0001 * Freescale MXS USB Phy Device
0002 
0003 Required properties:
0004 - compatible: should contain:
0005         * "fsl,imx23-usbphy" for imx23 and imx28
0006         * "fsl,imx6q-usbphy" for imx6dq and imx6dl
0007         * "fsl,imx6sl-usbphy" for imx6sl
0008         * "fsl,vf610-usbphy" for Vybrid vf610
0009         * "fsl,imx6sx-usbphy" for imx6sx
0010         * "fsl,imx7ulp-usbphy" for imx7ulp
0011         * "fsl,imx8dxl-usbphy" for imx8dxl
0012   "fsl,imx23-usbphy" is still a fallback for other strings
0013 - reg: Should contain registers location and length
0014 - interrupts: Should contain phy interrupt
0015 - fsl,anatop: phandle for anatop register, it is only for imx6 SoC series
0016 
0017 Optional properties:
0018 - fsl,tx-cal-45-dn-ohms: Integer [30-55]. Resistance (in ohms) of switchable
0019   high-speed trimming resistor connected in parallel with the 45 ohm resistor
0020   that terminates the DN output signal. Default: 45
0021 - fsl,tx-cal-45-dp-ohms: Integer [30-55]. Resistance (in ohms) of switchable
0022   high-speed trimming resistor connected in parallel with the 45 ohm resistor
0023   that terminates the DP output signal. Default: 45
0024 - fsl,tx-d-cal: Integer [79-119]. Current trimming value (as a percentage) of
0025   the 17.78mA TX reference current. Default: 100
0026 
0027 Example:
0028 usbphy1: usb-phy@20c9000 {
0029         compatible = "fsl,imx6q-usbphy", "fsl,imx23-usbphy";
0030         reg = <0x020c9000 0x1000>;
0031         interrupts = <0 44 0x04>;
0032         fsl,anatop = <&anatop>;
0033 };
