| USB EHCI controllers | 
 |  | 
 | Required properties: | 
 |   - compatible : should be "generic-ehci". | 
 |   - reg : should contain at least address and length of the standard EHCI | 
 |     register set for the device. Optional platform-dependent registers | 
 |     (debug-port or other) can be also specified here, but only after | 
 |     definition of standard EHCI registers. | 
 |   - interrupts : one EHCI interrupt should be described here. | 
 |  | 
 | Optional properties: | 
 |  - big-endian-regs : boolean, set this for hcds with big-endian registers | 
 |  - big-endian-desc : boolean, set this for hcds with big-endian descriptors | 
 |  - big-endian : boolean, for hcds with big-endian-regs + big-endian-desc | 
 |  - clocks : a list of phandle + clock specifier pairs | 
 |  - phys : phandle + phy specifier pair | 
 |  - phy-names : "usb" | 
 |  | 
 | Example (Sequoia 440EPx): | 
 |     ehci@e0000300 { | 
 | 	   compatible = "ibm,usb-ehci-440epx", "usb-ehci"; | 
 | 	   interrupt-parent = <&UIC0>; | 
 | 	   interrupts = <1a 4>; | 
 | 	   reg = <0 e0000300 90 0 e0000390 70>; | 
 | 	   big-endian; | 
 |    }; | 
 |  | 
 | Example (Allwinner sun4i A10 SoC): | 
 |    ehci0: usb@01c14000 { | 
 | 	   compatible = "allwinner,sun4i-a10-ehci", "generic-ehci"; | 
 | 	   reg = <0x01c14000 0x100>; | 
 | 	   interrupts = <39>; | 
 | 	   clocks = <&ahb_gates 1>; | 
 | 	   phys = <&usbphy 1>; | 
 | 	   phy-names = "usb"; | 
 |    }; |
