If anyone has any objections, please let me know. ------------------ From: Sebastian Krzyszkowiak commit 4cd46ea0eb4504f7f4fea92cb4601c5c9a3e545e upstream. This reverts commit c24a9b698fb02cd0723fa8375abab07f94b97b10. It's been found that there's a significant per-unit variance in accepted supply voltages and the current set still makes some units unstable. Revert back to nominal values.
