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