* 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>;
|
|
};
