Subject: [PATCH 1/1] dt-bindings: usb: Convert fsl-usb to yaml
Convert fsl-usb binding doc to yaml format.
Additional change:
- Remove port0 and port1 from required list.
- Use common usb-drd.yaml for dr_mode property
- Keep two difference examples.
- Add interrupts to required property list.
- Remove #address-cells and #size-cells in example.
- Use predefined irq type macro.

-Freescale SOC USB controllers
-
-The device node for a USB controller that is part of a Freescale
-SOC is as described in the document "Open Firmware Recommended
-Practice : Universal Serial Bus" with the following modifications
-and additions :
-
-Required properties :
- - compatible : Should be "fsl-usb2-mph" for multi port host USB
- controllers, or "fsl-usb2-dr" for dual role USB controllers
- or "fsl,mpc5121-usb2-dr" for dual role USB controllers of MPC5121.
- Wherever applicable, the IP version of the USB controller should
- also be mentioned (for eg. fsl-usb2-dr-v2.2 for bsc9132).
- - phy_type : For multi port host USB controllers, should be one of
- "ulpi", or "serial". For dual role USB controllers, should be
- one of "ulpi", "utmi", "utmi_wide", or "serial".
- - reg : Offset and length of the register set for the device
- - port0 : boolean; if defined, indicates port0 is connected for
- fsl-usb2-mph compatible controllers. Either this property or
- "port1" (or both) must be defined for "fsl-usb2-mph" compatible
- controllers.
- - port1 : boolean; if defined, indicates port1 is connected for
- fsl-usb2-mph compatible controllers. Either this property or
- "port0" (or both) must be defined for "fsl-usb2-mph" compatible
- controllers.
- - dr_mode : indicates the working mode for "fsl-usb2-dr" compatible
- controllers. Can be "host", "peripheral", or "otg". Default to
- "host" if not defined for backward compatibility.
-
-Recommended properties :
- - interrupts : <a b> where a is the interrupt number and b is a
- field that represents an encoding of the sense and level
- information for the interrupt. This should be encoded based on
- the information in section 2) depending on the type of interrupt
- controller you have.
-
-Optional properties :
- - fsl,invert-drvvbus : boolean; for MPC5121 USB0 only. Indicates the
- port power polarity of internal PHY signal DRVVBUS is inverted.
- - fsl,invert-pwr-fault : boolean; for MPC5121 USB0 only. Indicates
- the PWR_FAULT signal polarity is inverted.
-
-Example multi port host USB controller device node :
- usb@...00 {
- compatible = "fsl-usb2-mph";
- reg = <22000 1000>;
- #address-cells = <1>;
- #size-cells = <0>;
- interrupt-parent = <700>;
- interrupts = <27 1>;
- phy_type = "ulpi";
- port0;
- port1;
- };
-
-Example dual role USB controller device node :
- usb@...00 {
- compatible = "fsl-usb2-dr";
- reg = <23000 1000>;
- #address-cells = <1>;
- #size-cells = <0>;
- interrupt-parent = <700>;
- interrupts = <26 1>;
- dr_mode = "otg";
- phy = "ulpi";
- };
-
-Example dual role USB controller device node for MPC5121ADS:
-
- usb@...0 {
- compatible = "fsl,mpc5121-usb2-dr";
- reg = <0x4000 0x1000>;
- #address-cells = <1>;
- #size-cells = <0>;
- interrupt-parent = < &ipic >;
- interrupts = <44 0x8>;
- dr_mode = "otg";
- phy_type = "utmi_wide";
- fsl,invert-drvvbus;
- fsl,invert-pwr-fault;
- };
