In addition to what others have said, I think you should include
fixes tags for this, so something like:

Fixes: ff499a0fbb23 ("arm64: dts: qcom: sa8775p: add the first 1Gb ethernet interface")
Fixes: e952348a7cc7 ("arm64: dts: qcom: sa8775p: add a node for EMAC1")

to indicate this isn't just an improvement, but a proper bug fix.

Thanks,
Andrew
