7314e613d5 Fix a few incorrectly checked [io_]remap_pfn_range() calls
Nico Golde reports a few straggling uses of [io_]remap_pfn_range() that
really should use the vm_iomap_memory() helper.  This trivially converts
two of them to the helper, and comments about why the third one really
needs to continue to use remap_pfn_range(), and adds the missing size
check.

fb8a15079a video: mmp: drop needless devm cleanup
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.

48664b21ae OMAPDSS: DISPC: set irq_safe for runtime PM
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.

0fd9560257 OMAPDSS: Return right error during connector probe
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.

d5d04bb48f Bye, bye, WfW flag
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.

44598f98b9 ARM: SoC board updates for 3.12
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.
 - Shuffling of some of the new Broadcom platforms to give room for others in
   the same mach directory. More in 2.13.

8e73e367f7 ARM: SoC cleanups for 3.12
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.

 "I've got this pull request separate from the main fbdev pull request,
  as this contains a bunch of OMAP board file changes and thus could
  possibly be rejected in case of bad conflicts.

  The removal of the old display drivers depend on the board file
  changes, so Tony Lindgren suggested taking them together via fbdev
  tree.  These are in linux-next, and also Tony didn't see any conflicts
  with any of the branches he had, so they should go in clean.

   - Change the OMAP board files to use the new OMAP display drivers

   - Remove all the old drivers, and the related auxiliary code"

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.

9560dc1059 OMAPDSS: rename omap_dss_device's 'device' field to 'dst'
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.

a73fdc6474 OMAPDSS: rename omap_dss_device's 'output' to 'src'
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

7d27becb35 video/hdmi: Introduce helpers for the HDMI vendor specific infoframe
Provide the same programming model than the other infoframe types.

The generic _pack() function can't handle those yet as we need to move
the vendor OUI in the generic hdmi_vendor_infoframe structure to know
which kind of vendor infoframe we are dealing with.

v3: Future proof the sending of 3D_Ext_Data (Ville Syrjälä), Fix
    multi-lines comment style (Thierry Reding)

a5ad3dcf35 video/hdmi: Don't let the user of this API create invalid infoframes
To set the active aspect ratio value in the AVI infoframe today, you not
only have to set the active_aspect field, but also the active_info_valid
bit. Out of the 1 user of this API, we had 100% misuse, forgetting the
_valid bit. This was fixed in:

We can do better and derive the _valid bit from the user wanting to set

3825ce5a9b OMAPDSS: fix WARN_ON in 'alpha_blending_enabled' sysfs file
The code handling 'alpha_blending_enabled' sysfs file contains WARN_ONs
in case the feature is not supported on the current platform. Even
though only root can write to the file, anyone can read it, thus causing
the kernel to get tainted and printing an ugly warning.

Instead of having WARN_ONs, return a proper error if the feature is not
supported.

db680c6515 OMAPDSS: HDMI: Fix possible NULL reference
Commit 5391e87d12 (OMAPDSS: remove dispc's dependency to VENC/HDMI)
introduced a possible NULL reference bug in the HDMI driver when setting
timings. In practice the bug shouldn't happen, as the timings have been
verified earlier, and thus the timings should always be ok.

Fix the possible issue by moving the use of the timings pointer inside
the NULL check.
