1*4882a593Smuzhiyun* Freescale MXS USB Phy Device
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunRequired properties:
4*4882a593Smuzhiyun- compatible: should contain:
5*4882a593Smuzhiyun	* "fsl,imx23-usbphy" for imx23 and imx28
6*4882a593Smuzhiyun	* "fsl,imx6q-usbphy" for imx6dq and imx6dl
7*4882a593Smuzhiyun	* "fsl,imx6sl-usbphy" for imx6sl
8*4882a593Smuzhiyun	* "fsl,vf610-usbphy" for Vybrid vf610
9*4882a593Smuzhiyun	* "fsl,imx6sx-usbphy" for imx6sx
10*4882a593Smuzhiyun	* "fsl,imx7ulp-usbphy" for imx7ulp
11*4882a593Smuzhiyun  "fsl,imx23-usbphy" is still a fallback for other strings
12*4882a593Smuzhiyun- reg: Should contain registers location and length
13*4882a593Smuzhiyun- interrupts: Should contain phy interrupt
14*4882a593Smuzhiyun- fsl,anatop: phandle for anatop register, it is only for imx6 SoC series
15*4882a593Smuzhiyun
16*4882a593SmuzhiyunOptional properties:
17*4882a593Smuzhiyun- fsl,tx-cal-45-dn-ohms: Integer [30-55]. Resistance (in ohms) of switchable
18*4882a593Smuzhiyun  high-speed trimming resistor connected in parallel with the 45 ohm resistor
19*4882a593Smuzhiyun  that terminates the DN output signal. Default: 45
20*4882a593Smuzhiyun- fsl,tx-cal-45-dp-ohms: Integer [30-55]. Resistance (in ohms) of switchable
21*4882a593Smuzhiyun  high-speed trimming resistor connected in parallel with the 45 ohm resistor
22*4882a593Smuzhiyun  that terminates the DP output signal. Default: 45
23*4882a593Smuzhiyun- fsl,tx-d-cal: Integer [79-119]. Current trimming value (as a percentage) of
24*4882a593Smuzhiyun  the 17.78mA TX reference current. Default: 100
