description: >
  This device controls the PHY for both the USB 1.1 OHCI and USB 2.0 OTG
  controllers on DA8xx SoCs.

  It also requires a "syscon" node with compatible = "ti,da830-cfgchip", "syscon"
  to access the CFGCHIP2 register.

properties:
  compatible:
    items:
      - const: ti,da830-usb-phy

  '#phy-cells':
    const: 1
    description:
      Consumers of this device should use index 0 for the USB 2.0 phy device and
      index 1 for the USB 1.1 phy device.

  clocks:
    maxItems: 2

  clock-names:
    items:
      - const: usb0_clk48
