If that's a valid change, then it looks like a separate fix. I think I can avoid this for now, although it would be needed if this channel number was the virtual channel number made by combining PMIC SID and actual channel number....maybe we can do it in a separate fix. > >> reg = <PM8350_ADC5_GEN2_AMUX_THM4_100K_PU(1)>; >> qcom,ratiometric; >> qcom,hw-settle-time = <200>; >> @@ -307,3 +323,80 @@ examples: >> }; >> }; >> }; >> + >> +#ifndef PM8550_SID >> +#define PM8550_SID 1 >> +#endif >> + >> +/* ADC channels for PM8550_ADC for PMIC5 Gen3 */ >> +#define PM8550_ADC5_GEN3_OFFSET_REF (PM8550_SID << 8 | 0x00) > can we do the naming for the 0x00 as per Dmitry's set?

In this case, minItems: 1 will remain true for all other ADC devices documented here, but it will not be true for ADC5 Gen3, as this one can have multiple base addresses if more than one SDAM is used for ADC.

The property description is right, this property is used to indicate that one of the configurable channels on the ADC SDAMs will be used for ADC_TM functionality, for periodically monitoring this particular ADC channel . This is the exact same functionality as in the existing QCOM ADC_TM device, documented at devicetree/bindings/thermal/qcom-spmi-adc-tm5.yaml. I'll mention this too in the description. It can be considered a property of the hardware as the monitoring is done by a sequence under PBS (Programmable Boot Sequence, can be considered firmware), which periodically gets the channel reading and checks it against upper/lower thresholds set by clients of this driver, for threshold violations. > ... > >>>> then: >>>> patternProperties: >>>> @@ -299,7 +315,7 @@ examples: >>>> label = "xo_therm"; >>>> }; >>>> >>>> diff --git a/include/dt-bindings/iio/qcom,spmi-adc5-gen3-pm8550.h b/include/dt-bindings/iio/qcom,spmi-adc5-gen3-pm8550.h >>>> new file mode 100644 >>>> index 000000000000..74e6e2f6f9ed >>>> --- /dev/null >>>> +++ b/include/dt-bindings/iio/qcom,spmi-adc5-gen3-pm8550.h >>>> @@ -0,0 +1,48 @@ >>>> +/* SPDX-License-Identifier: GPL-2.0-only */ >>> Dual license. >> I think we do have an internal rule by which we do have to add these two >> licenses....I'll check again and update them if required. > Just to be clear: your internal rules are your internal affair.

For the PMIC5-Gen3 type PMICs, ADC peripheral is present in HW for the following PMICs: PMK8550, PM8550, PM8550B and PM8550VX PMICs. It is similar to PMIC5-Gen2, with SW communication to ADCs on all PMICs going through PBS firmware through a single register interface. This interface is implemented on an SDAM peripheral on the master PMIC PMK8550 rather than a dedicated ADC peripheral.
