@@ -37,6 +37,9 @@ Typical usage of the OPP library is as follows:
 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.
