From 43e60861fe9d39740cf5b355f58fecedf0d8e9ba Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 11 Nov 2010 01:51:26 +0100 Subject: PM / OPP: Hide OPP configuration when SoCs do not provide an implementation Since the OPP API is only useful with an appropraite SoC-specific implementation there is no point in offering the ability to enable the API on general systems. Provide an ARCH_HAS OPP Kconfig symbol which masks out the option unless selected by an implementation.
