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.

This allows max6650 devices to be referenced in dts as a cooling device.

The pwm value seems duplicated in cooling_dev_state but since pwm goes
through rounding logic into data->dac, it is modified and messes with
the thermal zone state algorithms. It's also better to serve a cache
value, thus avoiding periodic actual i2c traffic.

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.

Reading back the CONFIG register increases an extra I2C
transaction. This's not necessary and could be replaced
with a local variable caching the register settings.

So this patch replaces two readback regmap_read() calls
with a tmp variable.

The OCC driver limits the rate of sending poll commands to the OCC. If a

is rate-limited, the error is invisible to the user. Fix this by storing
