Sorry，I’ve verified full functionality with the DTSI on the 7/15 linux-next version, and also checked patch conflicts and checkpatch issues against the 7/22 version.

Based on your comments, I noticed that the DTSI rename from qcs615.dtsi to sm6150.dtsi was already merged on 7/16:
https://lore.kernel.org/all/20250604-qcs615-sm6150-v1-0-2f01fd46c365@oss.qualcomm.com/

I’ll update all related descriptions for qcs615 and sm6150 in the next patch version, and reverify full functionality with the latest linux-next image.

Thanks again for pointing this out.
