1*4882a593SmuzhiyunMarvell SOC USB controllers
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunThis controller is integrated in Armada 3700/8K.
4*4882a593SmuzhiyunIt uses the same properties as a generic XHCI host controller
5*4882a593Smuzhiyun
6*4882a593SmuzhiyunRequired properties :
7*4882a593Smuzhiyun - compatible: should be one or more of:
8*4882a593Smuzhiyun   - "marvell,armada3700-xhci", "generic-xhci" for Armada 37xx SoCs
9*4882a593Smuzhiyun   - "marvell,armada-8k-xhci", "generic-xhci" for Armada A8K SoCs
10*4882a593Smuzhiyun - reg: should contain address and length of the standard XHCI
11*4882a593Smuzhiyun   register set for the device.
12*4882a593Smuzhiyun - interrupts: one XHCI interrupt should be described here.
13*4882a593Smuzhiyun
14*4882a593SmuzhiyunOptional properties:
15*4882a593Smuzhiyun - clocks: phandle to system controller clock driving this unit
16*4882a593Smuzhiyun - vbus-supply : If present, specifies the fixed regulator to be turned on
17*4882a593Smuzhiyun   for providing power to the USB VBUS rail.
18*4882a593Smuzhiyun
19*4882a593SmuzhiyunExample:
20*4882a593Smuzhiyun	cpm_usb3_0: usb3@500000 {
21*4882a593Smuzhiyun		compatible = "marvell,armada-8k-xhci",
22*4882a593Smuzhiyun			     "generic-xhci";
23*4882a593Smuzhiyun		reg = <0x500000 0x4000>;
24*4882a593Smuzhiyun		interrupts = <GIC_SPI 62 IRQ_TYPE_LEVEL_HIGH>;
25*4882a593Smuzhiyun		clocks = <&cpm_syscon0 1 22>;
26*4882a593Smuzhiyun		vbus-supply = <&reg_usb3h0_vbus>;
27*4882a593Smuzhiyun		status = "disabled";
28*4882a593Smuzhiyun	};
