1PHY nodes 2 3If the device tree is used to describe networking interfaces, U-Boot expects a 4node for each PHY. Parent node for such a PHY node is expected to correspond to 5a MDIO bus and the bus is used to access the PHY. 6 7Required properties: 8 9 - reg : The ID number for the phy, usually a small integer 10 11Example: 12 13ethernet-phy@0 { 14 compatible = "ethernet-phy-id0141.0e90", "ethernet-phy-ieee802.3-c22"; 15 interrupt-parent = <&PIC>; 16 interrupts = <35 IRQ_TYPE_EDGE_RISING>; 17 reg = <0>; 18 19 resets = <&rst 8>; 20 reset-names = "phy"; 21 reset-gpios = <&gpio1 4 GPIO_ACTIVE_LOW>; 22 reset-assert-us = <1000>; 23 reset-deassert-us = <2000>; 24}; 25
