27c1ee3f92 Merge branch 'akpm' (Andrew's patch-bomb)
Merge Andrew's first set of patches:
 "Non-MM patches:

   - lots of misc bits

   - tree-wide have_clk() cleanups

   - quite a lot of printk tweaks.  I draw your attention to "printk:
     convert the format for KERN_<LEVEL> to a 2 byte pattern" which
     looks a bit scary.  But afaict it's solid.

   - backlight updates

   - lib/ feature work (notably the addition and use of memweight())

   - checkpatch updates

   - rtc updates

   - nilfs updates

   - fatfs updates (partial, still waiting for acks)

   - kdump, proc, fork, IPC, sysctl, taskstats, pps, etc

   - new fault-injection feature work"

9ec97169e7 Merge branch 'for-3.6' of git://gitorious.org/linux-pwm/linux-pwm
Pull PWM subsystem from Thierry Reding:
 "The new PWM subsystem aims at collecting all implementations of the
  legacy PWM API and to eventually replace it completely.

  The subsystem has been in development for over half a year now and
  many drivers have already been converted.  It has been in linux-next
  for a couple of weeks and there have been no major issues so I think
  it is ready for inclusion in your tree."

Arnd Bergmann <arnd@arndb.de>:
 "Very much Ack on the new subsystem.  It uses the interface
  declarations as the previously separate pwm drivers, so nothing
  changes for now in the drivers using it, although it enables us to
  change those more easily in the future if we want to.

  This work is also one of the missing pieces that are required to
  eventually build ARM kernels for multiple platforms, which is
  currently prohibited (amongs other things) by the fact that you cannot
  have more than one driver exporting the pwm functions."

4f2d658b2f arm-soc: device tree description updates
This branch contains two kinds of updates: Some platforms in the process
 of getting converted to device tree based booting, and the platform
 specific patches necessary for that are included here. Other platforms
 are already converted, so we just need to update the actual device
 tree source files and the binding documents to add support for new board
 and new drivers.
 In the future we will probably separate those into two branches, and
 in the long run, the plan is to move the device tree source files out
 of the kernel repository, but that has to wait until we have completed
 a much larger portion of the binding documents.

pwm_backlight_update_status calls the notify() and notify_after()
callbacks before and after applying the new PWM settings. However, if
brightness levels are used, the brightness value will be changed from
the index into the levels array to the PWM duty cycle length before
being passed to notify_after(), which results in inconsistent behavior.

373b436521 OMAPDSS: fix warnings if CONFIG_PM_RUNTIME=n
If runtime PM is not enabled in the kernel config, pm_runtime_get_sync()
will always return 1 and pm_runtime_put_sync() will always return
-ENOSYS. pm_runtime_get_sync() returning 1 presents no problem to the
driver, but -ENOSYS from pm_runtime_put_sync() causes the driver to
print a warning.

One option would be to ignore errors returned by pm_runtime_put_sync()
totally, as they only say that the call was unable to put the hardware
into suspend mode.

However, I chose to ignore the returned -ENOSYS explicitly, and print a
warning for other errors, as I think we should get notified if the HW
failed to go to suspend properly.

736f29cd6b OMAPDSS: Use PM notifiers for system suspend
The current way how omapdss handles system suspend and resume is that
omapdss device (a platform device, which is not part of the device
hierarchy of the DSS HW devices, like DISPC and DSI, or panels.) uses
the suspend and resume callbacks from platform_driver to handle system
suspend. It does this by disabling all enabled panels on suspend, and
resuming the previously disabled panels on resume.

This presents a few problems.

One is that as omapdss device is not related to the panel devices or the
DSS HW devices, there's no ordering in the suspend process. This means
that suspend could be first ran for DSS HW devices and panels, and only
then for omapdss device. Currently this is not a problem, as DSS HW
devices and panels do not handle suspend.

Another, more pressing problem, is that when suspending or resuming, the
runtime PM functions return -EACCES as runtime PM is disabled during
system suspend. This causes the driver to print warnings, and operations
to fail as they think that they failed to bring up the HW.

This patch changes the omapdss suspend handling to use PM notifiers,
which are called before suspend and after resume. This way we have a
normally functioning system when we are suspending and resuming the
panels.

This patch, I believe, creates a problem that somebody could enable or
disable a panel between PM_SUSPEND_PREPARE and the system suspend, and
similarly the other way around in resume. I choose to ignore the problem
for now, as it sounds rather unlikely, and if it happens, it's not
fatal.

In the long run the system suspend handling of omapdss and panels should
be thought out properly. The current approach feels rather hacky.
Perhaps the panel drivers should handle system suspend, or the users of
omapdss (omapfb, omapdrm) should handle system suspend.

Note that after this patch we could probably revert
0eaf9f52e9 (OMAPDSS: use sync versions of
pm_runtime_put). But as I said, this patch may be temporary, so let's
leave the sync version still in place.

2e063c305a OMAPDSS: DSI: Fix bug when calculating LP command interleaving parameters
In function dsi_compute_interleave_lp(), the escape clock/LP clock time period
is calculated incorrectly. The escape clock/LP clock is calculated as:

LP Clock(Hz) = DSI_FCLK(Hz) / lp_clk_div

Since we are calculating the time period of LP clock, the LP clock divider
should be multiplied with the time period of DSI_FCLK.

Calculating incorrect value of txclkesc results in incorrect calculation of LP
interleaving parameters, it also creates a possibility of a divide by zero
error.

5025ce070e OMAPDSS: fix bogus WARN_ON in dss_runtime_put()
pm_runtime_put_sync() in dss_runtime_put() returns -EBUSY when any child
of dss is still enabled. This happens, for example, when a display
output is enabled and one dumps the clocks via debugfs. This causes
dss_runtime_get & put to be called.

While I couldn't find anything about this in the documentation and it
wasn't immediately clear from runtime_pm code, it looks to me that
pm_runtime_put_sync() returns -EBUSY to inform that things went fine,
but the device could not be turned off as there are still child devices
that are enabled. This is not a problem.

This patch skips the WARN_ON if pm_runtime_put_sync() returns -EBUSY.

14674e7011 i2c: Split I2C_M_NOSTART support out of I2C_FUNC_PROTOCOL_MANGLING
Since there are uses for I2C_M_NOSTART which are much more sensible and
standard than most of the protocol mangling functionality (the main one
being gather writes to devices where something like a register address
needs to be inserted before a block of data) create a new I2C_FUNC_NOSTART
for this feature and update all the users to use it.

Also strengthen the disrecommendation of the protocol mangling while we're
at it.

In the case of regmap-i2c we remove the requirement for mangling as
I2C_M_NOSTART is the only mangling feature which is being used.
