84655b762a clk: versatile: Add device tree probing for IM-PD1 clocks
As we want to move these clocks over to probe from the device
tree we add a device tree probing path.

The old platform data path will be deleted once we have the
device tree overall code in place.

ba3fae06c7 ARM/clk: move the ICST library to drivers/clk
This moves the ICST clock divider helper library from
arch/arm/common to drivers/clk/versatile so it is maintained
with the other clock drivers.

We keep the structure as a helper library intact and do not
fuse it with the clk-icst.c Versatile ICST clock driver: there
may be other users out there that need to use this library for
their clocking, and then it will be helpful to keep the
library contained. (The icst.[c|h] files could just be moved
to drivers/clk/lib or a similar location to share the library.)

6d31e3b22e clk: versatile: Remove clk.h and clkdev.h includes
Clock provider drivers generally shouldn't include clk.h because
it's the consumer API. Remove the include here because this is a
provider driver. Also remove clkdev.h in files that aren't using
it and replace them with slab.h in files that were relying on the
implicit include of slab.h in clkdev.h.

222cb1bf18 clk: impd1: add pclk clocks
The IM-PD1 PrimeCells all have pclk assignments though this clock
cannot be controlled, and we need to provide this as a dummy
clock for the PL061 GPIO driver to probe, so let's assign it to
all the cells on the board.

a218d7fa3f clk/versatile: export symbols for impd1
The impd1 code on mach-integrator can be a loadable module,
so we have to export icst_clk_register, integrator_impd1_clk_init
and integrator_impd1_clk_exit.

cc0cc4ca09 ARM: integrator: localize the impd1.h header
As we move toward multiplatform support for the Integrator family
we need to localize all <mach/*> headers. This moves the impd1.h
header down to the machine folder, copying the the three defines
only used by the clock driver down into the clock driver.

bf6edb4bb1 clk: versatile: pass a parent to the ICST clock
As we want to actually define the parent frequency in the device
tree for the ICST clocks, modify the clock registration function
to take a parent argument.

8e048b9997 clk: versatile: fixup IM-PD1 clock implementation
Register both VCO clocks, give per-logical module unique names
to the clocks so we can have several IM-PD1's connected (in
theory). Implement all the fixed-factor clocks as children of
VCO2.

Tested by using the UARTs and the PL181 MMC block on the IM-PD1,
works flawlessly.

ae6e694ef5 clk: versatile: pass a name to ICST clock provider
When we have more than one of these clocks in a system (such as
on the IM-PD1) we need a mechanism to pass a name for the clock.
Refactor to add this as an argument.

70ee657714 clk: move IM-PD1 clocks to drivers/clk
The ARM IM-PD1 add-on module has a few clock of its own, let's
move also these down to the drivers/clk/versatile driver dir
and get rid of any remaining oldschool Integrator clocks.
