13  This module is part of the ROHM BD718215 MFD device. For more details
14  see Documentation/devicetree/bindings/mfd/rohm,bd71815-pmic.yaml.
15
16  The regulator controller is represented as a sub-node of the PMIC node
17  on the device tree.
18
19  The valid names for BD71815 regulator nodes are
20  buck1, buck2, buck3, buck4, buck5,
21  ldo1, ldo2, ldo3, ldo4, ldo5,
22  ldodvref, ldolpsr, wled

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

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