Kernel-4.18.0-80.el8_mxs-usb-phy

• Freescale MXS USB Phy Device

Required properties:

• compatible: should contain:
  • “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,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:

• fsl,tx-cal-45-dn-ohms: Integer [30-55]. Resistance (in ohms) of switchable
  high-speed trimming resistor connected in parallel with the 45 ohm resistor
  that terminates the DN output signal. Default: 45
• fsl,tx-cal-45-dp-ohms: Integer [30-55]. Resistance (in ohms) of switchable
  high-speed trimming resistor connected in parallel with the 45 ohm resistor
  that terminates the DP output signal. Default: 45
• fsl,tx-d-cal: Integer [79-119]. Current trimming value (as a percentage) of
  the 17.78mA TX reference current. Default: 100

Example:
usbphy1: usbphy@20c9000 {
compatible = “fsl,imx6q-usbphy”, “fsl,imx23-usbphy”;
reg = <0x020c9000 0x1000>;
interrupts = <0 44 0x04>;
fsl,anatop = <&anatop>;
};
