| description: | |
| List of regulators provided by this controller. BD71837 regulators node |
| should be sub node of the BD71837 MFD node. See BD71837 MFD bindings at |
| Documentation/devicetree/bindings/mfd/rohm,bd71837-pmic.yaml |
| Regulator nodes should be named to BUCK_<number> and LDO_<number>. The |
| definition for each of these nodes is defined using the standard |
| binding for regulators at |
| Documentation/devicetree/bindings/regulator/regulator.txt. |
| Note that if BD71837 starts at RUN state you probably want to use |
| regulator-boot-on at least for BUCK6 and BUCK7 so that those are not |
| disabled by driver at startup. LDO5 and LDO6 are supplied by those and |
| if they are disabled at startup the voltage monitoring for LDO5/LDO6 will |
| cause PMIC to reset. |
| |
| #The valid names for BD71837 regulator nodes are: |
| #BUCK1, BUCK2, BUCK3, BUCK4, BUCK5, BUCK6, BUCK7, BUCK8 |
| #LDO1, LDO2, LDO3, LDO4, LDO5, LDO6, LDO7 |

| # BD71837 power outputs can either be controlled by the PMIC internal |
| # hardware state machine or by software. If you need regulators to be |
| # turned ON/OFF for example based on PMIC_STBY_REQ line (which toggles |
| # PMIC HW state machine) - then you should set this property. |
| # Tradeoff is that then SW can't control the ON/OFF state for this |
| # regulator (other than invoking a PMIC state change). |
