OMAP HS USB Host TLL (Transceiver-Less Interface)



Required properties:



- compatible : should be "ti,usbhs-tll"

- reg : should contain one register range i.e. start and length

- interrupts : should contain the TLL module's interrupt

- ti,hwmod : must contain "usb_tll_hs"



Example:



	usbhstll: usbhstll@4a062000 {

		compatible = "ti,usbhs-tll";

		reg = <0x4a062000 0x1000>;

		interrupts = <78>;

		ti,hwmods = "usb_tll_hs";

	  };
