1 Freescale SOC USB controllers
3 The device node for a USB controller that is part of a Freescale
9  - compatible : Should be "fsl-usb2-mph" for multi port host USB
10    controllers, or "fsl-usb2-dr" for dual role USB controllers
11    or "fsl,mpc5121-usb2-dr" for dual role USB controllers of MPC5121.
12    Wherever applicable, the IP version of the USB controller should
13    also be mentioned (for eg. fsl-usb2-dr-v2.2 for bsc9132).
14  - phy_type : For multi port host USB controllers, should be one of
15    "ulpi", or "serial". For dual role USB controllers, should be
17  - reg : Offset and length of the register set for the device
18  - port0 : boolean; if defined, indicates port0 is connected for
19    fsl-usb2-mph compatible controllers.  Either this property or
20    "port1" (or both) must be defined for "fsl-usb2-mph" compatible
22  - port1 : boolean; if defined, indicates port1 is connected for
23    fsl-usb2-mph compatible controllers.  Either this property or
24    "port0" (or both) must be defined for "fsl-usb2-mph" compatible
26  - dr_mode : indicates the working mode for "fsl-usb2-dr" compatible
31  - interrupts : <a b> where a is the interrupt number and b is a
35    controller you have.
38  - fsl,invert-drvvbus : boolean; for MPC5121 USB0 only. Indicates the
40  - fsl,invert-pwr-fault : boolean; for MPC5121 USB0 only. Indicates
43 Example multi port host USB controller device node :
44 	usb@22000 {
45 		compatible = "fsl-usb2-mph";
47 		#address-cells = <1>;
48 		#size-cells = <0>;
49 		interrupt-parent = <700>;
56 Example dual role USB controller device node :
57 	usb@23000 {
58 		compatible = "fsl-usb2-dr";
60 		#address-cells = <1>;
61 		#size-cells = <0>;
62 		interrupt-parent = <700>;
68 Example dual role USB controller device node for MPC5121ADS:
70 	usb@4000 {
71 		compatible = "fsl,mpc5121-usb2-dr";
73 		#address-cells = <1>;
74 		#size-cells = <0>;
75 		interrupt-parent = < &ipic >;
79 		fsl,invert-drvvbus;
80 		fsl,invert-pwr-fault;
