Hi,

this version incorporates the feedback received in the first two versions. The only relevant changes are in the 3rd patch ("clk: use struct clk only for external API").

Not everything in arch/ builds yet, but Tegra and Exynos do build, and I have tested this in a Odroid U2.

Next I plan to fix any build issues, though of course I won't be able to test on all platforms (actually, most probably only on the Odroid U2).

Any opinions on the naming of struct clk_core will be much appreciated.

Thanks,

Tomeu

v2: * Rename provider API to e.g. clk_provider_set_rate as suggested by
Stephen
* Remove unnecessary error message on kzmalloc returning ENOMEM
* Have struct clk contain a pointer to struct clk_core as intended

v3: * Allocate and release the per-user struct clk
* Have clk_core_to_clk return any error it's passed, so calls to it can
be chained
* Add provider API for enable and disable
* Have clk_to_clk_core be an inline function to benefit of type-checking
* Have devres wrap the clk struct instead of clk_core
* Rename clk_core_to_clk to __clk_create_clk to make more clear that it
allocates

Tomeu Vizoso (5):
clk: Add temporary mapping to the existing API
clk: Move all drivers to use internal API
clk: use struct clk only for external API
clk: per-user clock accounting for debug
clk: Add floor and ceiling constraints to clock rates
