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- interrupts:				interrupt mapping for GPIO IRQ, it should be
8					configured with IRQ_TYPE_LEVEL_LOW flag.
9- richtek,output-charge-current:	integer, output current from the charger to the
10					battery, in uA.
11- richtek,end-of-charge-percentage:	integer, percent of the output charge current.
12					When the current in constant-voltage phase drops
13					below output_charge_current x end-of-charge-percentage,
14					charge is terminated.
15- richtek,battery-regulation-voltage:	integer, maximum battery voltage in uV.
16- richtek,boost-output-voltage:		integer, maximum voltage provided to consumer
17					devices, when the charger is in boost mode, in uV.
18
19Optional properties:
20- richtek,min-input-voltage-regulation: integer, input voltage level in uV, used to
21					decrease voltage level when the over current
22					of the input power source occurs.
23					This prevents input voltage drop due to insufficient
24					current provided by the power source.
25					Default: 4500000 uV (4.5V)
26- richtek,avg-input-current-regulation: integer, input current value in uA drained by the
27					charger from the power source.
28					Default: 500000 uA (500mA)
