That made more sense because the electrical differences are what made the PHY init sequence changes necessary. Here, Krzysztof is trying to express that the pmic-glink interface found on SM8475 is likely no different than the one found on SM8450 (and SM8350 and so on) Then, since it's the same, it can reuse the same driver match data, so patch 2 is unnecessary, since the driver binds said match data on the fallback "qcom,pmic-glink" compatible Konrad
