| 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. |
| |
| Example: |
| qcom,spmi@fc4c0000 { |
| #address-cells = <1>; |
| #size-cells = <0>; |
| interrupt-controller; |
| #interrupt-cells = <3>; |
| |
| qcom,pm8941@1 { |
| spmi-slave-container; |
| reg = <0x1>; |
| #address-cells = <1>; |
| #size-cells = <1>; |
| |
| qcom,coincell@2800 { |
| compatible = "qcom,qpnp-coincell"; |
| reg = <0x2800 0x100>; |
| qcom,rset-ohms = <800>; |
| qcom,vset-millivolts = <3100>; |
| qcom,charge-enable = <1>; |
| }; |
| }; |
| }; |
