f9cfa63051 clk: remove use of __devexit_p
CONFIG_HOTPLUG is going away as an option so __devexit_p is no longer

1f61e5f143 clk: clock multiplexers may register out of order
When a clock, C is initialised any orphan clocks listing C as
a possible parent are reparented to it regardless of the
parent requested by the orphan's get_parent() operation.

This means that multiplexers registered before their parents
are reparented to the first parent subsequently declared,
regardless of the selection made by the hardware registers.

For example:
	static const char *sel[] = { "srcA", "srcB", "dummy", "srcC" };

	child = clk_register_mux(NULL, "child",  sel, ARRAY_SIZE(sel), ...);
	clk_register_fixed(NULL, "dummy", ...);
	clk_register_fixed(NULL, "srcA", ...);
	clk_register_fixed(NULL, "srcB", ...);
	clk_register_fixed(NULL, "srcC", ...);

Causes child's parent to always be "dummy".

To fix this, when an orphanned clock has a get_parent() operation,
only reparent to the clock indicated by get_parent().

45228ef322 clk: ux500: Initial support for abx500 clock driver
The abx500 clock driver is a platform driver which will be initialized
during arch init. The platform device shall be added from the ab-core
driver as a mfd child device to maintain correct boot sequence.

Depending on what ab version we use, different clock definitions will
be added.

Merging in mainline back to next/cleanup since it has collected a few

Git doesn't auto-resolve some of them, and they're mostly noise so let's
take care of it locally.

just touching two registers, and in the same way as well: one

that makes it possible to write to the VCO.

Factor this register read/write into the ICST driver so we can

973e1d1de0 CLK: vt8500: Fix SDMMC clk special cases
This patch adds some additional handling for the SDMMC special case
in round_rate and set_rate which results in invalid divisor messages
at boot time.

0de9f23a28 clk: fix return value check in bcm2835_init_clocks()
In case of error, the function clk_register_fixed_rate() returns
ERR_PTR() and never returns NULL. The NULL test in the return value
check should be replaced with IS_ERR().

d6e99fa4f4 clk: ux500: Add armss clk and fixup smp_twd clk for u8500
The new armss clk is a prcmu_scalable_rate clk which represents
the ARMSS clk. This then makes it possible to convert the smp_twd
clk to a fixed factor clock type, using a fixed divider of 2 and
with the armss clk as parent.

b7a5bcd5cd clk/ux500: explicitly include register header
The ux500 clock driver file named u8500_clk.c does not compile
if it loose implicit dependencies to <mach/db8500-regs.h>
(I have no clue what files will include this) which manifests
itself as I'm experimenting with SPARSE_IRQ so make the
dependency explicit.

46c8773a58 clk: Add devm_clk_{register,unregister}()
Some clock drivers can be simplified if devres takes care of
unregistering any registered clocks along error paths. Introduce
devm_clk_register() so that clock drivers get unregistration for
free along with simplified error paths.
