The Versatile board can be equipped with a interface board just named "IB2". This was created in the early 2000s for prototyping GSM candybar phone form factor products. The IB2 board contains: - Cascaded interrupt controller - Enfora Enabler GSM0308 quad-band module with antenna and separate audio jack - Keypad with joystick - Sanyo 2.5" color display - A 28-pin connector for mounting a camera This adds a DTS file for the combination of the Versatile AB with an IB2 daughterboard mounted, making the LED blink and making the system controller available for drivers, such as the panel driver. The device tree bindings already exist in Documentation/devicetree/bindings/arm/arm-boards.
