8 title: Baikal-T1 PVT Sensor
11 - Serge Semin <fancer.lancer@gmail.com>
14 Baikal-T1 SoC provides an embedded process, voltage and temperature
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
