From b6af6a5af6265696a4b541c478cb9c5e96bddbba Mon Sep 17 00:00:00 2001 From: Teresa Remmet Date: Tue, 18 Feb 2025 08:41:42 +0100 Subject: [PATCH] arm64: dts: imx8mm-phycore-som: Keep LDO3 on in suspend 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.
