OK, I'll try to move it up. To be fair though, every change that has any dependency is clearly noted in its below-the-fold notes. > You combined here like 5 > different subsystens... What do you recommend here? I believe the general principles of DT binding development suggest there should be a single binding doc for describing the "Central Power Manager" (and the services it supports). CPM supports functionality covered by many subsystems. While in theory, bindings can be written without corresponding software support (drivers), in practice it usually works out better to develop them together, to prove that the binding describes the hardware/firmware sufficiently. And even if the binding goes separately, I don't think I can 100% split the driver support by subsystem, as they all require the same underlying CPM helpers, and those helpers don't have much meaning without their clients. So some multi-subsystem work is still necessary IMO. So I don't really see how I can address your complaint. But I'm open to your ideas. Brian
