Hi Tejun, I have a question, the hip04 and hix5hd2 soc use the old version of IP, but they also have a new version of IP which support FBS and NCQ, and now the new one is used by a new soc. How can I distinguish them, use "hisilicon,hisi-ahci-vX" or just add "generic-ahci" string for the IP which is conformant with spec and has no special customization and issue? Any advices, thanks.
