16	Description
17	-----------
18	
19	Versatile Express platform (http://www.arm.com/versatileexpress/) is a
20	reference & prototyping system for ARM Ltd. processors. It can be set up
21	from a wide range of boards, each of them containing (apart of the main
22	chip/FPGA) a number of microcontrollers responsible for platform
23	configuration and control. Theses microcontrollers can also monitor the
24	board and its environment by a number of internal and external sensors,
25	providing information about power lines voltages and currents, board
26	temperature and power usage. Some of them also calculate consumed energy
27	and provide a cumulative use counter.
28	
29	The configuration devices are _not_ memory mapped and must be accessed
30	via a custom interface, abstracted by the "vexpress_config" API.
31	
32	As these devices are non-discoverable, they must be described in a Device
33	Tree passed to the kernel. Details of the DT binding for them can be found
34	in Documentation/devicetree/bindings/hwmon/vexpress.txt.
