Iker Perez del Palomar Sustatxa 39abe9d88b hwmon: (lm75) Add support for TMP75B
The TMP75B has a different control register, supports 12-bit
resolution and the default conversion rate is 37 Hz.

Mauro Carvalho Chehab f786dbbe6f docs: hwmon: remove the extension from .rst files
On almost all places, we're including ReST files without the
extension.

Let's remove the extension here	as well, in order to use just
one standard.

Mauro Carvalho Chehab e57695e772 docs: hwmon: convert three docs to ReST format
Those three new drivers were missed on the initial conversion
to ReST format. So:

- Rename them to .rst;
- Add them to the hwmon index.rst index;
- add some blank lines at the "Supported systems:" part, in
  order to allow Sphinx to properly identify new lines,
  suppressing warnings and avoid it to output some random
  lines in bold;
- When multiple authors are involved, change the authors
  part to a list, in order to avoid adding blank lines.
- adjust the table cells (one of the tables seemed to be
  assuming that tab is 4 positions instead of 8) and add
  the table markup.
- be sure that the section markups have the same number of
  characters as the section title.

Nicolin Chen 023912dbb8 hwmon: (ina3221) Add voltage conversion time settings
The CONFIG register has two 3-bit fields for conversion time
settings of Bus-voltage and Shunt-voltage, respectively. The
conversion settings, along with averaging mode, allow users
to optimize available timing requirement.

This patch adds an 'update_interval' sysfs node through the
hwmon_chip_info of hwmon core. It reflects a total hardware
conversion time:
    samples * channels * (Bus + Shunt conversion times)

Though INA3221 supports different conversion time setups for
Bus and Shunt voltages, this patch only adds the support of
a unified setting for both conversion times, by dividing the
conversion time into two equal values.

Chris Packham f1af93216c hwmon: (adt7475) document mapping of sysfs entries to inputs
As per the usual standard with hwmon drivers the mapping to sysfs
entries follows the register map of the device e.g. in0_input
corresponds to the register 0x20, in1_input corresponds to 0x21 etc.

Hardware designers tend to work with input pins instead of registers
which is where things start to get confusing. A hardware designer might
say "the 1.5V rail is connected to the VCCP pin" leaving the software
designer none the wiser as to which of the sysfs entries should be
associated with the label "1.5V".

Try to bridge the gap by documenting the mapping of sysfs entries to
the corresponding pins. This should allow someone to create a
configuration file or other mapping without needing to dive into the
code and ADT datasheets.

The ADM series of hotswap controllers support extending
the current measurement range by using a sensing resistor
value other than the typical 1 mOhm. For example, using a 0.5 mOhm
sensing resistor doubles the maximal current can be measured.

Current driver assumes a shunt resistor value of 1 mOhm in calculation,
meaning for other resistor values, hwmon will report scaled
current/power measurements. This patch parses device tree parameter
"shunt-resistor-micro-ohms", if there is one.

Nicolin Chen a9e9dd9c6d hwmon: (ina3221) Read channel input source info from DT
An ina3221 chip has three input ports. Each port is used
to measure the voltage and current of its input source.

The DT binding now has defined bindings for their input
sources, so the driver should read these information and
handle accordingly.

This patch adds a new structure of input source specific
information including input source label, shunt resistor
value and its connection status. It exposes these labels
via in[123]_label sysfs nodes upon available, and also
disables those channels where there are no input source
being connected. Meanwhile, it also adds in[123]_enable
sysfs nodes for users to get control of three channels,
and returns -ENODATA code for any sensor read according
to hwmon ABI.
