     13  This module is part of the ROHM BD718215 MFD device. For more details

     16  The regulator controller is represented as a sub-node of the PMIC node
     17  on the device tree.

     19  The valid names for BD71815 regulator nodes are
     20  buck1, buck2, buck3, buck4, buck5,
     21  ldo1, ldo2, ldo3, ldo4, ldo5,

     65          0 means regulator should be disabled at SNVS state, non zero voltage
     66          keeps regulator enabled. BD71815 does not change voltage level
     67          when PMIC transitions to SNVS.SNVS voltage depends on the previous
     68          state (from which the PMIC transitioned to SNVS).

     91        # Bucks 1 and 2 support giving separate voltages for operational states
     92        # (RUN /CLEAN according to data-sheet) and non operational states
     93        # (LPSR/SUSPEND). The voltage is automatically changed when HW
     94        # state changes. Omitting these properties from bucks 1 and 2 leave
     95        # buck voltages to not be toggled by HW state. Enable status may still
     96        # be toggled by state changes depending on HW default settings.
     97        #
     98        # Bucks 3-5 and ldos 1-5 support setting the RUN state voltage here.
     99        # Given RUN voltage is used at all states if regulator is enabled at
    100        # given state.
    101        # Values given for other states are regarded as enable/disable at
    102        # given state (see below).
    103        #
    104        # All regulators except WLED support specifying enable/disable status
    105        # for each of the HW states (RUN/SNVS/SUSPEND/LPSR). HW defaults can
    106        # be overridden by setting voltage to 0 (regulator disabled at given
    107        # state) or non-zero (regulator enabled at given state). Please note
    108        # that setting non zero voltages for bucks 1/2 will also enable voltage
    109        # changes according to state change.
