Qualcomm QPNP Coincell - coincell battery charger devices
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: Must be "qcom,qpnp-coincell".
|
||
|
|
- reg: Specifies the SPMI address and size for this coincell device.
|
||
|
|
|
||
|
|
Required structure:
|
||
|
|
- A qcom,qpnp-coincell node must be a child of an SPMI node that has specified
|
||
|
|
the spmi-slave-container property.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- qcom,rset-ohms: Specifies the resistance of the current limiting
|
||
|
|
resistor in ohms. Four values are supported:
|
||
|
|
800, 1200, 1700, and 2100.
|
||
|
|
- qcom,vset-millivolts: Specifies the coincell charging voltage in millivolts.
|
||
|
|
Four values are supported: 2500, 3000, 3100, and 3200.
|
||
|
|
- qcom,charge-enable: Specifies if coincell charging should be enabled or not.
|
||
|
|
0 = disable charging, 1 = enabled charging
|
||
|
|
|
||
|
|
If any of the optional properties are not specified, then the hardware default
|
||
|
|
values for the unspecified properties will be used instead.
|
||
|
|
|
||
|
|

|
||
|
|
qcom,spmi@fc4c0000 {

reg = <0x2800 0x100>;
|
||
|
|
qcom,rset-ohms = <800>;
|
||
|
