9  * Implementation notes:
10  * - CCD register address information as well as the calculation to
11  *   convert raw register values is from https://github.com/ocerman/zenpower.
12  *   The information is not confirmed from chip datasheets, but experiments
13  *   suggest that it provides reasonable temperature values.
14  * - Register addresses to read chip voltage and current are also from
15  *   https://github.com/ocerman/zenpower, and not confirmed from chip
16  *   datasheets. Current calibration is board specific and not typically
17  *   shared by board vendors. For this reason, current values are
18  *   normalized to report 1A/LSB for core current and and 0.25A/LSB for SoC
19  *   current. Reported values can be adjusted using the sensors configuration
20  *   file.
