For example:
- dt-bindings & header with the clock defines in the base/immutable branch
  on top of -rc1
- driver patches on top of the immutable branch, in a PR to Stephen
- dts patches on top of the immutable branch, PR to Arnd

So, clock tree doesn't get the dts, soc tree doesn't get the driver.
Hopefully that clarifies what I meant.

If the other tree just "takes the binding", without some coordination,
then you're SOOL and have to wait a release.

Probably worth Arnd chiming in & just telling us what he is okay with
taking.

Cheers,
