Firstly, no one is using Ethernet on this platform yet. Secondly, the previous fallback to sm8150 is incorrect and causes packet loss. Instead, it should fall back to qcs404. > >> >> Fixes: 32535b9410b8 ("dt-bindings: net: qcom,ethqos: add description for qcs615") >> Signed-off-by: Yijie Yang <quic_yijiyang@quicinc.com> >> --- >> Documentation/devicetree/bindings/net/qcom,ethqos.yaml | 5 +---- >> 1 file changed, 1 insertion(+), 4 deletions(-) > Best regards, > Krzysztof

One of the purposes of the commit message is to answer questions reviews might have. You were even asked this question, so that should of been a clue to include the answer in the commit message.

The core version of EMAC on qcs615 has minor differences compared to that on sm8150. During the bring-up routine, the loopback bit needs to be set, and the Power-On Reset (POR) status of the registers isn't entirely consistent with sm8150 either. Therefore, it should be treated as a separate entity rather than a fallback option.
