+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"
+
+Optional properties:
+
+- clocks: a list of phandles and clock-specifier pairs, one for each entry in
+  clock-names.
+
+- clock-names: should include:
+  * "usb_tll_hs_usb_ch0_clk" - USB TLL channel 0 clock
+  * "usb_tll_hs_usb_ch1_clk" - USB TLL channel 1 clock
+  * "usb_tll_hs_usb_ch2_clk" - USB TLL channel 2 clock
+
+Example:
+
+       usbhstll: usbhstll@4a062000 {
+               compatible = "ti,usbhs-tll";
+               reg = <0x4a062000 0x1000>;
+               interrupts = <78>;
+               ti,hwmods = "usb_tll_hs";
+         };
