dt-bindings: iio: qcom: adc7-pm8350: Allow specifying SID for channels 2022-11-07T03:11:11+00:00 Manivannan Sadhasivam manivannan.sadhasivam@linaro.org 2022-11-03T09:57:59+00:00 22f1d06f4f283e36622036726093032a07d67c0d As per the new ADC7 architecture used by the Qualcomm PMICs, each PMIC has the static Slave ID (SID) assigned by default. The primary PMIC PMK8350 is responsible for collecting the temperature/voltage data from the slave PMICs and exposing them via it's registers. For getting the measurements from the slave PMICs, PMK8350 uses the channel ID encoded with the SID of the relevant PMIC. So far, the dt-binding for the slave PMIC PM8350 assumed that there will be only one PM8350 in a system. So it harcoded SID 1 with channel IDs. But this got changed in platforms such as Lenovo X13s where there are a couple of PM8350 PMICs available. So to address multiple PM8350s, change the binding to accept the SID specified by the user and use it for encoding the channel ID. It should be noted that, even though the SID is static it is not globally unique. Only the primary PMIC has the unique SID id 0.
