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.

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.

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.

Move probe out of __init section and don't use platform_driver_probe
which cannot be used with deferred probing.
Since commit e9354576 ("gpiolib: Defer failed gpio requests by default")
this driver might return -EPROBE_DEFER if a gpio_request fails.

The nice thing about devm_* is that the driver doesn't need to free the
resources but the driver core takes care about that. This also
simplifies the error path quite a bit and removes the wrong check for a
clock pointer being NULL.

The Cyber2000 frame buffer driver contains a block of code solely

Also remove the pointless #ifdef CONFIG_PCI as the Kconfig

We have a bug with omapdrm, where omapdrm calls dispc's pm_runtime
function in atomic context, and dispc's pm_runtime is not marked as
irq_safe:
BUG: sleeping function called from invalid context at drivers/base/power/runtime.c:952
Dispc's runtime PM callbacks are irq safe, so we can just set the
irq_safe flag to fix the issue.
However, in the long term, I'd rather have omapdrm manage the runtime PM
calls in a better way. Calling get/put for every small operation that
touches the dispc registers is very inefficient. It'd be better and
cleaner to have clear "in-use" and "not-in-use" states for dispc, so
that we don't need to do register context restore for small operations,
only to turn dispc off right afterwards.

While using HDMI connector driver with sil9022 encoder
came across issue where connector driver is probed first.
This resulted in error. A deffered probe solved this.
Most connector drivers need a encoder driver as their
video source. This patch ensures we do a probe defferal
if video source is not present for connector drivers.

This reverts the Linux for Workgroups thing. And no, before somebody
asks, we're not doing Linux95. Not for a few years, at least.
Sure, the flag added some color to the logo, and could have remained as
a testament to my leet gimp skills. But no. And I'll do this early, to
avoid the chance of forgetting when I'm doing the actual rc1 release on

Board updates for 3.12. Again, a bit of domain overlap with SoC and DT branches,
but most of this is around legacy code and board support. We've found that
platform maintainers have a hard time separating all of these out and might
move towards fewer branches for next release.
- Removal of a number of Marvell Kirkwood board files, since contents
is now common and mostly configured via DT.
- Device-tree updates for Marvell Dove, including irqchip and clocksource

This branch contains code cleanups, moves and removals for 3.12.
There's a large number of various cleanups, and a nice net removal of
13500 lines of code.
Highlights worth mentioning are:
- A series of patches from Stephen Boyd removing the ARM local timer API.
- Move of Qualcomm MSM IOMMU code to drivers/iommu.
- Samsung PWM driver cleanups from Tomasz Figa, removing legacy PWM driver
and switching over to the drivers/pwm one.
- Removal of some unusued auto-generated headers for OMAP2+ (PRM/CM).
There's also a move of a header file out of include/linux/i2c/ to
platform_data, where it really belongs. It touches mostly ARM platform
code for include changes so we took it through our tree.

Pull PTR_RET() removal patches from Rusty Russell:
"PTR_RET() is a weird name, and led to some confusing usage. We ended
up with PTR_ERR_OR_ZERO(), and replacing or fixing all the usages.
This has been sitting in linux-next for a whole cycle"
[ There are still some PTR_RET users scattered about, with some of them
possibly being new, but most of them existing in Rusty's tree too. We
have that
#define PTR_RET(p) PTR_ERR_OR_ZERO(p)
thing in <linux/err.h>, so they continue to work for now - Linus ]

Here's the big driver core pull request for 3.12-rc1.
Lots of tiny changes here fixing up the way sysfs attributes are
created, to try to make drivers simpler, and fix a whole class race
conditions with creations of device attributes after the device was
announced to userspace.
All the various pieces are acked by the different subsystem maintainers.

The polarities were being set to active low when fbdev was requesting active
high. This patch reverses it so that what is set into the LCD controller is
correct.

TI LCD controller version 2 adds some extra bits in a register to
increase the available size to represent horizontal timings. This
patch allows the fbdev driver to utilize those extra bits.
This will become important for driving an HDMI encoder from the lcd
controller where some of the VESA/CEA modes require quite large porches.

The LCD controller represents some of the timing fields with a 0
in the register representing 1. This was not taken into account
when these registers were being set. Interestingly enough not
all of the LCDC controller timing registers implement this representation
so carefully went through the technical reference manual to only "fix"
the correct timings.

The driver was mapping the wrong fbdev margins to the
front porch / back porch for both vertical and horizontal
timings.
This patch corrects it so that:
hfp = right margin
hbp = left margin
vbp = upper margin
vfp = lower margin
