Subject: [PATCH 0/2] Enable sensors support for the Congatec Board
 Controller

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
