+Generic Platform EHCI Controller
+-----------------------------------------------------
+
+Required properties:
+- compatible : "linux,ehci-platform"
+- reg : Should contain 1 register ranges(address and length)
+- interrupts : EHCI controller interrupt
+
+Optional properties:
+- caps-offset : offset to the capabilities register (default = 0)
+- has-tt : controller has transaction translator(s).
+- has-synopsys-hc-bug : controller has the synopsys hc bug
+- no-io-watchdog : controller does not need io watchdog
+
+- big-endian : descriptors and registers are both big endian. This
+  is the equivalent of specifying big-endian-desc and big-endian-regs.
+OR
+- big-endian-desc : descriptors are in big-endian format
+- big-endian-regs : mmio is in big-endian format
+
+Example:
+	ehci at d8007c00 {
+		compatible = "ehci-platform";
+		reg = <0xd8007c00 0x200>;
+		interrupts = <43>;
+		has-tt;
+	};
