Mediatek MT6311 Regulator Driver

Required properties:

- compatible: "mediatek,mt6311-regulator"

- reg: I2C slave address, usually 0x6b.

- regulators: List of regulators provided by this controller. It is named

  to VDVFS and VBIASN.

  The definition for each of these nodes is defined using the standard binding

  for regulators at Documentation/devicetree/bindings/regulator/regulator.txt.

The valid names for regulators are:

BUCK:

  VDVFS

LDO:

  VBIASN

Example:

	mt6311: pmic@6b {

		compatible = "mediatek,mt6311-regulator";

		reg = <0x6b>;

		regulators {

			mt6311_vcpu_reg: VDVFS {

				regulator-name = "VDVFS";

				regulator-min-microvolt = < 600000>;

				regulator-max-microvolt = <1400000>;

				regulator-ramp-delay = <10000>;

			};

			mt6311_ldo_reg: VBIASN {

				regulator-name = "VBIASN";

				regulator-min-microvolt = <200000>;

				regulator-max-microvolt = <800000>;

			};

		};

	};

pwm regulator bindings

Bindings for the Generic PWM Regulator

======================================

Currently supports 2 modes of operation:

Voltage Table:		When in this mode, a voltage table (See below) of

			predefined voltage <=> duty-cycle values must be

			provided via DT. Limitations are that the regulator can

			only operate at the voltages supplied in the table.

			Intermediary duty-cycle values which would normally

			allow finer grained voltage selection are ignored and

			rendered useless.  Although more control is given to

			the user if the assumptions made in continuous-voltage

			mode do not reign true.

Continuous Voltage:	This mode uses the regulator's maximum and minimum

			supplied voltages specified in the

			regulator-{min,max}-microvolt properties to calculate

			appropriate duty-cycle values.  This allows for a much

			more fine grained solution when compared with

			voltage-table mode above.  This solution does make an

			assumption that a %50 duty-cycle value will cause the

			regulator voltage to run at half way between the

			supplied max_uV and min_uV values.

Required properties:

--------------------

- compatible:		Should be "pwm-regulator"

- pwms: OF device-tree PWM specification (see PWM binding pwm.txt)

- voltage-table: voltage and duty table, include 2 members in each set of

  brackets, first one is voltage(unit: uv), the next is duty(unit: percent)

Any property defined as part of the core regulator binding defined in

regulator.txt can also be used.

- pwms:			PWM specification (See: ../pwm/pwm.txt)

Only required for Voltage Table Mode:

- voltage-table: 	Voltage and Duty-Cycle table consisting of 2 cells

			    First cell is voltage in microvolts (uV)

			    Second cell is duty-cycle in percent (%)

NB: To be clear, if voltage-table is provided, then the device will be used

in Voltage Table Mode.  If no voltage-table is provided, then the device will

be used in Continuous Voltage Mode.

Any property defined as part of the core regulator binding can also be used.

(See: ../regulator/regulator.txt)

Example:

Continuous Voltage Example:

	pwm_regulator {

		compatible = "pwm-regulator;

		pwms = <&pwm1 0 8448 0>;

		regulator-min-microvolt = <1016000>;

		regulator-max-microvolt = <1114000>;

		regulator-name = "vdd_logic";

	};

Voltage Table Example:

	pwm_regulator {

		compatible = "pwm-regulator;

		pwms = <&pwm1 0 8448 0>;

		regulator-min-microvolt = <1016000>;

		regulator-max-microvolt = <1114000>;

		regulator-name = "vdd_logic";

			      /* Voltage Duty-Cycle */

		voltage-table = <1114000 0>,

				<1076000 20>,

				<1056000 30>,

		regulator-max-microvolt = <1114000>;

		regulator-name = "vdd_logic";
