Why not enum with existing part? You are right. I will group the stanalone compatibles into a single enum and sort them alphabetically in v2. > Why not even compatible with existing device? Nord uses the QMP v7 SerDes register layout, whereas sa8775p uses the v5 layout. The offsets differ, so Nord cannot use qcom,sa8775p-dwmac-sgmii-phy as a fallback compatible. > > So many questions, yet commit msg copies subject. > Sorry about that. I mentioned the QMP v7 details in the cover letter but forgot to include them in the commit message. I will expand the commit message in v2 to describe the hardware differences and explain why there is no fallback compatible. Thank you for the review.
