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.
