1*137b1883SKonstantin PorotchkinMarvell SOC USB controllers
2*137b1883SKonstantin Porotchkin
3*137b1883SKonstantin PorotchkinThis controller is integrated in Armada 3700/8K.
4*137b1883SKonstantin PorotchkinIt uses the same properties as a generic XHCI host controller
5*137b1883SKonstantin Porotchkin
6*137b1883SKonstantin PorotchkinRequired properties :
7*137b1883SKonstantin Porotchkin - compatible: should be one or more of:
8*137b1883SKonstantin Porotchkin   - "marvell,armada3700-xhci", "generic-xhci" for Armada 37xx SoCs
9*137b1883SKonstantin Porotchkin   - "marvell,armada-8k-xhci", "generic-xhci" for Armada A8K SoCs
10*137b1883SKonstantin Porotchkin - reg: should contain address and length of the standard XHCI
11*137b1883SKonstantin Porotchkin   register set for the device.
12*137b1883SKonstantin Porotchkin - interrupts: one XHCI interrupt should be described here.
13*137b1883SKonstantin Porotchkin
14*137b1883SKonstantin PorotchkinOptional properties:
15*137b1883SKonstantin Porotchkin - clocks: phandle to system controller clock driving this unit
16*137b1883SKonstantin Porotchkin - vbus-supply : If present, specifies the fixed regulator to be turned on
17*137b1883SKonstantin Porotchkin   for providing power to the USB VBUS rail.
