 | 	* "fsl,imx23-usbphy" for imx23 and imx28 | 
 | 	* "fsl,imx6q-usbphy" for imx6dq and imx6dl | 
 | 	* "fsl,imx6sl-usbphy" for imx6sl | 
 | 	* "fsl,vf610-usbphy" for Vybrid vf610 | 
 | 	* "fsl,imx6sx-usbphy" for imx6sx | 
 | 	* "fsl,imx6ul-usbphy" for imx6ul | 
 |   "fsl,imx23-usbphy" is still a fallback for other strings | 
 | - reg: Should contain registers location and length | 
 | - interrupts: Should contain phy interrupt | 
 | - fsl,anatop: phandle for anatop register, it is only for imx6 SoC series | 
 |  | 
 | Optional properties: | 
 | - tx-d-cal: Try to adjust this value to improve signal quality, and pass | 
 |   USB Certification, the value is from 0x0 to 0xf, and the register offset |
