Kuninori Morimoto db6668d83a fbdev: sh_mobile_hdmi: 32bit register access support
Latest SuperH HDMI allows 32bit access only.
But the data is 8bit. So, we can keep compatibility by switching 8/32 bit access.

Heiko Stübner 1f45f9dbb3 fb_defio: add first_io callback
With this optional callback the driver is notified when the first page
is entered into the pagelist and a new deferred_io call is scheduled.

A possible use-case for this is runtime-pm. In the first_io call
	pm_runtime_get()
could be called, which starts an asynchronous runtime_resume of the
device. In the deferred_io callback a call to
	pm_runtime_barrier()
makes the sure, the device is resumed by then and a
	pm_runtime_put()
may put the device back to sleep.

Also, some SoCs may use the runtime-pm system to determine if they
are able to enter deeper idle states. Therefore it is necessary to
keep the use-count from the first written page until the conclusion
of the screen update, to prevent the system from going to sleep before
completing the pending update.

Two users of defio were using kmalloc to allocate the structure.
These allocations are changed to kzalloc, to prevent uninitialised
.first_io members in those drivers.

The video interface timing is independent of the window setup data.
The resolution of the window can be smaller than that of the lcd
panel to which the video data is output.

So move the video timing data from the per-window setup data to the
platform specific section in the platform data. This also removes
the restriction that atleast one window should have the same
resolution as that of the panel attached.

Ondrej Zary ef798d0207 kyrofb: fix on x86_64
kyrofb is completely broken on x86_64 because the registers are defined as
unsigned long. Change them to u32 to make the driver work.
Tested with Hercules 3D Prophet 4000XT.

Linus Torvalds f4e52e7ffd regmap: A couple of small fixes for 3.4
Two more small fixes:
 - Now we have users for it that aren't running Android it turns out that
   regcache_sync_region() is much more useful to drivers if it's exported
   for use by modules.  Who knew?
 - Make sure we don't divide by zero when doing debugfs dumps of rbtrees,
   not visible up until now because everything was providing at least
   some cache on startup.
