| * 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 |
| - imx-usb-charger-detection: enable imx usb charger detect function, |
| only set it when the user wants SoC usb charger detection capabilities. |
| If the user wants to use charger IC's usb charger detection capabilities, |
| please do not set it. |
| - fsl,anatop: phandle for anatop module, anatop module is only existed |
| at imx6 SoC series. |
| - pinctrl-names: for names of hsic pin group |
| - pinctrl-0: hsic "idle" pin group |
| - pinctrl-1: hsic "active" pin group |
| - osc-clkgate-delay: the delay between powering up the xtal 24MHz clock |
| and release the clock to the digital logic inside the analog block, |
| 0 <= osc-clkgate-delay <= 7. |
| - maximum-speed: limit the maximum connection speed to "full-speed". |
| - tpl-support: TPL (Targeted Peripheral List) feature for targeted hosts |
| - phy-clkgate-delay-us: the delay time(us) between putting phy into low power |
| mode and gate phy clock. |
| |
| Examples: |
| usb@02184000 { /* USB OTG */ |
| compatible = "fsl,imx6q-usb", "fsl,imx27-usb"; |

| interrupts = <0 43 0x04>; |
| fsl,usbphy = <&usbphy1>; |
| fsl,usbmisc = <&usbmisc 0>; |
| disable-over-current; |
| external-vbus-divider; |
| imx-usb-charger-detection; |
| fsl,anatop = <&anatop>; |
| pinctrl-names = "idle", "active"; |
| pinctrl-0 = <&pinctrl_usbh2_1>; |
| pinctrl-1 = <&pinctrl_usbh2_2>; |
| osc-clkgate-delay = <0x3>; |
| maximum-speed = "full-speed"; |
| tpl-support; |
| phy-clkgate-delay-us = <400>; |
