1 Freescale SOC USB controllers
3 The device node for a USB controller that is part of a Freescale
4 SOC is as described in the document "Open Firmware Recommended
5 Practice : Universal Serial Bus" with the following modifications
9 - compatible : Should be "fsl-usb2-mph" for multi port host USB
10 controllers, or "fsl-usb2-dr" for dual role USB controllers
11 - phy_type : For multi port host USB controllers, should be one of
12 "ulpi", or "serial". For dual role USB controllers, should be
13 one of "ulpi", "utmi", "utmi_wide", or "serial".
14 - reg : Offset and length of the register set for the device
15 - port0 : boolean; if defined, indicates port0 is connected for
16 fsl-usb2-mph compatible controllers. Either this property or
17 "port1" (or both) must be defined for "fsl-usb2-mph" compatible
19 - port1 : boolean; if defined, indicates port1 is connected for
20 fsl-usb2-mph compatible controllers. Either this property or
21 "port0" (or both) must be defined for "fsl-usb2-mph" compatible
23 - dr_mode : indicates the working mode for "fsl-usb2-dr" compatible
24 controllers. Can be "host", "peripheral", or "otg". Default to
25 "host" if not defined for backward compatibility.
27 Recommended properties :
28 - interrupts : <a b> where a is the interrupt number and b is a
29 field that represents an encoding of the sense and level
30 information for the interrupt. This should be encoded based on
31 the information in section 2) depending on the type of interrupt
33 - interrupt-parent : the phandle for the interrupt controller that
34 services interrupts for this device.
36 Example multi port host USB controller device node :
38 compatible = "fsl-usb2-mph";
42 interrupt-parent = <700>;
49 Example dual role USB controller device node :
51 compatible = "fsl-usb2-dr";
55 interrupt-parent = <700>;
