Subject: [PATCH 00/10] clk: mvebu: restructure SoC clock drivers

Marvell EBU SoCs share some common clock functions that register core
clocks or clock gates from SoC specific data. These clock drivers are
organized by function and over time the drivers filled up with #ifdefs
to separate different SoC specific code.

This patch set first adds a new element to clock gate descriptors to
allow to pass clk flags per clock gate. (Patch 1)

Then it restructures MVEBU clock drivers into common clock setup and
SoC specific files and Kconfig options. The driver's init functions
are also registered to get called with of_clk_init. (Patches 2, 3-6)

It then switches Dove, Kirkwood, and Armada 370/XP to make use of
of_clk_init instead of mvebu_clocks_init. (Patches 7-9)

Finally, all obsolete files and Kconfig options are removed. (Patch 10)

It has been tested on CuBox (Dove) and Dockstar (Kirkwood) by me.
Armada 370 and XP are compile tested only and should get their Tested-by
from Thomas and Gregory, respectively.

@Mike: As this only touches MVEBU related code, I suggest to take it
all through the corresponding ARM branch.

Sebastian Hesselbarth (10):
  clk: mvebu: introduce per-clock-gate flags
  clk: mvebu: add common clock functions for core clk and clk gating
  clk: mvebu: add Dove SoC-centric clock init
  clk: mvebu: add Kirkwood SoC-centric clock init
  clk: mvebu: add Armada 370 SoC-centric clock init
  clk: mvebu: add Armada XP SoC-centric clock init
  ARM: dove: move DT boards to SoC-centric clock init
  ARM: kirkwood: move DT boards to SoC-centric clock init
  ARM: mvebu: move DT boards to SoC-centric clock init
  clk: mvebu: desintegrate obsolete file
