23Description
24-----------
25
26Versatile Express platform (http://www.arm.com/versatileexpress/) is a
27reference & prototyping system for ARM Ltd. processors. It can be set up
28from a wide range of boards, each of them containing (apart of the main
29chip/FPGA) a number of microcontrollers responsible for platform
30configuration and control. Theses microcontrollers can also monitor the
31board and its environment by a number of internal and external sensors,
32providing information about power lines voltages and currents, board
33temperature and power usage. Some of them also calculate consumed energy
34and provide a cumulative use counter.
35
36The configuration devices are _not_ memory mapped and must be accessed
37via a custom interface, abstracted by the "vexpress_config" API.
38
39As these devices are non-discoverable, they must be described in a Device
40Tree passed to the kernel. Details of the DT binding for them can be found
41in Documentation/devicetree/bindings/hwmon/vexpress.txt.
