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)
