-description: |
-  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. Its internal structure is depicted on the next
-  diagram:

-  This bindings describes the external Baikal-T1 PVT control interfaces
-  like MMIO registers space, interrupt request number and clocks source.
-  These are then used by the corresponding hwmon device driver to
-  implement the sysfs files-based access to the sensors functionality.

-	  Baikal-T1 PVT IP-block provides threshold registers for each
-	  supported sensor. But the corresponding interrupts might be
-	  generated by the thresholds comparator only in synchronization with
-	  a data conversion. Additionally there is only one sensor data can
-	  be converted at a time. All of these makes the interface impossible
-	  to be used for the hwmon alarms implementation without periodic
-	  switch between the PVT sensors. By default the data conversion is
-	  performed on demand from the user-space. If this config is enabled
-	  the data conversion will be periodically performed and the data will be
-	  saved in the internal driver cache.
