| 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 |

| 55 | description: |
| 56 | PMIC "RUN" state voltage in uV when PMIC HW states are used. See |
| 57 | comments below for bucks/LDOs which support this. 0 means |
| 58 | regulator should be disabled at RUN state. |

| 63 | rohm,dvs-snvs-voltage: |
| 64 | description: |
| 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). |

| 75 | description: |
| 76 | PMIC "SUSPEND" state voltage in uV when PMIC HW states are used. See |
| 77 | comments below for bucks/LDOs which support this. 0 means |
| 78 | regulator should be disabled at SUSPEND state. |

| 81 | maximum: 3300000 |

| 83 | rohm,dvs-lpsr-voltage: |
| 84 | description: |
| 85 | PMIC "LPSR" state voltage in uV when PMIC HW states are used. See |
| 86 | comments below for bucks/LDOs which support this. 0 means |
| 87 | regulator should be disabled at LPSR state. |

| 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. |
