Add support for the Congatec Board Controller. This controller exposes temperature, voltage, current and fan sensors. The available sensors list cannot be predicted. Some sensors can be present or not, depending the system. The driver has an internal list of all possible sensors, for all Congatec boards. The Board Controller gives to the driver its sensors list, and their status (active or not).

Description
|
|
-----------
|
|
|
|
This driver enables monitoring support for the Congatec Board Controller.
|
|
This controller is embedded on the x86 SoMs of Congatec.

|
|
|
Sysfs entries
|
|
-------------
|
|
|
|
The following sysfs entries list contains all sensors defined in the Board
|
|
Controller. The available sensors in sysfs depend on the SoM and the
|
|
system.
