Subject: [PATCH v2 0/2] Enable sensors support for the Congatec Board
 Controller

This is the second iteration of this series which enables sensors support
for the Congatec Board Controller.

The main change in the hwmon driver is that now a channel id always refers
to the same sensor. So in0 is always "CPU voltage", temp1 is always "CPU
Temperature", ...

Regards,

Thomas

Changes in v2:
- hwmon: use unsigned int type instead of u8 in struct cgbc_hwmon_sensor
  and struct cgbc_hwmon_data.
- hwmon: in cgbc_hwmon_probe_sensors() no need to request data for the
  first sensor as the Board Controller returns data of the first sensors
  with the number of sensors.
- hwmon: fix typos in comments and improve them.
- hwmon: remove dead code in cgbc_hwmon_read() and in
  cgbc_hwmon_read_string() (deadcode was the 'return -ENODEV').
- hwmon: remove useless platform_set_drvdata().
- hwmon: channel id always refers to the same sensor.
- hwmon: add a enum cgbc_sensor_types.
