[PATCH 0/7] core, cpu and gated clocks for mvebu

[Andrew Lunn]

This patchset combines code from Gregory Clement, Sebastian
Hesselbarth and myself to implement core clks, cpu clock and gated
clocks on Marvel MVEBU SoCs.

The Armada 370/XP core clock code is a refactored version of the
already submitted and ACKed code from Gregory. It has been made to fit
inside a framework developed by Sebastian which can handle all MVEBU
SoCs. The Armarda 370/XP SoCs have more core clocks than the older SoCs, and
the framework needs to handle this. Rather than specify the clock
frequencies in DT, a Sample At Reset register is used, which describes
each core clock frequency.

Armarda XP is an SMP processor, with each CPU having its own
clock. Gregories code for this has been taken as is.

The Armarda 370/XP clock source has been converted to the common clock
framework.

Dove, Kirkword, and probably Armarda 370/XP have the ability to gate
clocks to various blocks. A clk-gate clock is created for each of the
gateable clocks on Dove and Kirkwood. Armarda 370/XP clock gates are
currently unimplemented. Dove and Kirkwood board-dt.c and DT
descriptions are then modified to make use of these clk gates.

This code has been tested on:

Kirkwood based QNAP TS219
Armarda 370 based mirabox
Armara XP based OpenBlocks

and by Sebastian on:

Dove based Cubox.

Andrew Lunn (1):
  ARM: Kirkwood: switch to DT clock providers

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

Sebastian Hesselbarth (3):
  clk: mvebu: add mvebu core clocks.
  clk: mvebu: add clock gating control provider for DT
  ARM: dove: switch to DT clock providers
