2885c3b2a3 clk: Show correct information when fail to set clock rate
This patch shows the correct information for debugging when fail
to set clock rate because original error message shows the error
value instead of current clock rate.

64a12c56ad clk: Kconfig: Move bcm Kconfig into clk menu
Having this Kconfig sourced outside the clk menu means the option
is under the "Device Drivers" menu instead of the "Common Clock
Framework" menu. Move it so that the bcm clock config options are
in the right place.

5e1d012851 ARM: pxa: change clocks init sequence
Since pxa clocks were ported to the clock framework, an ordering issue
appears between clocks and clocksource initialization. As a consequence,
the pxa timer clock cannot be acquired in pxa_timer, and is disabled by
clock framework because it is "unused".

The ordering issue is that in the kernel boot sequence :
  start_kernel()
    ...
    time_init()
      -> pxa_timer()
        -> here the clocksource is initialized
    ...
    rest_init()
      kernel_init()
	initcalls
	  -> here the clocks are initialized

In the current sequence, the clocks are initialized way after pxa_timer,
which cannot acquire the OSTIMER0 clock.

To solve this issue, the clocks initialization is moved to pxa_timer(),
so that clocks are initialized before clocksource for non device-tree.
For device-tree, the standard arm time_init() will take care of the
ordering.

0cd3be6e9a clk: si5351: Do not pass struct clk in platform_data
When registering clk-si5351 by platform_data, we should not pass struct clk
for the reference clocks. Drop struct clk from platform_data and rework the
driver to use devm_clk_get of named clock references.

While at it, check for at least one valid input clock and properly prepare/
enable valid reference clocks.

a633472519 clk: Add some more lockdep assertions
We don't check to make sure the enable_lock is held across
enable/disable and we don't check if the prepare_lock is held
across prepare/unprepare. Add some asserts to catch any future
locking problems.

70e9f4dde0 clk: add newline character after dumping all clocks

d2a5d46b16 clk: add missing lock when call clk_core_enable in clk_set_parent
Before commit 035a61c314eb ("clk: Make clk API return per-user
struct clk instances") we acquired the enable_lock in
__clk_set_parent_{before,after}() by means of calling
clk_enable(). After commit 035a61c314eb we use clk_core_enable()
in place of the clk_enable(), and clk_core_enable() doesn't
acquire the enable_lock. This opens up a race condition between
clk_set_parent() and clk_enable(). Fix it.

Add a helper to allocate and add a clk_lookup structure.  This can not
only be used in several places in clkdev.c to simplify the code, but
more importantly, can be used by callers of the clkdev code to simplify
their clkdev creation and registration.

d5622a9c13 clkdev: use clk_hw internally
clk_add_alias() calls clk_get() followed by clk_put() but in between
those two calls it saves away the struct clk pointer to a clk_lookup
structure. This leaves the 'clk' member of the clk_lookup pointing at
freed memory on configurations where CONFIG_COMMON_CLK=y. This is a
problem because clk_get_sys() will eventually try to dereference the
freed pointer by calling __clk_get_hw() on it. Fix this by saving away
the struct clk_hw pointer instead of the struct clk pointer so that when
we try to create a per-user struct clk in clk_get_sys() we don't
dereference a junk pointer.
