+Hisilicon Hi655x Voltage regulators
+
+Note:
+The hi655x regulator control is managed by hi655x Power IC.
+So the node of this regulator must be child node of hi655x
+pmic node.
+
+The driver uses the regulator core framework, so please also
+take the bindings of regulator.txt for reference.
+
+Required properties:
+- compatible: Must be "hisilicon,hi655x-regulator-pmic";
+- regulator-ctrl-regs: Registers offset of control register,
+ In turn with enable disable and status register offset.
+- regulator-ctrl-mask: The control mask bit of the register.
+- regulator-vset-regs: Voltage set register offset.
+- regulator-vset-mask: voltage set control mask.
+- regulator-n-vol: The num of support voltages.
+- regulator-vset-table: The table of support voltages.
+
+Example:
+ pmic: pmic@f8000000 {
+ compatible = "hisilicon,hi655x-pmic";
+ ...
+ ldo7: regulator@a26 {
+ compatible = "hisilicon,hi655x-regulator-pmic";
+ regulator-name = "ldo7";
+ regulator-min-microvolt = <1800000>;
+ regulator-max-microvolt = <3300000>;
+ regulator-valid-modes-mask = <0x0a>;
+ regulator-enable-ramp-delay = <120>;
+ regulator-ctrl-regs = <0x029 0x02a 0x02b>;
+ regulator-ctrl-mask = <0x6>;
+ regulator-vset-regs = <0x078>;
+ regulator-vset-mask = <0x7>;
+ regulator-n-vol = <8>;
+ regulator-vset-table = <1800000>,<1850000>,
+ <2850000>,<2900000>,
+ <3000000>,<3100000>,
+ <3200000>,<3300000>;
+ };
+ ...
