PHY nodes
If the device tree is used to describe networking interfaces, U-Boot expects a
node for each PHY. Parent node for such a PHY node is expected to correspond to
a MDIO bus and the bus is used to access the PHY.
Required properties:
- reg : The ID number for the phy, usually a small integer
Example:
ethernet-phy@0 {
compatible = "ethernet-phy-id0141.0e90", "ethernet-phy-ieee802.3-c22";
interrupt-parent = <&PIC>;
interrupts = <35 IRQ_TYPE_EDGE_RISING>;
reg = <0>;
resets = <&rst 8>;
reset-names = "phy";
reset-gpios = <&gpio1 4 GPIO_ACTIVE_LOW>;
reset-assert-us = <1000>;
reset-deassert-us = <2000>;
};
