| 4 | This file contains documentation for the internal USB OTG PHY found |
| 5 | in NXP LPC18xx and LPC43xx SoCs. |

| 7 | Required properties: |
| 8 | - compatible : must be "nxp,lpc1850-usb-otg-phy" |
| 9 | - clocks : must be exactly one entry |
| 10 | See: Documentation/devicetree/bindings/clock/clock-bindings.txt |
| 11 | - #phy-cells : must be 0 for this phy |
| 12 | See: Documentation/devicetree/bindings/phy/phy-bindings.txt |
| 13 | |
| 14 | The phy node must be a child of the creg syscon node. |
| 15 | |
| 16 | Example: |
| 17 | creg: syscon@40043000 { |
| 18 | compatible = "nxp,lpc1850-creg", "syscon", "simple-mfd"; |
| 19 | reg = <0x40043000 0x1000>; |
| 20 | |
| 21 | usb0_otg_phy: phy { |
| 22 | compatible = "nxp,lpc1850-usb-otg-phy"; |
| 23 | clocks = <&ccu1 CLK_USB0>; |
| 24 | #phy-cells = <0>; |
| 25 | }; |
| 26 | }; |
