Re: [PATCH v3 2/2] arm64: dts: qcom: sm8550: Add support for Samsung Galaxy Z Fold5

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

Hi, thanks, that's strange, I am already using the right kernel source that has the mentioned patches...
I am going to check why the dtb was successfully compiled, remove all the mentioned issues and generate a v4
