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>;
