SoC framework -> modifies on required cases certain OPPs -> OPP layer
-> queries to search/retrieve information ->
-Architectures that provide a SoC framework for OPP should select ARCH_HAS_OPP
-to make the OPP layer available.
-
OPP layer expects each domain to be represented by a unique device pointer. SoC
framework registers a set of initial OPPs per device with the OPP layer. This
list is expected to be an optimally small number typically around 5 per device.
