[PATCH RESEND v8 0/2] Per-user clock constraints

[Tomeu Vizoso]

Hi,

I have rebased this on top of 3.19rc1 so all the cleanups have been dropped and only the meat remains.

The first patch actually moves the per-clock data that was stored in struct
clk to a new struct clk_core and adds references to it from both struct clk and
struct clk_hw. struct clk is now ready to contain information that is specific
to a given clk consumer.

The second patch adds API for setting floor and ceiling constraints and stores
that information on the per-user struct clk, which is iterable from struct
clk_core. The constraints are made available to clock implementations in the determine_rate callback.

A rough test module was used to test this:

Thanks,

Tomeu
