[PATCH v2 01/15] arm64: dts: imx8mm-phycore-som: Keep LDO3 on in suspend
From: Andrej Picej
Date: Mon Dec 02 2024 - 02:21:40 EST
From: Teresa Remmet <t.remmet@xxxxxxxxx>
LDO3 is also used as switch for enabling VDD_3V3_S and need to
be kept on during suspend. Disabling this can lead to an unwanted
reset during resume.
Set LDO3 to 2,5V as the voltage should be fix.
