The regulator node houses sub-nodes for each regulator within the device. Each

sub-node is identified using the node's name, with valid values listed for each

of the PMICs below.

pm8841:

	s1, s2, s3, s4, s5, s6, s7, s8

pm8916:

	s1, s2, s3, s4, l1, l2, l3, l4, l5, l6, l7, l8, l9, l10, l11, l12, l13,

	l14, l15, l16, l17, l18

pm8941:

	s1, s2, s3, l1, l2, l3, l4, l5, l6, l7, l8, l9, l10, l11, l12, l13, l14,

	l15, l16, l17, l18, l19, l20, l21, l22, l23, l24, lvs1, lvs2, lvs3,

	mvs1, mvs2

The content of each sub-node is defined by the standard binding for regulators -

see regulator.txt - with additional custom properties described below:

- regulator-initial-mode:

	Usage: optional

	Value type: <u32>

	Descrption: 1 = Set initial mode to high power mode (HPM), also referred

		    to as NPM.  HPM consumes more ground current than LPM, but

		    it can source significantly higher load current. HPM is not

		    available on boost type regulators. For voltage switch type

		    regulators, HPM implies that over current protection and

		    soft start are active all the time. 0 = Set initial mode to

		    low power mode (LPM).

Example:

	regulators {

		compatible = "qcom,pm8941-regulators";

		vdd_l1_l3-supply = <&s1>;

		s1: s1 {

			regulator-min-microvolt = <1300000>;

			regulator-max-microvolt = <1400000>;

		};

		...

		l1: l1 {

			regulator-min-microvolt = <1225000>;

			regulator-max-microvolt = <1300000>;

		};

		....

	};

- regulator-microvolt-offset: Offset applied to voltages to compensate for voltage drops

- regulator-min-microamp: smallest current consumers may set

- regulator-max-microamp: largest current consumers may set

- regulator-input-current-limit-microamp: maximum input current regulator allows

- regulator-always-on: boolean, regulator should never be disabled

- regulator-boot-on: bootloader/firmware enabled regulator

- regulator-allow-bypass: allow the regulator to go into bypass mode

- <name>-supply: phandle to the parent supply/regulator node

- regulator-ramp-delay: ramp delay for regulator(in uV/uS)

  For hardware which supports disabling ramp rate, it should be explicitly

  intialised to zero (regulator-ramp-delay = <0>) for disabling ramp delay.

  initialised to zero (regulator-ramp-delay = <0>) for disabling ramp delay.

- regulator-enable-ramp-delay: The time taken, in microseconds, for the supply

  rail to reach the target voltage, plus/minus whatever tolerance the board

  design requires. This property describes the total system ramp time

  required due to the combination of internal ramping of the regulator itself,

  and board design issues such as trace capacitance and load on the supply.

- regulator-soft-start: Enable soft start so that voltage ramps slowly

- regulator-state-mem sub-root node for Suspend-to-RAM mode

  : suspend to memory, the device goes to sleep, but all data stored in memory,

  only some external interrupt can wake the device.

- regulator-initial-mode: initial operating mode. The set of possible operating

  modes depends on the capabilities of every hardware so each device binding

  documentation explains which values the regulator supports.

- regulator-system-load: Load in uA present on regulator that is not captured by

  any consumer request.

- regulator-pull-down: Enable pull down resistor when the regulator is disabled.

Deprecated properties:

- regulator-compatible: If a regulator chip contains multiple

	return 0;
