1* Freescale MXS USB Phy Device
2
3Required properties:
4- compatible: should contain:
5	* "fsl,imx23-usbphy" for imx23 and imx28
6	* "fsl,imx6q-usbphy" for imx6dq and imx6dl
7	* "fsl,imx6sl-usbphy" for imx6sl
8	* "fsl,vf610-usbphy" for Vybrid vf610
9	* "fsl,imx6sx-usbphy" for imx6sx
10	* "fsl,imx7ulp-usbphy" for imx7ulp
11	* "fsl,imx8dxl-usbphy" for imx8dxl
12  "fsl,imx23-usbphy" is still a fallback for other strings
13- reg: Should contain registers location and length
14- interrupts: Should contain phy interrupt
15- fsl,anatop: phandle for anatop register, it is only for imx6 SoC series
16
17Optional properties:
18- fsl,tx-cal-45-dn-ohms: Integer [35-54]. Resistance (in ohms) of switchable
19  high-speed trimming resistor connected in parallel with the 45 ohm resistor
20  that terminates the DN output signal. Default: 45
21- fsl,tx-cal-45-dp-ohms: Integer [35-54]. Resistance (in ohms) of switchable
22  high-speed trimming resistor connected in parallel with the 45 ohm resistor
23  that terminates the DP output signal. Default: 45
24- fsl,tx-d-cal: Integer [79-119]. Current trimming value (as a percentage) of
25  the 17.78mA TX reference current. Default: 100
26
27Example:
28usbphy1: usb-phy@20c9000 {
29	compatible = "fsl,imx6q-usbphy", "fsl,imx23-usbphy";
30	reg = <0x020c9000 0x1000>;
31	interrupts = <0 44 0x04>;
32	fsl,anatop = <&anatop>;
33};
