+CE4100 Device Tree Bindings
+---------------------------
+
+The CE4100 SoC uses for in core peripherals the following compatible
+format: <vendor>,<chip>-<device>.
+Many of the "generic" devices like HPET or IO APIC have the ce4100
+name in their compatible property because they first appeared in this
+SoC.
+
+The CPU nodes
+-------------
+
+	cpus {
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		cpu@0 {
+			device_type = "cpu";
+			compatible = "intel,ce4100";
+			reg = <0x00>;
+		};
+
+		cpu@2 {
+			device_type = "cpu";
+			compatible = "intel,ce4100";
+			reg = <0x02>;
+		};
+	};
+
+A "cpu" node describes one logical processor (hardware thread).
+
+Required properties:
+
+- device_type
+	Device type, must be "cpu".
+
+- reg
+	Local APIC ID, the unique number assigned to each processor by
+	system hardware.
+
+The SoC node
+------------
+
+This node describes the in-core peripherals. Required property:
+  compatible = "intel,ce4100-cp";
+
+The PCI node
+------------
+This node describes the PCI bus on the SoC. Its property should be
+  compatible = "intel,ce4100-pci", "pci";
+
+If the OS is using the IO-APIC for interrupt routing then the reported
+interrupt numbers for devices is no longer true. In order to obtain the
+correct interrupt number, the child node which represents the device has
+to contain the interrupt property. Besides the interrupt property it has
+to contain at least the reg property containing the PCI bus address and
+compatible property according to "PCI Bus Binding Revision 2.1".
