That's where CC_OUT pin is. I don't think we represented this correctly, but rather copy-pasted downstream solution... Best regards, Krzysztof

We do not interact directly with PM8350B or PM8550B but with pmic_glink who does the work work for use, and this is platform specific. Neil > > Best regards, > Krzysztof >

Yep, pmic_glink is totally a firmware construct and not all platforms with pm8350b or so implement it. Konrad > > Neil > >> >> Best regards, >> Krzysztof >> >

The drivers interact like this, but there is no pmic glink on schematics but PM8350B and PM8550 and DT represents here the hardware, thus the schematics, not your chosen way of interface. This looks like a copy of downstream choice which is in most cases just wrong choice. Best regards, Krzysztof
