8 title: Baikal-T1 PVT Sensor
11   - Serge Semin <fancer.lancer@gmail.com>
14   Baikal-T1 SoC provides an embedded process, voltage and temperature
15   sensor to monitor an internal SoC environment (chip temperature, supply
17   which may cause the system instability and even damages. The IP-block
18   is based on the Analog Bits PVT sensor, but is equipped with a dedicated
19   control wrapper, which provides a MMIO registers-based access to the
20   sensor core functionality (APB3-bus based) and exposes an additional
25      Analog Bits core                     Bakal-T1 PVT control block
