[PATCH v4 0/5] arm64: dts: qcom: sm8[56]50: add PMIC5 Gen3 ADC channels

Posted by Neil Armstrong 2 days, 18 hours ago

Now the bindings and driver was merged for the SPMI PMIC5 Gen3 ADC
found on the PMK8550 which allow reading ADC data on the PMK8550
and other PMICs on the system.

Add the SPMI ADC channels on the PMK8550 SPMI5 ADC3 for the
other PMICS on the system.

Depends on:

which the bindings tell me is 15. +Dmitry did you grab that value
