[Sound-open-firmware] A branch can be used as to-be-upstreamed?

Hi,

as we got a bug report about the new Dell laptop with SoundWire audio, I tried to build a kernel with the downstream SOF patches, then I noticed that it's not so trivial to get the patches from SOF git tree that are applicable on top of upstream (either sound or Linus) tree.

Do we have a branch that may contain clean commits on top of the recent upstream? That is, a branch that is regularly rebased, so that each commit can be retrieved as a patch. Such a branch will make upstream submission easier, and it makes easier for distros to take the downstream patches, too.

thanks,

Takashi
