- inl67-supply: The input supply for REG_LDO3 and REG_LDO4
Any standard regulator properties can be used to configure the single regulator.
regulator-initial-mode, regulator-allowed-modes and regulator-mode could be
specified using mode values from dt-bindings/regulator/active-semi,8945a-regulator.h
file.
The valid names for regulators are:
REG_DCDC1, REG_DCDC2, REG_DCDC3, REG_LDO1, REG_LDO2, REG_LDO3, REG_LDO4.
Example:
#include <dt-bindings/regulator/active-semi,8945a-regulator.h>
pmic@5b {
compatible = "active-semi,act8945a";
reg = <0x5b>;
