[PATCH v11 0/4] Per-user clock constraints

[Tomeu Vizoso]

Hi,

in this v11 I have restored the possibility of orphaning a clock by passing NULL to clk_set_parent and have fixed the free sequence of per-user clk structs.

The first patch just removes some unneeded NULL checks.

The second 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 third 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.

The fourth patch adds a module that can be used to unit-test the CCF. It's very rough right now, but I hope to have time soon to polish it a bit. It has been quite useful during development of this series though.

Thanks,
