-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:			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 (%)
-
-Optional properties for Continuous mode:
-- pwm-dutycycle-unit:	Integer value encoding the duty cycle unit. If not
-			defined, <100> is assumed, meaning that
-			pwm-dutycycle-range contains values expressed in
-			percent.
-
-- pwm-dutycycle-range:	Should contain 2 entries. The first entry is encoding
-			the dutycycle for regulator-min-microvolt and the
-			second one the dutycycle for regulator-max-microvolt.
-			Duty cycle values are expressed in pwm-dutycycle-unit.
-			If not defined, <0 100> is assumed.
-
-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.
-
-Optional properties:
---------------------
-- enable-gpios:		GPIO to use to enable/disable the regulator
-
-Any property defined as part of the core regulator binding can also be used.
-(See: ../regulator/regulator.txt)
-
-Continuous Voltage With Enable GPIO Example:
-	pwm_regulator {
-		compatible = "pwm-regulator";
-		pwms = <&pwm1 0 8448 0>;
-		enable-gpios = <&gpio0 23 GPIO_ACTIVE_HIGH>;
-		regulator-min-microvolt = <1016000>;
-		regulator-max-microvolt = <1114000>;
-		regulator-name = "vdd_logic";
-		/* unit == per-mille */
-		pwm-dutycycle-unit = <1000>;
-		/*
-		 * Inverted PWM logic, and the duty cycle range is limited
-		 * to 30%-70%.
-		 */
-		pwm-dutycycle-range = <700 300>; /* */
-	};
-
-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>,
-				<1095000 10>,
-				<1076000 20>,
-				<1056000 30>,
-				<1036000 40>,
-				<1016000 50>;

-- regulator-initial-mode:
-	Usage: optional
-	Value type: <u32>
-	Description: 2 = Set initial mode to auto mode (automatically select
-		    between HPM and LPM); not available on boost type
-		    regulators.
-
-		    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).
-
-- qcom,ocp-max-retries:
-	Usage: optional
-	Value type: <u32>
-	Description: Maximum number of times to try toggling a voltage switch
-		     off and back on as a result of consecutive over current
-		     events.
-
-- qcom,ocp-retry-delay:
-	Usage: optional
-	Value type: <u32>
-	Description: Time to delay in milliseconds between each voltage switch
-		     toggle after an over current event takes place.
-
