0023 Description
0024 -----------
0025
0026 Versatile Express platform (http://www.arm.com/versatileexpress/) is a
0027 reference & prototyping system for ARM Ltd. processors. It can be set up
0028 from a wide range of boards, each of them containing (apart of the main
0029 chip/FPGA) a number of microcontrollers responsible for platform
0030 configuration and control. Theses microcontrollers can also monitor the
0031 board and its environment by a number of internal and external sensors,
0032 providing information about power lines voltages and currents, board
0033 temperature and power usage. Some of them also calculate consumed energy
0034 and provide a cumulative use counter.
0035
0036 The configuration devices are _not_ memory mapped and must be accessed
0037 via a custom interface, abstracted by the "vexpress_config" API.
0038
0039 As these devices are non-discoverable, they must be described in a Device
0040 Tree passed to the kernel. Details of the DT binding for them can be found
0041 in Documentation/devicetree/bindings/hwmon/vexpress.txt.
