f) Freescale SOC USB controllers
|
||||
|
||||
The device node for a USB controller that is part of a Freescale
|
||||
SOC is as described in the document "Open Firmware Recommended
|
||||
Practice : Universal Serial Bus" with the following modifications
|
||||
and additions :
|
||||
|
||||
Required properties :
|
||||
- compatible : Should be "fsl-usb2-mph" for multi port host usb
|
||||
controllers, or "fsl-usb2-dr" for dual role usb controllers
|
||||
- phy_type : For multi port host usb controllers, should be one of
|
||||
"ulpi", or "serial". For dual role usb controllers, should be
|
||||
one of "ulpi", "utmi", "utmi_wide", or "serial".
|
||||
- reg : Offset and length of the register set for the device
|
||||
- port0 : boolean; if defined, indicates port0 is connected for
|
||||
fsl-usb2-mph compatible controllers. Either this property or
|
||||
"port1" (or both) must be defined for "fsl-usb2-mph" compatible
|
||||
controllers.
|
||||
- port1 : boolean; if defined, indicates port1 is connected for
|
||||
fsl-usb2-mph compatible controllers. Either this property or
|
||||
"port0" (or both) must be defined for "fsl-usb2-mph" compatible
|
||||
controllers.
|
||||
|
||||
Recommended properties :
|
||||
- interrupts : <a b> where a is the interrupt number and b is a
|
||||
field that represents an encoding of the sense and level
|
||||
information for the interrupt. This should be encoded based on
|
||||
the information in section 2) depending on the type of interrupt
|
||||
controller you have.
|
||||
- interrupt-parent : the phandle for the interrupt controller that
|
||||
services interrupts for this device.
|
||||
|
||||
Example multi port host usb controller device node :
|
||||
usb@22000 {
|
||||
device_type = "usb";
|
||||
compatible = "fsl-usb2-mph";
|
||||
reg = <22000 1000>;
|
||||
#address-cells = <1>;
|
||||
#size-cells = <0>;
|
||||
interrupt-parent = <700>;
|
||||
interrupts = <27 1>;
|
||||
phy_type = "ulpi";
|
||||
port0;
|
||||
port1;
|
||||
};
|
||||
|
||||
Example dual role usb controller device node :
|
||||
usb@23000 {
|
||||
device_type = "usb";
|
||||
compatible = "fsl-usb2-dr";
|
||||
reg = <23000 1000>;
|
||||
#address-cells = <1>;
|
||||
#size-cells = <0>;
|
||||
interrupt-parent = <700>;
|
||||
interrupts = <26 1>;
|
||||
phy = "ulpi";
|
||||
};
|
||||
|
||||
|
||||
More devices will be defined as this spec matures.
