-* 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 [35-54]. 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 [35-54]. 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 {

Convert the binding to DT schema format. Besides, this also add other optional properties not contained in txt file. Signed-off-by: Xu Yang <xu.yang_2@nxp.com> --- Changes in v2: - change filename to fsl,mxs-usbphy.yaml - add other optional properties - narrow fsl,anatop to imx6 - use additionalProperties Changes in v3: - fix indentation - add clocks property to example --- .../bindings/phy/fsl,mxs-usbphy.yaml | 130 ++++++++++++++++++ .../devicetree/bindings/phy/mxs-usb-phy.txt | 33 ----- 2 files changed, 130 insertions(+), 33 deletions(-) create mode 100644 Documentation/devicetree/bindings/phy/fsl,mxs-usbphy.yaml delete mode 100644 Documentation/devicetree/bindings/phy/mxs-usb-phy.txt
