[PATCH v3 1/6] regulator: dt-binding: regulator-max77620: convert to DT schema

[Svyatoslav Ryhel <clamor95@gmail.com>]

Convert regulator-max77620 devicetree bindings for the MAX77620 PMIC from
TXT to YAML format. This patch does not change any functionality; the
bindings remain the same.

-Regulator DT binding for MAX77620 Power management IC from Maxim Semiconductor.
-
-Device has multiple DCDC(sd[0-3] and LDOs(ldo[0-8]). The input supply
-of these regulators are defined under parent device node.
-Details of regulator properties are defined as child node under
-sub-node "regulators" which is child node of device node.
-
-Please refer file <Documentation/devicetree/bindings/regulator/regulator.txt>
-for common regulator bindings used by client.
-
-Following are properties of parent node related to regulators.
-
-Optional properties:
--------------------
-The input supply of regulators are the optional properties on the
-parent device node. The input supply of these regulators are provided
-through following properties:
-in-sd0-supply:		Input supply for SD0, INA-SD0 or INB-SD0 pins.
-in-sd1-supply:		Input supply for SD1.
-in-sd2-supply:		Input supply for SD2.
-in-sd3-supply:		Input supply for SD3.
-in-ldo0-1-supply:	Input supply for LDO0 and LDO1.
-in-ldo2-supply:		Input supply for LDO2.
-in-ldo3-5-supply:	Input supply for LDO3 and LDO5
-in-ldo4-6-supply:	Input supply for LDO4 and LDO6.
-in-ldo7-8-supply:	Input supply for LDO7 and LDO8.
-
-Optional sub nodes for regulators under "regulators" subnode:
-------------------------------------------------------------
-The subnodes name is the name of regulator and it must be one of:
-	sd[0-3], ldo[0-8]
-
-Each sub-node should contain the constraints and initialization
-information for that regulator. The definition for each of these
-nodes is defined using the standard binding for regulators found at
-<Documentation/devicetree/bindings/regulator/regulator.txt>.
-
-There are also additional properties for SD/LDOs. These additional properties
-are required to configure FPS configuration parameters for SDs and LDOs.
-Please refer <devicetree/bindings/mfd/max77620.txt> for more detail of Flexible
-Power Sequence (FPS).
-Following are additional properties:
-
-- maxim,active-fps-source:		FPS source for the regulators to get
-					enabled/disabled when system is in
-					active state.  Valid values are:
-					- MAX77620_FPS_SRC_0,
-						FPS source is FPS0.
-					- MAX77620_FPS_SRC_1,
-						FPS source is FPS1
-					- MAX77620_FPS_SRC_2 and
-						FPS source is FPS2
-					- MAX77620_FPS_SRC_NONE.
-						Regulator is not controlled
-						by FPS events and it gets
-						enabled/disabled by register
-						access.
-					Absence of this property will leave
-					the FPS configuration register for that
-					regulator to default configuration.
-
-- maxim,active-fps-power-up-slot:	Sequencing event slot number on which
-					the regulator get enabled when
-					master FPS input event set to HIGH.
-					Valid values are 0 to 7.
-					This is applicable if FPS source is
-					selected as FPS0, FPS1 or FPS2.
-			
-- maxim,active-fps-power-down-slot:	Sequencing event slot number on which
-					the regulator get disabled when master
-					FPS input event set to LOW.
-					Valid values are 0 to 7.
-					This is applicable if FPS source is
-					selected as FPS0, FPS1 or FPS2.
-			
-- maxim,suspend-fps-source:		This is same as property
-					"maxim,active-fps-source" but value
-					get configured when system enters in
-					to suspend state.
-
-- maxim,suspend-fps-power-up-slot:	This is same as property
-					"maxim,active-fps-power-up-slot" but
-					this value get configured into FPS
-					configuration register when system
-					enters into suspend.
-					This is applicable if suspend state
-					FPS source is selected as FPS0, FPS1 or
-
-- maxim,suspend-fps-power-down-slot:	This is same as property
-					"maxim,active-fps-power-down-slot" but
-					this value get configured into FPS
-					configuration register when system
-					enters into suspend.
-					This is applicable if suspend state
-					FPS source is selected as FPS0, FPS1 or
-					FPS2.
-- maxim,ramp-rate-setting:		integer, ramp rate(uV/us) setting to be
-					configured to the device.
-					The platform may have different ramp
-					rate than advertised ramp rate if it has
-					design variation from Maxim's
-					recommended. On this case, platform
-					specific ramp rate is used for ramp time
-					calculation and this property is used
-					for device register configurations.
-					The measured ramp rate of platform is
-					provided by the regulator-ramp-delay
-					as described in <devicetree/bindings/
-					regulator/regulator.txt>.
-					Maxim Max77620 supports following ramp
-					delay:
-					  SD: 13.75mV/us, 27.5mV/us, 55mV/us
-					  LDOs: 5mV/us, 100mV/us
-
-Note: If the measured ramp delay is same as advertised ramp delay then it is not
-required to provide the ramp delay with property "maxim,ramp-rate-setting". The
-ramp rate can be provided by the regulator-ramp-delay which will be used for
-ramp time calculation for voltage change as well as for device configuration.
