* 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,imx7ulp-usbphy" for imx7ulp |
|
* "fsl,imx8dxl-usbphy" for imx8dxl |
|
"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: usb-phy@20c9000 { |
|
compatible = "fsl,imx6q-usbphy", "fsl,imx23-usbphy"; |
|
reg = <0x020c9000 0x1000>; |
|
interrupts = <0 44 0x04>; |
|
fsl,anatop = <&anatop>; |
|
};
