A function can consume one or more of these fixed-size register regions. + + The Qualcomm SPMI series includes the PM8941, PM8841, PMA8084, PM8998 and other + 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. + +maintainers: + - Stephen Boyd <sboyd@kernel.org> + +properties: + compatible: + items: + - enum: + - qcom,pm660 + - qcom,pm660l + - qcom,pm6150 + - qcom,pm6150l + - qcom,pm6350 + - qcom,pm7325 + - qcom,pm8004 + - qcom,pm8005 + - qcom,pm8009 + - qcom,pm8019 + - qcom,pm8110 + - qcom,pm8150 + - qcom,pm8150b + - qcom,pm8150l + - qcom,pm8226 + - qcom,pm8350 + - qcom,pm8350b + - qcom,pm8350c + - qcom,pm8841 + - qcom,pm8909 + - qcom,pm8916 + - qcom,pm8941 + - qcom,pm8950 + - qcom,pm8994 + - qcom,pm8998 + - qcom,pma8084 + - qcom,pmd9635 + - qcom,pmi8950 + - qcom,pmi8962 + - qcom,pmi8994 + - qcom,pmi8998 + - qcom,pmk8350 + - qcom,pmm8155au + - qcom,pmr735a + - qcom,pmr735b + - qcom,pms405 + - qcom,smb2351 + - const: qcom,spmi-pmic + + reg: true + + "#address-cells": + const: 1 + + "#size-cells": + const: 0 + + +patternProperties: + $nodename: + pattern: '^pmic@.*$' + + '(labibb|([a-z][a-z0-9]+-)?regulators)': + type: object + + required: + - compatible + + '@[0-9a-f]+$': + type: object + description: > + Each child node of the PMIC represents a function of it. + + properties: + interrupts: + description: > + Interrupts are specified as a 4-tuple.
