reg = <0x120000 0x6000>; marvell,system-controller = <&CP11X_LABEL(syscon0)>; clocks = <&CP11X_LABEL(clk) 1 5>, <&CP11X_LABEL(clk) 1 6>, <&CP11X_LABEL(clk) 1 18>; clock-names = "mg_clk", "mg_core_clk", "axi_clk"; #address-cells = <1>; #size-cells = <0>; CP11X_LABEL(comphy0): phy@0 { reg = <0>; #phy-cells = <1>; }; CP11X_LABEL(comphy1): phy@1 { reg = <1>; #phy-cells = <1>; }; }; comphy: phy@18300 { compatible = "marvell,comphy-a3700"; reg = <0x18300 0x300>, <0x1F000 0x400>, <0x5C000 0x400>, <0xe0178 0x8>; reg-names = "comphy", "lane1_pcie_gbe", "lane0_usb3_gbe", "lane2_sata_usb3"; #address-cells = <1>; #size-cells = <0>; comphy0: phy@0 { reg = <0>; #phy-cells = <1>; }; comphy1: phy@1 { reg = <1>; #phy-cells = <1>; }; comphy2: phy@2 { reg = <2>; #phy-cells = <1>; }; };
