Subject: [PATCH V3 0/3]  Add clock framework for armada 370/XP

Hello Mike,

The v3.7-rc1 was released yesterday. So here it is the updated version
of my patch set. The rebase was flawless. An I have just fixed a typo
in the device tree and warnings from checkpatch. I built and test it
for the Armada 370 and Armada XP evaluation board.

The purpose of this patch set is to add support for clock framework
for Armada 370 and Armada XP SoCs. All the support is done under the
directory drivers/clk/mvebu/ as the support for other mvebu SoCs was
in mind during the writing of the code.

Two kinds of clocks are added:

- The CPU clocks are only for Armada XP (which is multi-core)

- The core clocks are clocks which have their rate fixed during
  reset.

Many thanks to Thomas Petazzoni and Sebastian Hesselbarth for their
review and feedback. The device tree bindings were really improved
with the advices of Sebastian.

Changelog:
V2 -> V3:
- Rebased on top of v3.7-rc1
- Fixed a typo in device trees
- Fixed warning from checkpatch

V1 -> V2:

- Improved the spelling and the wording of the documentation and the
  1st commit log
- Removed the "end_of_list" name which are unused here.
- Fix the cpu clock by using of_clk_src_onecell_get in the same way it
  was used for the core clocks

Regards,


Gregory CLEMENT (3):
  clk: mvebu: add armada-370-xp specific clocks
  clk: armada-370-xp: add support for clock framework
  clocksource: time-armada-370-xp converted to clk framework
