[PATCH v2 4/4] dt-bindings: mfd: maxim,max77693: convert to dtschema

[Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com>]

Convert the MFD part of Maxim MAX77693 MUIC to DT schema format.  The
example DTS was copied from existing DTS (exynos4412-midas.dtsi), so
keep the license as GPL-2.0-only.

-Maxim MAX77693 multi-function device
-
-MAX77693 is a Multifunction device with the following submodules:
-- PMIC,
-- CHARGER,
-- LED,
-- MUIC,
-- HAPTIC
-
-It is interfaced to host controller using i2c.
-This document describes the bindings for the mfd device.
-
-Required properties:
-- compatible : Must be "maxim,max77693".
-- reg : Specifies the i2c slave address of PMIC block.
-- interrupts : This i2c device has an IRQ line connected to the main SoC.
-
-Optional properties:
-- regulators : The regulators of max77693 have to be instantiated under subnode
-  named "regulators" using the following format.
-
-	regulators {
-		regulator-compatible = ESAFEOUT1/ESAFEOUT2/CHARGER
-		standard regulator constraints[*].
-	};
-
-	[*] refer Documentation/devicetree/bindings/regulator/regulator.txt
-
-- haptic : The MAX77693 haptic device utilises a PWM controlled motor to provide
-  users with tactile feedback. PWM period and duty-cycle are varied in
-  order to provide the appropriate level of feedback.
-
- Required properties:
-	- compatible : Must be "maxim,max77693-haptic"
-	- haptic-supply : power supply for the haptic motor
-	[*] refer Documentation/devicetree/bindings/regulator/regulator.txt
-	- pwms : phandle to the physical PWM(Pulse Width Modulation) device.
-	 PWM properties should be named "pwms". And number of cell is different
-	 for each pwm device.
-	 To get more information, please refer to documentation.
-	[*] refer Documentation/devicetree/bindings/pwm/pwm.txt
-
-- charger : Node configuring the charger driver.
-  If present, required properties:
-  - compatible : Must be "maxim,max77693-charger".
-
-  Optional properties (if not set, defaults will be used):
-  - maxim,constant-microvolt : Battery constant voltage in uV. The charger
-    will operate in fast charge constant current mode till battery voltage
-    reaches this level. Then the charger will switch to fast charge constant
-    voltage mode. Also vsys (system voltage) will be set to this value when
-    DC power is supplied but charger is not enabled.
-    Valid values: 3650000 - 4400000, step by 25000 (rounded down)
-    Default: 4200000
-
-  - maxim,min-system-microvolt : Minimal system voltage in uV.
-    Valid values: 3000000 - 3700000, step by 100000 (rounded down)
-    Default: 3600000
-
-  - maxim,thermal-regulation-celsius : Temperature in Celsius for entering
-    high temperature charging mode. If die temperature exceeds this value
-    the charging current will be reduced by 105 mA/Celsius.
-    Valid values: 70, 85, 100, 115
-    Default: 100
-
-  - maxim,battery-overcurrent-microamp : Overcurrent protection threshold
-    in uA (current from battery to system).
-    Valid values: 2000000 - 3500000, step by 250000 (rounded down)
-    Default: 3500000
-
-  - maxim,charge-input-threshold-microvolt : Threshold voltage in uV for
-    triggering input voltage regulation loop. If input voltage decreases
-    below this value, the input current will be reduced to reach the
-    threshold voltage.
-    Valid values: 4300000, 4700000, 4800000, 4900000
-    Default: 4300000
-
-- led : the LED submodule device node
-
-There are two LED outputs available - FLED1 and FLED2. Each of them can
-control a separate LED or they can be connected together to double
-the maximum current for a single connected LED. One LED is represented
-by one child node.
-
-Required properties:
-- compatible : Must be "maxim,max77693-led".
-
-Optional properties:
-- maxim,boost-mode :
-	In boost mode the device can produce up to 1.2A of total current
-	on both outputs. The maximum current on each output is reduced
-	to 625mA then. If not enabled explicitly, boost setting defaults to
-	LEDS_BOOST_FIXED in case both current sources are used.
-	Possible values:
-		LEDS_BOOST_OFF (0) - no boost,
-		LEDS_BOOST_ADAPTIVE (1) - adaptive mode,
-		LEDS_BOOST_FIXED (2) - fixed mode.
-- maxim,boost-mvout : Output voltage of the boost module in millivolts.
-	Valid values: 3300 - 5500, step by 25 (rounded down)
-	Default: 3300
-- maxim,mvsys-min : Low input voltage level in millivolts. Flash is not fired
-	if chip estimates that system voltage could drop below this level due
-	to flash power consumption.
-	Valid values: 2400 - 3400, step by 33 (rounded down)
-	Default: 2400
-
-Required properties for the LED child node:
-- led-sources : see Documentation/devicetree/bindings/leds/common.txt;
-		device current output identifiers: 0 - FLED1, 1 - FLED2
-- led-max-microamp : see Documentation/devicetree/bindings/leds/common.txt
-	Valid values for a LED connected to one FLED output:
