+ARM RealView Boards
+-------------------
+The RealView boards cover tailored evaluation boards that are used to explore
+the ARM11 and Cortex A-8 and Cortex A-9 processors.
+
+Required properties (in root node):
+ /* RealView Emulation Baseboard */
+ compatible = "arm,realview-eb";
+ /* RealView Platform Baseboard for ARM1176JZF-S */
+ compatible = "arm,realview-pb1176";
+ /* RealView Platform Baseboard for ARM11 MPCore */
+ compatible = "arm,realview-pb11mp";
+ /* RealView Platform Baseboard for Cortex A-8 */
+ compatible = "arm,realview-pba8";
+ /* RealView Platform Baseboard Explore for Cortex A-9 */
+ compatible = "arm,realview-pbx";
+
+Required nodes:
+
+- soc: some node of the RealView platforms must be the SoC
+ node that contain the SoC-specific devices, withe the compatible
+ string set to one of these tuples:
+ "arm,realview-eb-soc", "simple-bus"
+ "arm,realview-pb1176-soc", "simple-bus"
+ "arm,realview-pb11mp-soc", "simple-bus"
+ "arm,realview-pba8-soc", "simple-bus"
+ "arm,realview-pbx-soc", "simple-bus"
+
+- syscon: some subnode of the RealView SoC node must be a
+ system controller node pointing to the control registers,
+ with the compatible string set to one of these tuples:
+ "arm,realview-eb-syscon", "syscon"
+ "arm,realview-pb1176-syscon", "syscon"
+ "arm,realview-pb11mp-syscon", "syscon"
+ "arm,realview-pba8-syscon", "syscon"
+ "arm,realview-pbx-syscon", "syscon"
+
+ Required properties for the system controller:
+ - regs: the location and size of the system controller registers,
+ one range of 0x1000 bytes.
+
+Example:
+
+/dts-v1/;
+#include <dt-bindings/interrupt-controller/irq.h>
+#include "skeleton.dtsi"
+
+/ {
+ model = "ARM RealView PB1176 with device tree";
+ compatible = "arm,realview-pb1176";
+
+ soc {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ compatible = "arm,realview-pb1176-soc", "simple-bus";
+ ranges;
+
+ syscon: syscon@10000000 {
+ compatible = "arm,realview-syscon", "syscon";
+ reg = <0x10000000 0x1000>;
+ };
+
+ };
+};
