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

| description: |
| should be "ldo1", ..., "ldo5", "buck1", ..., "buck5" and "ldolpsr" |
| for ldolpsr regulator, "ldodvref" for ldodvref reglator. |

| description: |
| GPIO used to control ldo4 state (when ldo4 is controlled by GPIO). |
| |
| rohm,dvs-run-voltage: |
| description: |
| PMIC "RUN" state voltage in uV when PMIC HW states are used. See |
| comments below for bucks/LDOs which support this. 0 means |
| regulator should be disabled at RUN state. |
| $ref: "/schemas/types.yaml#/definitions/uint32" |
| minimum: 0 |
| maximum: 3300000 |
| |
| rohm,dvs-snvs-voltage: |
| description: |
| Whether to keep regulator enabled at "SNVS" state or not. |
| 0 means regulator should be disabled at SNVS state, non zero voltage |
| keeps regulator enabled. BD71815 does not change voltage level |
| when PMIC transitions to SNVS.SNVS voltage depends on the previous |
| state (from which the PMIC transitioned to SNVS). |
| $ref: "/schemas/types.yaml#/definitions/uint32" |
| minimum: 0 |
| maximum: 3300000 |
| |
| rohm,dvs-suspend-voltage: |
| description: |
| PMIC "SUSPEND" state voltage in uV when PMIC HW states are used. See |
| comments below for bucks/LDOs which support this. 0 means |
| regulator should be disabled at SUSPEND state. |
| $ref: "/schemas/types.yaml#/definitions/uint32" |
| minimum: 0 |
| maximum: 3300000 |
| |
| rohm,dvs-lpsr-voltage: |
| description: |
| PMIC "LPSR" state voltage in uV when PMIC HW states are used. See |
| comments below for bucks/LDOs which support this. 0 means |
| regulator should be disabled at LPSR state. |
| $ref: "/schemas/types.yaml#/definitions/uint32" |
| minimum: 0 |
| maximum: 3300000 |
| |
| # Bucks 1 and 2 support giving separate voltages for operational states |
| # (RUN /CLEAN according to data-sheet) and non operational states |
| # (LPSR/SUSPEND). The voltage is automatically changed when HW |
| # state changes. Omitting these properties from bucks 1 and 2 leave |
| # buck voltages to not be toggled by HW state. Enable status may still |
| # be toggled by state changes depending on HW default settings. |
| # |
| # Bucks 3-5 and ldos 1-5 support setting the RUN state voltage here. |
| # Given RUN voltage is used at all states if regulator is enabled at |
| # given state. |
| # Values given for other states are regarded as enable/disable at |
| # given state (see below). |
| # |
| # All regulators except WLED support specifying enable/disable status |
| # for each of the HW states (RUN/SNVS/SUSPEND/LPSR). HW defaults can |
| # be overridden by setting voltage to 0 (regulator disabled at given |
| # state) or non-zero (regulator enabled at given state). Please note |
| # that setting non zero voltages for bucks 1/2 will also enable voltage |
| # changes according to state change. |
