Keep it always enabled, and mark > it boot-on so that the firmware, e.g. U-Boot, enables it at boot, I believe this "mark it boot-on so that the firmware, e.g. U-Boot, enables it at boot" sentence is a bit misleading. AFAIK, u-boot does not parse the kernel dtb to see which regulators need to be enabled. The 'regulator-boot-on' property in kernel dtb regulator node simply indicates that this regulator was left ON by the bootloader (see Documentation/devicetree/bindings/regulator/regulator.yaml). If your goal is to have the regulator enabled by u-boot, I believe you need to add that in u-boot dtb as well. Consider updating the commit messages on both patches accordingly. -- Thanks, Laurentiu
