804d74abe2 drm: use drm_compat_ioctl for 32-bit apps
Most of the DRM drivers appear to be missing the .compat_ioctl file
operation entry necessary for 32-bit application compatibility.

This patch  uses drm_compat_ioctl for all drivers which don't have
their own, and which are using drm_ioctl for .unlocked_ioctl.

This leaves drivers/gpu/drm/psb/psb_drv.c unchanged; it has a custom
.unlocked_ioctl and will presumably need a custom .compat_ioctl as
well.

451023dc32 drm: remove the raw_edid field from struct drm_display_info
Neither the drm core nor any of the drivers really need the raw_edid field
of struct drm_display_info for anything. Instead of being useful, it
creates confusion about who is responsible for freeing the memory it points
to and setting the field to NULL afterwards, leading to memory leaks and
dangling pointers.

Remove the raw_edid field, and fix drivers as necessary.

43829731dd workqueue: deprecate flush[_delayed]_work_sync()
flush[_delayed]_work_sync() are now spurious.  Mark them deprecated
and convert all users to flush[_delayed]_work().

If you're cc'd and wondering what's going on: Now all workqueues are
non-reentrant and the regular flushes guarantee that the work item is
not pending or running on any CPU on return, so there's no reason to
use the sync flushes at all and they're going away.

This patch doesn't make any functional difference.

d7f1642c90 drm/exynos: add G2D driver
Changelog v3:
- use __u64 instead of pointer in ioctl struct.

The G2D is a 2D graphic accelerator that supports Bit Block Transfer.
This G2D driver is exynos drm specific and supports only G2D(version
4.1) of later Exynos series from Exynos4X12 because supporting DMA.

The G2D is performed by two tasks simply.
1. Configures the rendering parameters, such as foreground color and
   coordinates data by setting the drawing context registers.
2. Start the rendering process by setting thre relevant command
   registers accordingly.

The G2D version 4.1 supports DMA mode as host interface. User can make
command list to reduce HOST(ARM) loads. The contents of The command list
is setted to relevant registers of G2D by DMA.

The command list is composed Header and command sets and Tail.
- Header: The number of command set(4Bytes)
- Command set: Register offset(4Bytes) + Register data(4Bytes)
- Tail: Pointer of base address of the other command list(4Bytes)

By Tail field, the G2D can process many command lists without halt at
one go.

The G2D has following the rendering pipeline.
--> Primitive Drawing --> Rotation --> Clipping --> Bilinear Sampling
--> Color Key --> ROP --> Mask Operation --> Alpha Blending -->
Dithering --> FrameBuffer

And supports various operations from the rendering pipeline.
- copy
- fast solid color fill
- window clipping
- rotation
- flip
- 4 operand raster operation(ROP4)
- masking operation
- alpha blending
- color key
- dithering
- etc

User should make the command list to data and registers needed by
operation to use. The Exynos G2D driver only manages the command lists
received from user. Some registers needs memory base address(physical
address) of image. User doesn't know its physical address, so fills the
gem handle of that memory than address to command sets, then G2D driver
converts it to memory base address.

We adds three ioctls and one event for Exynos G2D.

- ioctls
DRM_EXYNOS_G2D_GET_VER: get the G2D hardware version
DRM_EXYNOS_G2D_SET_CMDLIST: set the command list from user to driver
DRM_EXYNOS_G2D_EXEC: execute the command lists setted to driver

- event
DRM_EXYNOS_G2D_EVENT: event to give notification completion of the
		      command list to user

The power and clocks turns on always in exynos hdmi and mixer driver,
but we should turn off the power and clocks of exynos hdmi and mixer
when the hdmi cable unplugged or when hdmi unused.

There are two interrupt to detect hotplug of hdmi cable - internal
interrupt and external interrupt. The internal interrupt can use only
when hdmi is dpms on so if hdmi is dpms off, we should use external
interrupt to detect hotplug of hdmi cable. If hdmi is dpms on, we cannot
external interrupt because the gpio pin for external interrupt is used
to hdmi HPD pin for internal interrupt.

6be5ceb02e VM: add "vm_mmap()" helper function
This continues the theme started with vm_brk() and vm_munmap():
vm_mmap() does the same thing as do_mmap(), but additionally does the
required VM locking.

This uninlines (and rewrites it to be clearer) do_mmap(), which sadly
duplicates it in mm/mmap.c and mm/nommu.c.  But that way we don't have
to export our internal do_mmap_pgoff() function.

Some day we hopefully don't have to export do_mmap() either, if all
modular users can become the simpler vm_mmap() instead.  We're actually
very close to that already, with the notable exception of the (broken)
use in i810, and a couple of stragglers in binfmt_elf.

be53bfdb80 Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm main changes from Dave Airlie:
 "This is the main drm pull request, I'm probably going to send two more
  smaller ones, will explain below.

  This contains a patch that is also in the fbdev tree, but it should be
  the same patch, it added an API for hot unplugging framebuffer
  devices, and I need that API for a new driver.

  It also contains some changes to the i2c tree which Jean has acked,
  and one change to moorestown platform stuff in x86.

  Highlights:
   - new drivers: UDL driver for USB displaylink devices, kms only,
     should support correct hotplug operations.
   - core: i2c speedups + better hotplug support, EDID overriding via
     firmware interface - allows user to load a firmware for a broken
     monitor/kvm from userspace, it even has documentation for it.
   - exynos: new HDMI audio + hdmi 1.4 + virtual output driver
   - gma500: code cleanup
   - radeon: cleanups, CS optimisations, streamout support and pageflip
     fix
   - nouveau: NVD9 displayport support + more reclocking work
   - i915: re-enabling GMBUS, finish gpu patch (might help hibernation
     who knows), missed irq fixes, stencil tiling fixes, interlaced
     support, aliasesd PPGTT support for SNB/IVB, swizzling for SNB/IVB,
     semaphore fixes

  As well as the usual bunch of cleanups and fixes all over the place.

  I've got two things I'd like to merge a bit later:

   a) AMD support for all their new radeonhd 7000 series GPU and APUs.
      AMD dropped this a bit late due to insane internal review
      processes, (please AMD just follow Intel and let open source guys
      ship stuff early) however I don't want to penalise people who own
      this hardware (since its been on sale for 3-4 months and GPU hw
      doesn't exactly have a lifetime in years) and consign them to
      using closed drivers for longer than necessary.  The changes are
      well contained and just plug into the driver new gpu functionality
      so they should be fairly regression proof.  I just want to give
      them a bit of a run on the hw AMD kindly sent me.

   b) drm prime/dma-buf interface code.  This is just infrastructure
      code to expose the dma-buf stuff to drm drivers and to userspace.
      I'm not planning on pushing any driver support in this cycle
      (except maybe exynos), but I'd like to get the infrastructure code
      in so for the next cycle I can start getting the driver support
      into the individual drivers.  We have started driver support for
      i915, nouveau and udl along with I think exynos and omap in
      staging.  However this code relies on the dma-buf tree being
      pulled into your tree first since it needs the latest interfaces
      from that tree.  I'll push to get that tree sent asap.

  (oh and any warnings you see in i915 are gcc's fault from what anyone
  can see)."

Fix up trivial conflicts in arch/x86/platform/mrst/mrst.c due to the new
msic_thermal_platform_data() thermal function being added next to the
tc35876x_platform_data() i2c device function..

132a5b915f drm/exynos: remove module of exynos drm subdrv
The exynos drm driver has several subdrv. They each can be module but it
causes unfixed probe order of exynodr drm driver and each subdrv. It
also needs some weird codes such as exynos_drm_fbdev_reinit and
exynos_drm_mode_group_reinit. This patch can remove weird codes and
clear codes through we doesn't modularity each subdrv.

Also this removes unnecessary codes related module.

this function would be used for drm based 2d acceleration driver
to get/put dma address through gem handle.
when exynos_drm_get_dma_address is called reference count of
gem object would be increased not to be released by gem close and
when exynos_drm_put_dma_address is called the reference count of
this gem object would be decreased to be released.

f7d86075fa drm/exynos: Fix fb_videomode <-> drm_mode_modeinfo conversion
The fb_videomode structure stores the front porch and back porch in the
right_margin and left_margin fields respectively. right_margin should
thus be computed with hsync_start - hdisplay, and left_margin with
htotal - hsync_end. The same holds for the vertical direction.

0d8ce3ae37 drm/exynos: fix runtime_pm fimd device state on probe
A call to pm_runtime_set_active() forces device to be at the active
state and skips calling its runtime suspend/resume callbacks. This
results in a freeze with a new power domain code based on gen_pd. Fimd
driver does all required runtime power management calls, so this
pm_runtime_set_active call is buggy. This patch removes it and corrects
clock management in probe function (clocks are now enabled by
pm_runtime_get_sync() call).

9866b6c64b drm/exynos: use correct 'exynos-drm' name for platform device
Currently Exynos DRM driver uses DRIVER_NAME ('exynos') name for the
core platform device. This is confusing, because it doesn't refer to the
function the platform device is performing. This patch renames the
platform device to the 'exynos-drm', which matches the convention for
naming the platform devices. The name used inside DRM subsystem has not
been changed.

Talking to Al Viro on irc, we can see no possible reason for doing
this, the upper mmap code does it. The code has been there since
first import into drm tree I can find.

Al tracked down this as a requirement pre 2.3.51 hasn't been needed since.
