No, that's the wrong order. You apply reviewed patches to the git tree,
they then appear in linux-next, after some time soaking there, you send
a PR (or in your case patches) to soc@...nel.org, usually around rc6 or
rc7. Fixes get applied to a different branch and can be sent at any
time. I expect both branches to appear in linux-next.

Bear in mind that patches for this SoC might be sent by other people,
for example me if I find some issues, and you'll need to forward those
on to soc@...nel.org on top of whatever work you're doing to bring up
the SoC.
