-Binding for Richtek rt9455 battery charger
-
-Required properties:
-- compatible:				it should contain one of the following:
-					"richtek,rt9455".
-- reg:					integer, i2c address of the device.
-- interrupts:				interrupt mapping for GPIO IRQ, it should be
-					configured with IRQ_TYPE_LEVEL_LOW flag.
-- richtek,output-charge-current:	integer, output current from the charger to the
-					battery, in uA.
-- richtek,end-of-charge-percentage:	integer, percent of the output charge current.
-					When the current in constant-voltage phase drops
-					below output_charge_current x end-of-charge-percentage,
-					charge is terminated.
-- richtek,battery-regulation-voltage:	integer, maximum battery voltage in uV.
-- richtek,boost-output-voltage:		integer, maximum voltage provided to consumer
-					devices, when the charger is in boost mode, in uV.
-
-Optional properties:
-- richtek,min-input-voltage-regulation: integer, input voltage level in uV, used to
-					decrease voltage level when the over current
-					of the input power source occurs.
-					This prevents input voltage drop due to insufficient
-					current provided by the power source.
-					Default: 4500000 uV (4.5V)
-- richtek,avg-input-current-regulation: integer, input current value in uA drained by the
-					charger from the power source.
-					Default: 500000 uA (500mA)
