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: + $nodename: + oneOf: + - pattern: '^pmic@.*$' + - pattern: '^pm(a|s)?[0-9]*@.*$' + deprecated: true + + compatible: + items: + - enum: + - qcom,pm6150 + - qcom,pm6150l + - qcom,pm6350 + - qcom,pm660 + - qcom,pm660l + - qcom,pm7250b + - qcom,pm7325 + - qcom,pm8004 + - qcom,pm8005 + - qcom,pm8009 + - qcom,pm8019 + - qcom,pm8028 + - qcom,pm8110 + - qcom,pm8150 + - qcom,pm8150b + - qcom,pm8150c + - qcom,pm8150l + - qcom,pm8226 + - qcom,pm8350 + - qcom,pm8350b + - qcom,pm8350c + - qcom,pm8841 + - 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,pmm8155au + - qcom,pmp8074 + - qcom,pmr735a + - qcom,pmr735b + - qcom,pms405 + - qcom,pmx55 + - qcom,pmx65 + - qcom,smb2351 + - const: qcom,spmi-pmic + + reg: + minItems: 1 + maxItems: 2 + + '#address-cells': + const: 1 + + '#size-cells': + const: 0 + + labibb: + type: object + $ref: /schemas/regulator/qcom-labibb-regulator.yaml# + + regulators: + type: object + $ref: /schemas/regulator/qcom,spmi-regulator.yaml# + + pwm: + type: object + $ref: /schemas/leds/leds-qcom-lpg.yaml# + +patternProperties: + "^adc@[0-9a-f]+$": + type: object + $ref: /schemas/iio/adc/qcom,spmi-vadc.yaml# + + "^adc-tm@[0-9a-f]+$": + type: object + # ref depends on compatible, see allOf below + + "^audio-codec@[0-9a-f]+$": + type: object + additionalProperties: true # FIXME qcom,pm8916-wcd-analog-codec binding not converted yet + + "extcon@[0-9a-f]+$": + type: object + $ref: /schemas/extcon/qcom,pm8941-misc.yaml# + + "gpio(s)?@[0-9a-f]+$": + type: object + $ref: /schemas/pinctrl/qcom,pmic-gpio.yaml# + + "pon@[0-9a-f]+$": + type: object + $ref: /schemas/power/reset/qcom,pon.yaml# + + "^rtc@[0-9a-f]+$": + type: object + $ref: /schemas/rtc/qcom-pm8xxx-rtc.yaml# + + "^temp-alarm@[0-9a-f]+$": + type: object + $ref: /schemas/thermal/qcom,spmi-temp-alarm.yaml# + + "^vibrator@[0-9a-f]+$": + type: object + additionalProperties: true # FIXME qcom,pm8916-vib binding not converted yet + + "^mpps@[0-9a-f]+$": + type: object + $ref: /schemas/pinctrl/qcom,pmic-mpp.yaml# + + "(.*)?(wled|leds)@[0-9a-f]+$": + type: object + $ref: /schemas/leds/backlight/qcom-wled.yaml# + unevaluatedProperties: false + +required: + - compatible + - reg + +allOf: + - if: + properties: + compatible: + contains: + enum: + - qcom,pm8998 + then: + patternProperties: + "^adc-tm@[0-9a-f]+$": + $ref: /schemas/thermal/qcom-spmi-adc-tm-hc.yaml# + else: + patternProperties: + "^adc-tm@[0-9a-f]+$": + $ref: /schemas/thermal/qcom-spmi-adc-tm5.yaml# + +additionalProperties: false + +examples: + - | + #include <dt-bindings/spmi/spmi.h> + #include <dt-bindings/interrupt-controller/irq.h> + #include <dt-bindings/interrupt-controller/arm-gic.h> + + spmi@c440000 { + compatible = "qcom,spmi-pmic-arb";
