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
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
