[PATCH v3 0/6] Add CPU clock support for Armada 7K/8K

Hello,

This is the third version of a series allowing to manage the cpu
clock for Armada 7K/8K. For these SoCs, the CPUs share the same clock
by cluster, so actually the clock management is done at cluster level.

As for the other Armada 7K/8K clocks it is possible to have multiple
AP so here again we need to have unique name: the purpose of the second
patch is to share a common code which will be used in 3 drivers.

The last 2 patch enable the driver at dt and platform level and will
be applied through the mvebu subsystem.

Changelog v2->v3:
- Add back the first patch documenting the binding

Changelog v1->v2:
- Header cleanup
- Use unsigned int instead of it for cluster member of the ap_cpu_clk struct
- Use clk_hw instead of clk
- Use regmap_read_poll_timeout
- Use for_each_of_cpu_node
- Remove unnecessary WARN_ON()
- Remove headers from armada_ap_cp_helper.h
- Few other minor cleanup
