1 * Freescale i.MX ci13xxx usb controllers 2 3 Required properties: 4 - compatible: Should be "fsl,imx27-usb" 5 - reg: Should contain registers location and length 6 - interrupts: Should contain controller interrupt 7 - fsl,usbphy: phandle of usb phy that connects to the port 8 9 Recommended properies: 10 - phy_type: the type of the phy connected to the core. Should be one 11 of "utmi", "utmi_wide", "ulpi", "serial" or "hsic". Without this 12 property the PORTSC register won't be touched 13 - dr_mode: One of "host", "peripheral" or "otg". Defaults to "otg" 14 15 Optional properties: 16 - fsl,usbmisc: phandler of non-core register device, with one argument 17 that indicate usb controller index 18 - vbus-supply: regulator for vbus 19 - disable-over-current: disable over current detect 20 - external-vbus-divider: enables off-chip resistor divider for Vbus 21 - maximum-speed: limit the maximum connection speed to "full-speed". 22 - tpl-support: TPL (Targeted Peripheral List) feature for targeted hosts 23 24 Examples: 25 usb@02184000 { /* USB OTG */ 26 compatible = "fsl,imx6q-usb", "fsl,imx27-usb"; 27 reg = <0x02184000 0x200>; 28 interrupts = <0 43 0x04>; 29 fsl,usbphy = <&usbphy1>; 30 fsl,usbmisc = <&usbmisc 0>; 31 disable-over-current; 32 external-vbus-divider; 33 maximum-speed = "full-speed"; 34 tpl-support; 35 };
