4390e62260 ARM: imx6: Derive spdif clock from pll3_pfd3_454m
SPDIF can derive a TX clock for playback from one of its clock sources --
spdif root clock to match its supporting sample rates. So this patch set
the spdif root clock's parent to pll3_pfd3_454m since the pll3_pfd3_454m
can approximately meet its sample rate requirement.

10471fa3c7 ARM i.MX5: set CAN peripheral clock to 24 MHz parent
This patch sets the parent of CAN peripheral clock (a.k.a. CPI clock) to the
lp_apm clock, which has a rate of 24 MHz.

In the CAN world a base clock with multiple of 8 MHz is suited best for all CIA
recommented bit rates. Without this patch the CAN peripheral clock on i.MX53
has a rate of 66.666 MHz which produces quite large bit rate errors.

374daac46f ARM: imx: add support code for IMX50 based machines
Add machine support code for the Freescale IMX50 SoC.

The IMX50 is quite similar to the Freescale IMX53, and contains many of the
same periperhal hardware modules, at the same address offsets as the IMX53.
(Notable exceptions are that the IMX50 contains no CAN bus hardware, less
GPIO, no VPU, it does contain an Electrophoretic display controller though).

This support code uses some of the IMX53 setup code to reduce duplication
of what would be identical init IO setup.

843f4f4bb1 A regression showed up that there's a large delay when enabling
all events. This was prevalent when FTRACE_SELFTEST was enabled which
 enables all events several times, and caused the system bootup to
 pause for over a minute.
 
 This was tracked down to an addition of a synchronize_sched() performed
 when system call tracepoints are unregistered.
 
 The synchronize_sched() is needed between the unregistering of the
 system call tracepoint and a deletion of a tracing instance buffer.
 But placing the synchronize_sched() in the unreg of *every* system call
 tracepoint is a bit overboard. A single synchronize_sched() before
 the deletion of the instance is sufficient.

002acf1fc1 Power management fixes for 3.13-rc3
- cpufreq regression fix from Bjørn Mork restoring the pre-3.12
    behavior of the framework during system suspend/hibernation to
    avoid garbage sysfs files from being left behind in case of a
    suspend error.
 
  - PNP regression fix to restore the correct states of devices after
    resume from hibernation broken in 3.12.  From Dmitry Torokhov.
 
  - cpuidle fix to prevent cpuidle device unregistration from crashing
    due to a NULL pointer dereference if cpuidle has been disabled
    from the kernel command line.  From Konrad Rzeszutek Wilk.
 
  - intel_idle fix for the C6 state definition on Intel Avoton/Rangeley
    processors from Arne Bockholdt.
 
  - Power capping framework fix to make the energy_uj sysfs attribute
    work in accordance with the documentation.  From Srinivas Pandruvada.
 
  - epoll fix to make it ignore the EPOLLWAKEUP flag if the kernel has
    been compiled with CONFIG_PM_SLEEP unset (in which case that flag
    should not have any effect).  From Amit Pundir.
 
  - cpufreq fix to prevent governor sysfs files from being lost over
    system suspend/resume in some (arguably unusual) situations.  From
    Viresh Kumar.

3ccb012392 tracing: Only run synchronize_sched() at instance deletion time
It has been reported that boot up with FTRACE_SELFTEST enabled can take a
very long time. There can be stalls of over a minute.

This was tracked down to the synchronize_sched() called when a system call
event is disabled. As the self tests enable and disable thousands of events,
this makes the synchronize_sched() get called thousands of times.

The synchornize_sched() was added with d562aff93b "tracing: Add support
for SOFT_DISABLE to syscall events" which caused this regression (added
in 3.13-rc1).

The synchronize_sched() is to protect against the events being accessed
when a tracer instance is being deleted. When an instance is being deleted
all the events associated to it are unregistered. The synchronize_sched()
makes sure that no more users are running when it finishes.

Instead of calling synchronize_sched() for all syscall events, we only
need to call it once, after the events are unregistered and before the
instance is deleted. The event_mutex is held during this action to
prevent new users from enabling events.
