Subject: [PATCH v4 0/2] Enable sensors support for the Congatec Board
 Controller

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

The series was rebased on v6.14-rc1.
A typo was fixed in the Kconfig, and the description improved.
The documentation file Documentation/hwmon/cgbc-hwmon.rst was added.

Regards,

Thomas

Changes in v4:
- Rebased on v6.14-rc1.
- Add the documentation for this driver.
- In Kconfig, fix a typo and improve the description
- Link to v3: https://lore.kernel.org/r/20241115-congatec-board-controller-hwmon-v3-0-1c45637c8266@bootlin.com

Changes in v3:
- remove the cgbc_hwmon_compute_curr_channel() macro.
- Link to v2: https://lore.kernel.org/r/20241108-congatec-board-controller-hwmon-v2-0-16e337398527@bootlin.com

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.
- Link to v1: https://lore.kernel.org/r/20241104-congatec-board-controller-hwmon-v1-0-871e4cd59d8e@bootlin.com
