driver change clk_get fails on am335x.

Configure below LCDC configurations to optimal values, also have an
option configure these optional parameters for platform.
1) AC bias configuration: Required only for passive panels
2) Dma_burst_size:
3) FIFO_DMA_DELAY:
4) FIFO threshold: Does not apply for da830 LCDC.

Patch is verified for 16bpp and 24bpp configurations on da830, da850 and
am335x EVMs.

Although the DIU driver creates five framebuffer devices, only the first
one controls the physical display.  The remaining four are virtual "AOIs".
Therefore, the EDID data should be stored in the global fsl_diu_data
object, instead of the per-framebuffer object.

We don't use the writeback buffer, so don't initialize the registers for
that feature.

The default value for SYN_POL is already zero, so don't re-initialize it.

Writing the INT_STATUS register does nothing.

The value that we write to the PLUT register only makes sense on the
MPC8610 and P1022, so don't touch that register on the MPC5121.

Commit 4b5006ec ("shared DIU framebuffer support") added the ability to
retain the splash screen until the framebuffer is opened by user space.
Clean up this code to eliminate redundant writes to registers, and eliminate
the use of dummy area descriptor.

Remove functions request_irq_local() and free_irq_local(), and merge
their code into the functions that handle opening and closing the
framebuffer.  We also improve the way that interrupts are enabled.

Also implement a work-around for broken U-Boots that leave the DIU
interrupts enabled.

The MPC5121 BSP comes with a gamma_set utility that initializes the gamma
table via an ioctl.  Unfortunately, the ioctl number that utility uses
is defined improperly, but we can still support it.

Allow the platform code not to define a value for diu_ops.set_monitor_port.
This would be for platforms that only have one monitor port.
set_monitor_port() will never be called with an unsupported port anyway.

Green pixel and blue pixel are 3 bits and 2 bits respectively
at ARGB232 format. Thus, the value of red offset should be 5,
not 4. Also, the value of red length should be 2, because
red pixel is 2 bits at ARGB232 format.

Because there is no need to access to the platform device in

This patch uses FIMD_V8_VIDTCON0 as the address definition

So, FIMD_V8_VIDTCON0 should be used.

Pull powerpc EEH bugfixes from Benjamin Herrenschmidt.

Two one-liner fixes for the new EEH code.

* 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc:
  powerpc/eeh: Do not invalidate PE properly
  powerpc/pseries: Fix oops with MSIs when missing EEH PEs

Pull MIPS fixes from Ralf Baechle:
 "Three issues fixed accross the field:

   - Some functions that were recently outlined as part of a preemption
     fix were causing problems with function tracing.
   - The recently merged in-kernel MPI library uses very outdated
     headers that contain MIPS-specific code which won't build on with
     gcc 4.4 or newer.
   - The MIPS non-NUMA memory initialization was making only a very
     half-baked attempt at merging adjacent memory ranges.  This kept
     the code simple enough but is now causing issues with kexec."

* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
  MPI: Fix compilation on MIPS with GCC 4.4 and newer
  MIPS: Fix crash that occurs when function tracing is enabled
  MIPS: Merge overlapping bootmem ranges

While the EEH does recovery on the specific PE that has PCI errors,
the PCI devices belonging to the PE will be removed and the PE will
be marked as invalid since we still need the information stored in
the PE. We only invalidate the PE when it doesn't have associated
EEH devices and valid child PEs. However, the code used to check
that is wrong. The patch fixes that.

Pull MTD fixes from David Woodhouse:
 "The most important part of this is that it fixes a regression in
  Samsung NAND chip detection, introduced by some rework which went into
  3.7.  The initial fix wasn't quite complete, so it's in two parts.  In
  fact the first part is committed twice (Artem committed his own copy
  of the same patch) and I've merged Artem's tree into mine which
  already had that fix.

  I'd have recommitted that to make it somewhat cleaner, but figured by
  this point in the release cycle it was better to merge *exactly* the
  commits which have been in linux-next.

  If I'd recommitted, I'd also omit the sparse warning fix.  But it's
  there, and it's harmless — just marking one function as 'static' in
  onenand code.

  This also includes a couple more fixes for stable: an AB-BA deadlock
  in JFFS2, and an invalid range check in slram."
