6.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dmitry Baryshkov <dmitry.baryshkov@xxxxxxxxxx>
[ Upstream commit d6c6b85bf5582bbe2efefa9a083178b5f7eef439 ]
The L9A regulator is used to further control voltage regulators on the
board. It can be used to disable VBAT_mains, 1.8V, 3.3V, 5V rails). Make
sure that is stays always on to prevent undervolting of these volage
rails.
