Merge tag 'docs-5.5a' of git://git.lwn.net/linux

2019-12-02T19:51:02+00:00

Pull Documentation updates from Jonathan Corbet:
 "Here are the main documentation changes for 5.5:

   - Various kerneldoc script enhancements.

   - More RST conversions; those are slowing down as we run out of
     things to convert, but we're a ways from done still.

   - Dan's "maintainer profile entry" work landed at last. Now we just
     need to get maintainers to fill in the profiles...

   - A reworking of the parallel build setup to work better with a
     variety of systems (and to not take over huge systems entirely in
     particular).

   - The MAINTAINERS file is now converted to RST during the build.
     Hopefully nobody ever tries to print this thing, or they will need
     to load a lot of paper.

   - A script and documentation making it easy for maintainers to add
     Link: tags at commit time.

  Also included is the removal of a bunch of spurious CR characters"

dell-smm-hwmon: Add documentation

2019-11-23T04:47:43+00:00

Part of the documentation is taken from the README of the userspace
utils (https://github.com/vitorafsr/i8kutils). The license is GPL-2+
and the author Massimo Dal Zotto is already credited as author of
the module. Therefore there should be no copyright problem.

I also added a paragraph with specific information on the experimental
support for automatic BIOS fan control.

hwmon: Add driver for Texas Instruments TMP512/513 sensor chips.

2019-11-22T05:26:40+00:00

TI's TMP512/513 are I2C/SMBus system monitor chips. These chips
monitor the supply voltage, supply current, power consumption
and provide one local and up to three (TMP513) remote temperature sensors.

It has been tested using a TI TMP513 development kit (TMP513EVM)

hwmon: Add support for ltc2947

2019-11-06T22:37:19+00:00

The ltc2947 is a high precision power and energy monitor with an
internal sense resistor supporting up to +/- 30A. Three internal no
Latency ADCs ensure accurate measurement of voltage and current, while
high-bandwidth analog multiplication of voltage and current provides
accurate power measurement in a wide range of applications. Internal or
external clocking options enable precise charge and energy measurements.

hwmon: (ina3221) Add summation feature support

2019-11-06T22:37:19+00:00

This patch implements the summation feature of INA3221, mainly the
SCC (enabling) and SF (warning flag) bits of MASK_ENABLE register,
INA3221_SHUNT_SUM (summation of shunt voltages) register, and the
INA3221_CRIT_SUM (its critical alert setting) register.

Although the summation feature allows user to select which channels
to be added to the result, as an initial support, this patch simply
selects all channels by default, with one only condition: all shunt
resistor values need to be the same. This is because the summation
of current channels can be only accurately calculated, using shunt
voltage sum register, if all shunt resistors are equivalent.

I need to pick up the independent changes made to
Documentation/core-api/memory-allocation.rst to be able to merge further
work without creating a total mess.

2019-10-02T13:40:29+00:00

When generating documentation output Sphinx
outputs a warning for not including
the page 'inspur-ipsps1.rst' in 'index.rst'.

Assuming this documentation is useful it
should be included in the index.
