Hi Konrad, Storage team discovered that gpio 136 was inaccessible due to the pinctrl driver issue. So new version patch series will drop gpio 136 from this gpio-reserved-ranges node. New version patch series: https://lore.kernel.org/linux-arm-msm/20231129103325.24854-1-quic_tengfan@quicinc.com/ > > -- Thx and BRs, Tengfei Fan
