-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";
- };
