- Qualcomm Technologies, Inc. SMB1390 Charger Specific Bindings
- SMB1390 charge pump is paired with QTI family of standalone chargers to
- enable a high current, high efficiency Li+ battery charging system.
- =======================
- Required Node Structure
- =======================
- SMB1390 Charger must be described in two levels of device nodes.
- ==================================
- First Level Node - SMB1390 Charger
- ==================================
- Charger specific properties:
- - compatible
- Usage: required
- Value type: <string>
- Definition: "qcom,smb1390-charger".
- - qcom,pmic-revid
- Usage: required
- Value type: phandle
- Definition: Should specify the phandle of SMB's revid module. This is used
- to identify the SMB subtype.
- - qcom,channel-num
- Usage: required
- Value type: <u32>
- Definition: Specifies the ADC channel number for reading die temperature.
- ================================================
- Second Level Nodes - SMB1390 Charger Peripherals
- ================================================
- Peripheral specific properties:
- - interrupts
- Usage: required
- Value type: <prop-encoded-array>
- Definition: Peripheral interrupt specifier.
- - interrupt-names
- Usage: required
- Value type: <stringlist>
- Definition: Interrupt names. This list must match up 1-to-1 with the
- interrupts specified in the 'interrupts' property.
- =======
- Example
- =======
- smb1390_charger: qcom,charge_pump {
- compatible = "qcom,smb1390-charger";
- qcom,pmic-revid = <&smb1390_revid>;
- qcom,channel-num = <15>
- interrupt-parent = <&smb1390>;
- qcom,smb-vadc = <&pm8998_vadc>;
- status = "disabled";
- qcom,core {
- interrupts = <0x10 0x0 IRQ_TYPE_EDGE_RISING>,
- <0x10 0x1 IRQ_TYPE_EDGE_RISING>,
- <0x10 0x2 IRQ_TYPE_EDGE_RISING>,
- <0x10 0x3 IRQ_TYPE_EDGE_RISING>,
- <0x10 0x4 IRQ_TYPE_EDGE_RISING>;
- interrupt-names = "switcher-off-window",
- "switcher-off-fault",
- "vph-ov-soft",
- "ilim",
- "temp-alarm";
- };
- };
