- 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";
