+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 {

+ reg = <0x4a062000 0x1000>;
