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.

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
the road.

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
setup.
- Defconfig updates. Gotta go somewhere. One new one for Renesas Lager.
- New backlight drivers for backlights used on Renesas shmobile platforms.
- Removal of Renesas leds driver.

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.

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.

In the old panel device model we had omap_dss_output entities,
representing the encoders in the DSS block. This entity had "device"
field, which pointed to the panel that was using the omap_dss_output.
With the new panel device model, the omap_dss_output is integrated into
omap_dss_device, which now represents a "display entity". Thus the "device"
field, now in omap_dss_device, points to the next entity in the display
entity-chain.
This patch renames the "device" field to "dst", which much better tells
what the field points to.

In the old panel device model we had "outputs", which were the encoders
inside OMAP DSS block, and panel devices (omap_dss_device). The panel
devices had a reference to the source of the video data, i.e. reference
to an "output", in a field named "output".
That was somewhat confusing even in the old panel device model, but even
more so with the panel device model where we can have longer chains of
display entities.
This patch renames the "output" field to "src", which much better tells
what the field points to.
