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.
