The thermal management system of sama7d65 includes
- Temperature sensor as a part of ADC channel
- Temperature calibration data retreived from the OTP memory for
improved accuracy of the readings
- DVFS implementation
- And finally a thermal system with DVFS as cooling cell.
This patch series adds support for the following
- New and improved version of the OTP driver
- Adaptation of the above in existing DT, DT doc and ADC driver
- DVFS, OTP, ADC, Thermal system support in DT of new sama7d65
