23  Each regulator is defined using the standard binding for regulators.

45      Boolean, if present disable all unused switch regulators to save power
46      consumption. Attention, ensure that all important regulators
47      (e.g. DDR ref, DDR supply) has set the "regulator-always-on" property.
48      If not present, the switched regulators are always on and can't be
49      disabled. This binding is a workaround to keep backward compatibility
50      with old dtb's which rely on the fact that the switched regulators are
51      always on and don't mark them explicit as "regulator-always-on".

55    description: |
56      if present, configure the PMIC to shutdown all
57      power rails when PMIC_STBY_REQ line is asserted during the power off sequence.
58      Use this option if the SoC should be powered off by external power management
59      IC (PMIC) on PMIC_STBY_REQ signal.
60      As opposite to PMIC_STBY_REQ boards can implement PMIC_ON_REQ signal.
