| 13 | List of regulators provided by this controller. BD71837 regulators node | |
| 14 | should be sub node of the BD71837 MFD node. See BD71837 MFD bindings at | |
| 15 | Documentation/devicetree/bindings/mfd/rohm,bd71837-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 BD71837 starts at RUN state you probably want to use | |
| 21 | regulator-boot-on at least for BUCK6 and BUCK7 so that those are not | |
| 22 | disabled by driver at startup. LDO5 and LDO6 are supplied by those and | |
| 23 | if they are disabled at startup the voltage monitoring for LDO5/LDO6 will | |
| 24 | cause PMIC to reset. | |
| 25 | ||
| 26 | #The valid names for BD71837 regulator nodes are: | |
| 27 | #BUCK1, BUCK2, BUCK3, BUCK4, BUCK5, BUCK6, BUCK7, BUCK8 | |
| 28 | #LDO1, LDO2, LDO3, LDO4, LDO5, LDO6, LDO7 | |
