| 2 | |
| 3 | This controller is integrated in Armada 3700/8K. |
| 4 | It uses the same properties as a generic XHCI host controller |
| 5 | |
| 6 | Required properties : |
| 7 | - compatible: should be one or more of: |
| 8 | - "marvell,armada3700-xhci", "generic-xhci" for Armada 37xx SoCs |
| 9 | - "marvell,armada-8k-xhci", "generic-xhci" for Armada A8K SoCs |
| 10 | - reg: should contain address and length of the standard XHCI |
| 11 | register set for the device. |
| 12 | - interrupts: one XHCI interrupt should be described here. |
| 13 | |
| 14 | Optional properties: |
| 15 | - clocks: phandle to system controller clock driving this unit |
| 16 | - vbus-supply : If present, specifies the fixed regulator to be turned on |
| 17 | for providing power to the USB VBUS rail. |
| 18 | |
| 19 | Example: |
| 20 | cpm_usb3_0: usb3@500000 { |
| 21 | compatible = "marvell,armada-8k-xhci", |
| 22 | "generic-xhci"; |
| 23 | reg = <0x500000 0x4000>; |
| 24 | interrupts = <GIC_SPI 62 IRQ_TYPE_LEVEL_HIGH>; |
| 25 | clocks = <&cpm_syscon0 1 22>; |
| 26 | vbus-supply = <®_usb3h0_vbus>; |
| 27 | status = "disabled"; |
| 28 | }; |
