If anyone has any objections, please let me know. ------------------ From: Sebastian Krzyszkowiak commit 511f76bf1dce5acf8907b65a7d1bc8f7e7c0d637 upstream. The minimal voltage of VDD_SOC sourced from BUCK1 is 0.81V, which is the currently set value. However, BD71837 only guarantees accuracy of ±0.01V, and this still doesn't factor other reasons for actual voltage to slightly drop in, resulting in the possibility of running out of the operational range. Bump the voltage up to 0.85V, which should give enough headroom.
