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. > I talk about a case when driver tree, e.g. different clock maintainer, > takes the binding.
