This module is part of the ROHM BD72720 MFD device. For more details
|
|
see Documentation/devicetree/bindings/mfd/rohm,bd72720-pmic.yaml.
|
|
|
|
The regulator controller is represented as a sub-node of the PMIC node
|
|
on the device tree.
|
|
|
|
Regulator nodes should be named to BUCK_<number> and LDO_<number>.
|
|
The valid names for BD72720 regulator nodes are
|
|
buck1, buck2, buck3, buck4, buck5, buck6, buck7, buck8, buck9, buck10
|
|
ldo1, ldo2, ldo3, ldo4, ldo5, ldo6, ldo7, ldo8, ldo9, ldo10, ldo11

Set this on boards where BUCK10 is used to supply LDOs 1-4. The bucki

voltage will be changed by the PMIC to follow the LDO output voltages
|

with the offset voltage given here. This will improve the LDO efficiency.
