Qualcomm SPMI PMICs multi-function device bindings
|
||||
|
||||
The Qualcomm SPMI series presently includes PM8941, PM8841 and PMA8084
|
||||
PMICs. These PMICs use a QPNP scheme through SPMI interface.
|
||||
QPNP is effectively a partitioning scheme for dividing the SPMI extended
|
||||
register space up into logical pieces, and set of fixed register
|
||||
locations/definitions within these regions, with some of these regions
|
||||
specifically used for interrupt handling.
|
||||
|
||||
The QPNP PMICs are used with the Qualcomm Snapdragon series SoCs, and are
|
||||
interfaced to the chip via the SPMI (System Power Management Interface) bus.
|
||||
Support for multiple independent functions are implemented by splitting the
|
||||
16-bit SPMI slave address space into 256 smaller fixed-size regions, 256 bytes
|
||||
each. A function can consume one or more of these fixed-size register regions.
|
||||
|
||||
Required properties:
|
||||
- compatible: Should contain one of:
|
||||
"qcom,pm660",
|
||||
"qcom,pm660l",
|
||||
"qcom,pm7325",
|
||||
"qcom,pm8004",
|
||||
"qcom,pm8005",
|
||||
"qcom,pm8019",
|
||||
"qcom,pm8028",
|
||||
"qcom,pm8110",
|
||||
"qcom,pm8150",
|
||||
"qcom,pm8150b",
|
||||
"qcom,pm8150c",
|
||||
"qcom,pm8150l",
|
||||
"qcom,pm8226",
|
||||
"qcom,pm8350c",
|
||||
"qcom,pm8841",
|
||||
"qcom,pm8901",
|
||||
"qcom,pm8909",
|
||||
"qcom,pm8916",
|
||||
"qcom,pm8941",
|
||||
"qcom,pm8950",
|
||||
"qcom,pm8953",
|
||||
"qcom,pm8994",
|
||||
"qcom,pm8998",
|
||||
"qcom,pma8084",
|
||||
"qcom,pmd9635",
|
||||
"qcom,pmi8950",
|
||||
"qcom,pmi8962",
|
||||
"qcom,pmi8994",
|
||||
"qcom,pmi8998",
|
||||
"qcom,pmk8002",
|
||||
"qcom,pmk8350",
|
||||
"qcom,pmr735a",
|
||||
"qcom,smb2351",
|
||||
or generalized "qcom,spmi-pmic".
|
||||
- reg: Specifies the SPMI USID slave address for this device.
|
||||
For more information see:
|
||||
Documentation/devicetree/bindings/spmi/spmi.yaml
|
||||
|
||||
Required properties for peripheral child nodes:
|
||||
- compatible: Should contain "qcom,xxx", where "xxx" is a peripheral name.
|
||||
|
||||
Optional properties for peripheral child nodes:
|
||||
- interrupts: Interrupts are specified as a 4-tuple. For more information
|
||||
see:
|
||||
Documentation/devicetree/bindings/spmi/qcom,spmi-pmic-arb.yaml
|
||||
- interrupt-names: Corresponding interrupt name to the interrupts property
|
||||
|
||||
Each child node of SPMI slave id represents a function of the PMIC. In the
|
||||
example below the rtc device node represents a peripheral of pm8941
|
||||
SID = 0. The regulator device node represents a peripheral of pm8941 SID = 1.
|
||||
|
||||
Example:
|
||||
|
||||
spmi {
|
||||
compatible = "qcom,spmi-pmic-arb";
|
||||
|
||||
pm8941@0 {
|
||||
compatible = "qcom,pm8941", "qcom,spmi-pmic";
|
||||
reg = <0x0 SPMI_USID>;
|
||||
|
||||
rtc {
|
||||
compatible = "qcom,rtc";
|
||||
interrupts = <0x0 0x61 0x1 IRQ_TYPE_EDGE_RISING>;
|
||||
interrupt-names = "alarm";
|
||||
};
|
||||
};
|
||||
|
||||
pm8941@1 {
|
||||
compatible = "qcom,pm8941", "qcom,spmi-pmic";
|
||||
reg = <0x1 SPMI_USID>;
|
||||
|
||||
regulator {
|
||||
compatible = "qcom,regulator";
|
||||
regulator-name = "8941_boost";
|
||||
};
|
||||
};
|
||||
};
