-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)
