Milo Kim 5812c13a4e backlight: lp855x_bl: support new LP8555 device
LP8555 is one of the LP855x family devices.

This device needs pre_init_device() and post_init_device() driver
structure.  It's same as LP8557, so the device configuration code is
shared with LP8557.  Backlight outputs are generated from dual DC-DC boost
converters.  It's configurable EPROM settings which are defined in the
platform data.

Driver documentation and device tree bindings are updated.

Linus Torvalds 10d0c9705e DeviceTree updates for 3.13. This is a bit larger pull request than
usual for this cycle with lots of clean-up.
 
 - Cross arch clean-up and consolidation of early DT scanning code.
 - Clean-up and removal of arch prom.h headers. Makes arch specific
   prom.h optional on all but Sparc.
 - Addition of interrupts-extended property for devices connected to
   multiple interrupt controllers.
 - Refactoring of DT interrupt parsing code in preparation for deferred
   probe of interrupts.
 - ARM cpu and cpu topology bindings documentation.
 - Various DT vendor binding documentation updates.

Gu Zheng 3a41c5dbe8 fb: reorder the lock sequence to fix potential dead lock

50e244cc79 fb: rework locking to fix lock ordering on takeover
e93a9a8687 fb: Yet another band-aid for fixing lockdep mess
054430e773 fbcon: fix locking harder

reworked locking to fix related lock ordering on takeover, and introduced console_lock
into fbmem, but it seems that the new lock sequence(fb_info->lock ---> console_lock)
is against with the one in console_callback(console_lock ---> fb_info->lock), and leads to
a potential dead lock as following:

 *** DEADLOCK ***

so we reorder the lock sequence the same as it in console_callback() to
avoid this issue. And following Tomi's suggestion, fix these similar
issues all in fb subsystem.

Linus Torvalds 21604cdcdc ARM: SoC cleanups for 3.13
This branch contains code cleanups, moves and removals for 3.13.
 
 Qualcomm msm targets had a bunch of code removal for legacy non-DT
 platforms. Nomadik saw more device tree conversions and cleanup of old
 code. Tegra has some code refactoring, etc.
 
 One longish patch series from Sebastian Hasselbarth changes the init_time
 hooks and tries to use a generic implementation for most platforms,
 since they were all doing more or less the same things.
 
 Finally the "shark" platform is removed in this release. It's been
 abandoned for a while and nobody seems to care enough to keep it
 around. If someone comes along and wants to resurrect it, the removal
 can easily be reverted and code brought back.
 
 Beyond this, mostly a bunch of removals of stale content across the
 board, etc.

Bit a bit -fixes pull request in the merge window than usual dua to two
feauture-y things:
- Display CRCs are now enabled on all platforms, including the odd DP case
  on gm45/vlv. Since this is a testing-only feature it should ever hurt,
  but I figured it'll help with regression-testing -fixes. So I left it
  in and didn't postpone it to 3.14.
- Display power well refactoring from Imre. Would have caused major pain
  conflict with the bdw stage 1 patches if I'd postpone this to -next.
  It's only an relatively small interface rework, so shouldn't cause pain.
  It's also been in my tree since almost 3 weeks already.

That accounts for about two thirds of the pull, otherwise just bugfixes:
- vlv backlight fix from Jesse/Jani
- vlv vblank timestamp fix from Jesse
- improved edp detection through vbt from Ville (fixes a vlv issue)
- eDP vdd fix from Paulo
- fixes for dvo lvds on i830M
- a few smaller things all over

Note: This contains a backmerge of v3.12. Since the -internal branch
always applied on top of -nightly I need that unified base to merge bdw
patches. So you'll get a conflict with radeon connector props when pulling
this (and nouveau/master will also conflict a bit when Ben doesn't
rebase). The backmerge itself only had conflicts in drm/i915.

There's also a tiny conflict between Jani's backlight fix and your sysfs
lifetime fix in drm-next.

Helge Deller 0219132fe7 parisc: sticon - unbreak on 64bit kernel
STI text console (sticon) was broken on 64bit machines with more than
4GB RAM and this lead in some cases to a kernel crash.

Since sticon uses the 32bit STI API it needs to keep pointers to memory
below 4GB. But on a 64bit kernel some memory regions (e.g. the kernel
stack) might be above 4GB which then may crash the kernel in the STI
functions.

Additionally sticon didn't selected the built-in framebuffer fonts by
default. This is now fixed.

On a side-note: Theoretically we could enhance the sticon driver to
use the 64bit STI API. But - beside the fact that some machines don't
provide a 64bit STI ROM - this would just add complexity.

Framebuffers shouldn't be cached and it is usually very uncommon to read

ioremap_nocache() which is also fine.

David Herrmann 498f6d3660 simplefb: fix unmapping fb during destruction
Unfortunately, fbdev does not create its own "struct device" for
framebuffers. Instead, it attaches to the device of the parent layer. This
has the side-effect that devm_* managed resources are not cleaned up on
framebuffer-destruction but rather during destruction of the
parent-device. In case of fbdev this might be too late, though.
remove_conflicting_framebuffer() may remove fbdev devices but keep the
parent device as it is.

Therefore, we now use plain ioremap() and unmap the framebuffer in the
fb_destroy() callback. Note that we must not free the device here as this
might race with the parent-device removal. Instead, we rely on
unregister_framebuffer() as barrier and we're safe.

James Bates 55aa42f2e6 efifb: prevent null-deref when iterating dmi_list
The dmi_list array is initialized using gnu designated initializers, and
therefore may contain fewer explicitly defined entries as there are
elements in it. This is because the enum above with M_xyz constants
contains more items than the designated initializer. Those elements not
explicitly initialized are implicitly set to 0.

Now efifb_setup() loops through all these array elements, and performs
a strcmp on each item. For non explicitly initialized elements this will
be a null pointer:

This patch swaps the check order in the if statement, thus checks first
whether dmi_list[i].base is null.

Merge tag 'omap-for-v3.13/cm-scm-cleanup-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/cleanup

From Paul Walmsley <paul@pwsan.com> via Tony Lindgren:

Move some of the OMAP2+ CM and System Control Module direct
register accesses into CM- and System Control
Module-specific "drivers" underneath arch/arm/mach-omap2/.  This
is a prerequisite for moving this code out of arch/arm/mach-omap2/ into
drivers/.

Basic test logs are available here:

Huayi Li 1dea1fd092 pwm_backlight: avoid short blank screen while doing hibernation
Use SIMPLE_DEV_PM_OPS macro will initialize the member "freeze"
and "thaw" of pwm_backlight_pm_ops as below,
	.freeze = suspend_fn,
	.thaw = resume_fn,
then during the process of making hibernation snapshot, screen
will be blank at the moment of freezing, and then light at the
moment of thawing.
this is not the right user experience for suspending to disk.

so this patch drops freeze and thaw callback, make the LCD is
always lighting before the final shutdown.

Exynos Display Port can be used only for Exynos SoCs. In addition,
non-DT for EXYNOS SoCs is not supported from v3.11; thus, there is
no need to support non-DT for Exynos Display Port.

The 'include/video/exynos_dp.h' file has been used for non-DT
support and the content of file include/video/exynos_dp.h is moved
to drivers/video/exynos/exynos_dp_core.h. Thus, the 'exynos_dp.h'
file is removed. Also, 'struct exynos_dp_platdata' is removed,
because it is not used any more.

Mike Dunn 8f43e18e27 pwm-backlight: Allow for non-increasing brightness levels
Currently the driver assumes that the values specified in the
brightness-levels device tree property increase as they are parsed from
left to right.  But boards that invert the signal between the PWM output
and the backlight will need to specify decreasing brightness-levels.
This patch removes the assumption that the last element of the array is
the maximum value, and instead searches the array for the maximum value
and uses that in the duty cycle calculation.

This patch adds a pci stub driver to hyper-fb.  The hyperv framebuffer
driver will bind to the pci device then, so linux kernel and userspace
know there is a proper kernel driver for the device active.  lspci shows
this for example:

[root@dhcp231 ~]# lspci -vs8
00:08.0 VGA compatible controller: Microsoft Corporation Hyper-V virtual
VGA (prog-if 00 [VGA controller])
        Flags: bus master, fast devsel, latency 0, IRQ 11
        Memory at f8000000 (32-bit, non-prefetchable) [size=64M]
        Expansion ROM at <unassigned> [disabled]
        Kernel driver in use: hyperv_fb

Another effect is that the xorg vesa driver will not attach to the
device and thus the Xorg server will automatically use the fbdev
driver instead.
