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
