From: Tao Ren <[email protected]>
The patch series adds "bel-pfe" pmbus driver which supports hardware
monitoring for BEL PFE1100 and PFE3000 power supplies.
There are total 2 patches:
- patch #1 adds bel-pfe pmbus driver for BEL PFE1100 and PFE3000 power
supplies.
- patch #2 adds documentation for the bel-pfe pmbus driver.
The driver has been tested on Facebook Wedge40 BMC (with PFE1100) and
Facebook CMM BMC (with PFE3000).

+Kernel driver bel-pfe
+======================
+
+Supported chips:
+
+ * BEL PFE1100
+
+ Prefixes: 'pfe1100'
+
+ Addresses scanned: -
+
+ Datasheet: https://www.belfuse.com/resources/datasheets/powersolutions/ds-bps-pfe1100-12-054xa.pdf

+
+Description
+-----------
+
+This driver supports hardware monitoring for below power supply devices
+which support PMBus Protocol:
+
+ * BEL PFE1100
+
+ 1100 Watt AC to DC power-factor-corrected (PFC) power supply.
+ PMBus Communication Manual is not publicly available.
+
+ * BEL PFE3000
+
+ 3000 Watt AC/DC power-factor-corrected (PFC) and DC-DC power supply.
+ PMBus Communication Manual is not publicly available.
+
+The driver is a client driver to the core PMBus driver. Please see
+Documentation/hwmon/pmbus.rst for details on PMBus client drivers.
+
+
+Usage Notes
+-----------
+
+This driver does not auto-detect devices. You will have to instantiate the
+devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for
+details.
+
+Example: the following will load the driver for an PFE3000 at address 0x20
+on I2C bus #1::
+
+ $ modprobe bel-pfe
+ $ echo pfe3000 0x20 > /sys/bus/i2c/devices/i2c-1/new_device
+
+
+Platform data support
+---------------------
+
+The driver supports standard PMBus driver platform data.
+
+
+Sysfs entries

Applied after adding bel-pfe to index.rst.

Thank you Guenter. I didn't know index.rst needs to be updated; will
do it for my future doc patches.

No worries. This is a result of the effort to convert the documentation
to .rst format, which makes everything a bit more difficult (such as
the need to add new files to the index). I am still getting used to
it myself.
