It can be set up +from a wide range of boards, each of them containing (apart of the main +chip/FPGA) a number of microcontrollers responsible for platform +configuration and control. Theses microcontrollers can also monitor the +board and its environment by a number of internal and external sensors, +providing information about power lines voltages and currents, board +temperature and power usage. Some of them also calculate consumed energy +and provide a cumulative use counter. + +The configuration devices are _not_ memory mapped and must be accessed +via a custom interface, abstracted by the "vexpress_config" API. + +As these devices are non-discoverable, they must be described in a Device +Tree passed to the kernel. Details of the DT binding for them can be found +in Documentation/devicetree/bindings/hwmon/vexpress.txt. -- cgit v1.2.3-59-g8ed1b
