+* MSM EXT BUCK SUPPORT
+
+EXT BUCK SUPPORT driver is for supporting the external buck controlled by RPM.

+supporting external buck by toggling a gpio to trun-on and turn-off external
+buck.
+
+The required properties for EXT BUCK SUPPORT are:
+
+- compatible: "qcom,ext-buck-support"
+
+The optional properties are:
+- qcom,gpio-num: Indicates the GPIO number which will turn-on and turn-off

+- qcom,settling-time: Indicates the settling time for the external buck to
+		      get turn-on or turn-off. Settling time is calculated
+		      in terms of QTIMER(19.2MHz).
+
+Example:
+	qcom,ext-buck-support {
+		compatible = "qcom,ext-buck-support";
+		qcom,gpio-num = <50>;
+		qcom,settling-time = <2580>;

+The FAN53555 is a step-down switching voltage regulator that delivers a

+Required Properties:
+- compatible:			Must be "fairchild,fan53555-regulator".

+ON Semiconductor NCP6335d regulator
+
+NCP6335d is able to deliver up to 5.0 A, with programmable output voltage from
+0.6 V to 1.87 V in 10mV steps, with synchronous rectification and automatic PWM/
+PFM transitions, enable pins and power good/fail signaling.
+
+The NCP6335d interface is via I2C bus.
+
+Required Properties:
+- compatible:			Must be "onnn,ncp6335d-regulator".
+- reg:				The device 8-bit I2C address.
+- regulator-min-microvolt:	Minimum voltage in microvolts supported by this
+				regulator.
+- regulator-max-microvolt:	Maximum voltage in microvolts supported by this
+				regulator.
+- onnn,min-setpoint:		Minimum setpoint voltage in microvolts supported
+				by this regulator.
+- onnn,step-size:		The step size of the regulator, in uV.
+- onnn,min-slew-ns:		Minimum time in ns needed to change voltage by
+				one step size. This value corresponds to DVS
+				mode bit of 00b in command register.
+- onnn,max-slew-ns:		Maximum time in ns needed to change voltage by
+				one step size. This value corresponds to DVS
+				mode bit of 11b in command register.
+- onnn,vsel:			Working vsel register. Supported value are 0
+				or 1.
+- onnn,slew-ns:			Time in ns needed to change voltage by one step
+				size. Supported value are 333, 666, 1333, 2666.
+
+Optional Properties:
+- onnn,discharge-enable:	Present: discharge enabled.
+				Not Present: discharge disabled.
+- onnn,restore-reg:		Present: Restore vsel register from backup register.
+				Not Present: No restore.
+- onnn,vsel-gpio:		Present: GPIO connects to the VSEL pin and set the
+				VSEL pin according to device tree flag.
+				Not Present: No GPIO is connected to vsel pin.
+- onnn,sleep-enable:		Present: Forced in sleep mode when EN and VSEL
+				pins are low.
+				Not Present: Low quiescent current mode when EN and VSEL
+				pins are low.
+- onnn,tlmm-config:		Array of 2 elements to indicate the mask value and the value
+				to write in the masked bits.
+				This property is used to allow the VSEL GPIO to toggle on certain
+				Qualcomm processors. If it is not specified, then no register write is required.
+				The 2 elements with index[0..1] are:
+				[0] => the mask value;
+				[1] => the value to write into the masked bits.
+- onnn,mode:			A string which specifies the initial mode to use for the regulator.
+				Supported values are "pwm" and "auto". PWM mode is more
+				robust, but draws more current than auto mode. If this propery
+				is not specified, then the regulator will be in the hardware default mode.
