1Binding for Richtek rt9455 battery charger
2
3Required properties:
4- compatible:				it should contain one of the following:
5					"richtek,rt9455".
6- reg:					integer, i2c address of the device.
7- interrupt-parent:			the phandle for the interrupt controller that
8					services interrupts for this device.
9- interrupts:				interrupt mapping for GPIO IRQ, it should be
10					configured with IRQ_TYPE_LEVEL_LOW flag.
11- richtek,output-charge-current:	integer, output current from the charger to the
12					battery, in uA.
13- richtek,end-of-charge-percentage:	integer, percent of the output charge current.
14					When the current in constant-voltage phase drops
15					below output_charge_current x end-of-charge-percentage,
16					charge is terminated.
17- richtek,battery-regulation-voltage:	integer, maximum battery voltage in uV.
18- richtek,boost-output-voltage:		integer, maximum voltage provided to consumer
19					devices, when the charger is in boost mode, in uV.
20
21Optional properties:
22- richtek,min-input-voltage-regulation: integer, input voltage level in uV, used to
23					decrease voltage level when the over current
24					of the input power source occurs.
25					This prevents input voltage drop due to insufficient
26					current provided by the power source.
27					Default: 4500000 uV (4.5V)
28- richtek,avg-input-current-regulation: integer, input current value in uA drained by the
29					charger from the power source.
30					Default: 500000 uA (500mA)
