As pointed out in [1], the Linux implementation of RSC basically requires (even if not explicitly) that we point it to a power domain which represents the power state of the CPUs. In an effort to fulfill that requirement, make it required in bindings and hook it up on all platforms where I was able to do. This means all RPMh platforms, except - SC7180 - SC7280 - SA8775 As there wasn't an idle-states setup (which may be on purpose for CrOS devices, certainly not for Windows SC7[12]80s) that I could validate. (Doug, Bartosz, could you guys look into your respective platforms of interest here?) This series also adds support for idle states on SM6350, as I was able to add and test that.
