| 13 | List of regulators provided by this controller. BD71847 regulators node | |
| 14 | should be sub node of the BD71847 MFD node. See BD71847 MFD bindings at | |
| 15 | Documentation/devicetree/bindings/mfd/rohm,bd71847-pmic.yaml | |
| 16 | Regulator nodes should be named to BUCK_<number> and LDO_<number>. The | |
| 17 | definition for each of these nodes is defined using the standard | |
| 18 | binding for regulators at | |
| 19 | Documentation/devicetree/bindings/regulator/regulator.txt. | |
| 20 | Note that if BD71847 starts at RUN state you probably want to use | |
| 21 | regulator-boot-on at least for BUCK5. LDO6 is supplied by it and it must | |
| 22 | not be disabled by driver at startup. If BUCK5 is disabled at startup the | |
| 23 | voltage monitoring for LDO5/LDO6 can cause PMIC to reset. | |
| 24 | ||
| 25 | #The valid names for BD71847 regulator nodes are: | |
| 26 | #BUCK1, BUCK2, BUCK3, BUCK4, BUCK5, BUCK6 | |
| 27 | #LDO1, LDO2, LDO3, LDO4, LDO5, LDO6 | |
