dt-bindings: Consolidate ChipIdea USB ci13xxx bindings 



Combine the ChipIdea USB binding into a single document to reduce
duplication and fragmentation. This marks use of the old PHY bindings as
deprecated. Future compatible bindings should use generic PHY binding.

* Freescale i.MX ci13xxx usb controllers



Required properties:

- compatible: Should be "fsl,imx27-usb"

- reg: Should contain registers location and length

- interrupts: Should contain controller interrupt

- fsl,usbphy: phandle of usb phy that connects to the port



Recommended properies:

- phy_type: the type of the phy connected to the core. Should be one

  of "utmi", "utmi_wide", "ulpi", "serial" or "hsic". Without this

  property the PORTSC register won't be touched

- dr_mode: One of "host", "peripheral" or "otg". Defaults to "otg"



Optional properties:

- fsl,usbmisc: phandler of non-core register device, with one argument

  that indicate usb controller index

- vbus-supply: regulator for vbus

- disable-over-current: disable over current detect

- external-vbus-divider: enables off-chip resistor divider for Vbus

- maximum-speed: limit the maximum connection speed to "full-speed".

- tpl-support: TPL (Targeted Peripheral List) feature for targeted hosts



Examples:

usb@02184000 { /* USB OTG */

	compatible = "fsl,imx6q-usb", "fsl,imx27-usb";

	reg = <0x02184000 0x200>;

	interrupts = <0 43 0x04>;

	fsl,usbphy = <&usbphy1>;

	fsl,usbmisc = <&usbmisc 0>;

	disable-over-current;

	external-vbus-divider;

	maximum-speed = "full-speed";

	tpl-support;

};

Qualcomm CI13xxx (Chipidea) USB controllers



Required properties:

- compatible:   should contain "qcom,ci-hdrc"

- reg:          offset and length of the register set in the memory map

- interrupts:   interrupt-specifier for the controller interrupt.

- usb-phy:      phandle for the PHY device

- dr_mode:      Should be "peripheral"



Examples:

	gadget@f9a55000 {

		compatible = "qcom,ci-hdrc";

		reg = <0xf9a55000 0x400>;

		dr_mode = "peripheral";

		interrupts = <0 134 0>;

		usb-phy = <&usbphy0>;

* USB2 ChipIdea USB controller for ci13xxx



Required properties:

- compatible: should be "chipidea,usb2"

- compatible: should be one of:

	"fsl,imx27-usb"

	"lsi,zevio-usb"

	"qcom,ci-hdrc"

	"chipidea,usb2"

- reg: base address and length of the registers

- interrupts: interrupt for the USB controller



Recommended properies:

- phy_type: the type of the phy connected to the core. Should be one

  of "utmi", "utmi_wide", "ulpi", "serial" or "hsic". Without this

  property the PORTSC register won't be touched.

- dr_mode: One of "host", "peripheral" or "otg". Defaults to "otg"



Deprecated properties:

- usb-phy:      phandle for the PHY device. Use "phys" instead.

- fsl,usbphy: phandle of usb phy that connects to the port. Use "phys" instead.



Optional properties:

- clocks: reference to the USB clock

- phys: reference to the USB PHY

- phy-names: should be "usb-phy"

- vbus-supply: reference to the VBUS regulator

- maximum-speed: limit the maximum connection speed to "full-speed".

- tpl-support: TPL (Targeted Peripheral List) feature for targeted hosts

- fsl,usbmisc: (FSL only) phandler of non-core register device, with one

  argument that indicate usb controller index

- disable-over-current: (FSL only) disable over current detect

- external-vbus-divider: (FSL only) enables off-chip resistor divider for Vbus

* LSI Zevio USB OTG Controller



Required properties:

- compatible: Should be "lsi,zevio-usb"

Optional properties:

Examples:

		usb0: usb@b0000000 {

			reg = <0xb0000000 0x1000>;

			compatible = "lsi,zevio-usb";

			interrupts = <8>;
