Hi,
I'm retaking Rabin's patches [0] for splitting the clk API in two: one API for clk consumers and another for providers. The consumer API uses a clk structure that just keeps track of the consumer and has a reference to the actual clk_core struct, which is used internally.
I have kept a patch from Rabin that aims to aid in debugging nested enable/disable calls, though my personal aim is to allow more than one consumer to influence the final, effective frequency rate. For now this is limited to setting floor and ceiling constraints, with the short-term aim of allowing devfreq and thermal drivers to set floor and ceiling frequencies on the memory clock, respectively.
For those functions in the consumer clk API that were called from providers, I have added variants to clk-provider.h that are the same only that accept a clk_core instead. These functions are prefixed with clk_provider_.
Patch 1/6 just adds a bunch of defines with the goal of having all the renames in their own commit while preserving git-bisectability, with patch 3/6 containing the rename itself as generated by the Coccinelle script in [1]. Patch 2/6 is needed because sound/soc/mxs/mxs-saif.c calls both the consumer and the provider API. The actual implementation of the API split comes in patch 4/6. I will be happy to organize the refactoring differently if anybody has a better idea.
Patch 5/6 warns when there's an unbalanced usage of the enable and disable APIs, and patch 6/6 adds the API for setting floor and ceiling frequencies, per consumer.
