Baikal-T1 SoC provides an embedded process, voltage and temperature
sensor to monitor an internal SoC environment (chip temperature, supply
voltage and process monitor) and on time detect critical situations,
which may cause the system instability and even damages. The IP-block
is based on the Analog Bits PVT sensor, but is equipped with a
dedicated control wrapper, which provides a MMIO registers-based access
to the sensor core functionality (APB3-bus based) and exposes an
additional functions like thresholds/data ready interrupts, its status
and masks, measurements timeout. All of these is used to create a hwmon
driver being added to the kernel by this commit.
The driver implements support for the hardware monitoring capabilities
of Baikal-T1 process, voltage and temperature sensors. PVT IP-core
consists of one temperature and four voltage sensors, each of which is
implemented as a dedicated hwmon channel config.
The driver can optionally provide the hwmon alarms for each sensor the
PVT controller supports. The alarms functionality is made compile-time
configurable due to the hardware interface implementation peculiarity,
which is connected with an ability to convert data from only one sensor
at a time. Additional limitation is that the controller performs the
thresholds checking synchronously with the data conversion procedure.
Due to these limitations in order to have the hwmon alarms
automatically detected the driver code must switch from one sensor to
another, read converted data and manually check the threshold status
bits. Depending on the measurements timeout settings this design may
cause additional burden on the system performance. By default if the
alarms kernel config is disabled the data conversion is performed by
the driver on demand when read operation is requested via corresponding
_input-file.

Reading the temperature of ATA drives has been supported for years
by userspace tools such as smarttools or hddtemp. The downside of
such tools is that they need to run with super-user privilege, that
the temperatures are not reported by standard tools such as 'sensors'
or 'libsensors', and that drive temperatures are not available for use
in the kernel's thermal subsystem.
This driver solves this problem by adding support for reading the
temperature of ATA drives from the kernel using the hwmon API and
by adding a temperature zone for each drive.
With this driver, the hard disk temperature can be read using the
unprivileged 'sensors' application:
$ sensors drivetemp-scsi-1-0
drivetemp-scsi-1-0
Adapter: SCSI adapter
temp1: +23.0°C
or directly from sysfs:
$ grep . /sys/class/hwmon/hwmon9/{name,temp1_input}
/sys/class/hwmon/hwmon9/name:drivetemp
/sys/class/hwmon/hwmon9/temp1_input:23000
If the drive supports SCT transport and reports temperature limits,
those are reported as well.
drivetemp-scsi-0-0
Adapter: SCSI adapter
temp1: +27.0°C (low = +0.0°C, high = +60.0°C)
(crit low = -41.0°C, crit = +85.0°C)
(lowest = +23.0°C, highest = +34.0°C)
The driver attempts to use SCT Command Transport to read the drive
temperature. If the SCT Command Transport feature set is not available,
or if it does not report the drive temperature, drive temperatures may
be readable through SMART attributes. Since SMART attributes are not well
defined, this method is only used as fallback mechanism.

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.
