+ARM Integrator/AP (Application Platform) and Integrator/CP (Compact Platform)
+-----------------------------------------------------------------------------
+ARM's oldest Linux-supported platform with connectors for different core
+tiles of ARMv4, ARMv5 and ARMv6 type.
+
+Required properties (in root node):
+ compatible = "arm,integrator-ap"; /* Application Platform */
+ compatible = "arm,integrator-cp"; /* Compact Platform */
+
+FPGA type interrupt controllers, see the versatile-fpga-irq binding doc.
+
+Required nodes:
+
+- core-module: the root node to the Integrator platforms must have
+ a core-module with regs and the compatible string
+ "arm,core-module-integrator"
+- external-bus-interface: the root node to the Integrator platforms
+ must have an external bus interface with regs and the
+ compatible-string "arm,external-bus-interface"
+
+ Required properties for the core module:
+ - regs: the location and size of the core module registers, one
+ range of 0x200 bytes.
+
+- syscon: the root node of the Integrator platforms must have a
+ system controller node pointing to the control registers,
+ with the compatible string
+ "arm,integrator-ap-syscon"
+ "arm,integrator-cp-syscon"
+ respectively.
+
+ Required properties for the system controller:
+ - regs: the location and size of the system controller registers,
+ one range of 0x100 bytes.
+
+ Required properties for the AP system controller:
+ - interrupts: the AP syscon node must include the logical module
+ interrupts, stated in order of module instance <module 0>,
+ <module 1>, <module 2> ... for the CP system controller this
+ is not required not of any use.

+
+ARM Versatile Application and Platform Baseboards
+-------------------------------------------------
+ARM's development hardware platform with connectors for customizable
+core tiles. The hardware configuration of the Versatile boards is
+highly customizable.
+
+Required properties (in root node):
+ compatible = "arm,versatile-ab"; /* Application baseboard */
+ compatible = "arm,versatile-pb"; /* Platform baseboard */
+
+Interrupt controllers:
+- VIC required properties:
+ compatible = "arm,versatile-vic";
+ interrupt-controller;
+ #interrupt-cells = <1>;
+
+- SIC required properties:
+ compatible = "arm,versatile-sic";
+ interrupt-controller;
+ #interrupt-cells = <1>;
+
+Required nodes:
+
+- core-module: the root node to the Versatile platforms must have
+ a core-module with regs and the compatible strings
+ "arm,core-module-versatile", "syscon"
+
+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>;
