* Freescale i.MX ci13xxx usb controllers
|
|
|
|
Required properties:
|
|
- compatible: Should be "fsl,imx27-usb"
|
|
- reg: Should contain registers location and length
|
|
- interrupts: Should contain controller interrupt
|
|
- fsl,usbphy: phandle of usb phy that connects to the port
|
|
|
|
Recommended properies:
|
|
- phy_type: the type of the phy connected to the core. Should be one
|
|
of "utmi", "utmi_wide", "ulpi", "serial" or "hsic". Without this
|
|
property the PORTSC register won't be touched
|
|
- dr_mode: One of "host", "peripheral" or "otg". Defaults to "otg"
|
|
|
|
Optional properties:
|
|
- fsl,usbmisc: phandler of non-core register device, with one argument
|
|
that indicate usb controller index
|
|
- vbus-supply: regulator for vbus
|
|
- disable-over-current: disable over current detect
|
|
- external-vbus-divider: enables off-chip resistor divider for Vbus
|
|
- maximum-speed: limit the maximum connection speed to "full-speed".
|
|
- tpl-support: TPL (Targeted Peripheral List) feature for targeted hosts
|
|
|
|
Examples:
|
|
usb@02184000 { /* USB OTG */
|
|
compatible = "fsl,imx6q-usb", "fsl,imx27-usb";
|
|
reg = <0x02184000 0x200>;
|
|
interrupts = <0 43 0x04>;
