From bbd7ffdbef6888459f301c5889f3b14ada38b913 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Wed, 8 Apr 2020 23:44:13 -0700 Subject: clk: Allow the common clk framework to be selectable Enable build testing and configuration control of the common clk framework so that more code coverage and testing can be done on the common clk framework across various architectures. This also nicely removes the requirement that architectures must select the framework when they don't use it in architecture code. There's one snag with doing this, and that's making sure that randconfig builds don't select this option when some architecture or platform implements 'struct clk' outside of the common clk framework. Introduce a new config option 'HAVE_LEGACY_CLK' to indicate those platforms that haven't migrated to the common clk framework and therefore shouldn't be allowed to select this new config option. Also add a note that we hope one day to remove this config entirely. Based on a patch by Mark Brown .
