17 The Maxim MAX77686 provides 10 high-efficiency Buck and 32 Low-DropOut (LDO)
23 Certain regulators support "regulator-initial-mode" and "regulator-mode".
24 The valid modes list is defined in the dt-bindings/regulator/maxim,max77802.h
26 1 - Normal regulator voltage output mode.
27 3 - Low Power which reduces the quiescent current down to only 1uA

10 To check if hibernation works, you can try to hibernate in the "reboot" mode::
21 modes causes the PM core to skip some platform-related callbacks which on ACPI

29 which is the default and recommended mode of hibernation.
31 Unfortunately, the "platform" mode of hibernation does not work on some systems
