The Congatec Board Controller has some voltage, current, temperature
and fan sensors.
This series adds an hwmon driver to enable the support.

This series is based on linux-next (commit
1ffec08567f426a1c593e038cadc61bdc38cb467) as the MFD driver is not yet
available in the main tree.

The sensors support has been tested on the conga-SA7 board with a
conga-SEVAL board.

Note that the Board Controller returns two unknown sensors, which causes
two warnings. These unknown sensors are not defined in the driver provided
by Congatec.

cgbc-hwmon cgbc-hwmon: Board Controller returned an unknown sensor (type=2, id=17), ignore it
cgbc-hwmon cgbc-hwmon: Board Controller returned an unknown sensor (type=1, id=10), ignore it

Best Regards,

Thomas
