If this is your main concern you should be made aware that there are people out there planning to supplant the existing DT probe paths that are now being added to each and every ARM-related driver with an ACPI probe path as ARM servers come into the picture. > pinctrl is really noticable because it's > new but it's not the only thing.

We did manage to drag the power/voltage domain per se out of the AMBA bus, and recommend that people (like us) do that business using the power domains. I think most people (including OMAP) have bought into the concept of using the runtime PM framework and power domains to control the power domain switches. It's this wider concept of using the loose concept "PM resource domains" to control also clocks and pins that is at stake, and so far the runtime PM core people (Rafael and Magnus) has not said much so I think we need some kind of indication from them as to what is to happen, long-term, with drivers handling their own clocks and pins. Should it be centralized or not? If it's to be centralized it needs to become a large piece of infrastructure refactoring and needs the attention of Linaro and the like to happen. I've CC:ed a few people into this thread so we get some traction, we need more subsystem maintainers in here.
