Binding for sc8551 battery charger
|
|
Required properties:
|
- compatible: "sc,sc8551-standalone" for sc8551 Charger Power Supply
|
- monitored-battery: phandle of battery characteristics devicetree node
|
- interrupts: Interrupt mapping for GPIO IRQ. Use in conjunction with
|
"interrupt-parent". If an interrupt is not provided the driver will switch
|
automatically to polling.
|
|
- input-voltage-limit-microvolt: integer, input voltage level in uV, used to
|
decrease voltage level when the over current
|
of the input power source occurs.
|
- input-current-limit-microamp: integer, input current value in uA drained by the
|
charger from the power source.Default: 500000 uA (500mA)
|
|
- sc,sc8551,bat-ovp-disable: enable the battery over voltage protection
|
- sc,sc8551,bat-ocp-disable: enable the battery over current protection
|
- sc,sc8551,bus-ocp-disable: enable the bus over voltage protection
|
- sc,sc8551,bat-ovp-threshold: Configures the battery over voltage protection voltage (in uV).
|
- sc,sc8551,bat-ocp-threshold: Configures the battery over current protection voltage (in uA).
|
- sc,sc8551,bus-ovp-threshold: Configures the bus over voltage protection voltage (in uV).
|
- sc,sc8551,bus-ocp-threshold: Configures the bus over current protection voltage (in uA).
|
- sc,sc8551,ac-ovp-threshold: Configures the AC voltage protection voltage (in uV).
|
- sc,sc8551,sense-resistor-mohm: integer, value of a resistor in series with the battery;
|
|
