Atmel SOC USB controllers



EHCI



Required properties:

 - compatible: Should be "atmel,at91sam9g45-ehci" for USB controllers

   used in host mode.

 - reg: Address and length of the register set for the device

 - interrupts: Should contain ehci interrupt

 - clocks: Should reference the peripheral and the UTMI clocks

 - clock-names: Should contain two strings

		"ehci_clk" for the peripheral clock

		"usb_clk" for the UTMI clock



Optional properties:

 - phy_type : For multi port host USB controllers, should be one of

   "utmi", or "hsic".
