Subject: Re: [PATCH v2 07/10] clk: Allow the common clk framework to be selectable

Quoting Stephen Boyd (2020-04-08 23:44:13)
> 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.
