'struct omap_video_timings' was updated w/ a 'bool interlaced'. Without
a matching update in omap_connector, this field could have undefined
values from the stack, which isn't quite ideal.
Update the fxns to convert omapdss<->drm timings structs, and zero-init
'struct omap_video_timings' when it is declared on stack to avoid issues
like this in the future.

The reclaim_buffers callback has already been removed by Daniel Vetter
<daniel.vetter@ffwll.ch> with his patch "drm: kill reclaim_buffers callback"
(b0071efe82). As a result the kernel compilation fails with omapdrm support
and so the callback for reclaim_buffers is being removed from omapdrm.

"Here's the big staging tree merge for the 3.6-rc1 merge window.
There are some patches in here outside of drivers/staging/, notibly

Pull main drm updates from Dave Airlie:
"This is the main merge window request for the drm.
It's big, but jam packed will lots of features and of course 0
regressions. (okay maybe there'll be one).
Highlights:
- new KMS drivers for server GPU chipsets: ast, mgag200 and cirrus
(qemu only). These drivers use the generic modesetting drivers.
- initial prime/dma-buf support for i915, nouveau, radeon, udl and
exynos
- switcheroo audio support: so GPUs with HDMI can turn off the sound
driver without crashing stuff.
- There are some patches drifting outside drivers/gpu into x86 and
EFI for better handling of multiple video adapters in Apple Macs,
they've got correct acks except one trivial fixup.
- Core:
edid parser has better DMT and reduced blanking support,
crtc properties,
plane properties,
- Drivers:
exynos: add 2D core accel support, prime support, hdmi features
intel: more Haswell support, initial Valleyview support, more
hdmi infoframe fixes, update MAINTAINERS for Daniel, lots of
cleanups and fixes
radeon: more HDMI audio support, improved GPU lockup recovery
support, remove nested mutexes, less memory copying on PCIE, fix
bus master enable race (kexec), improved fence handling
gma500: cleanups, 1080p support, acpi fixes
nouveau: better nva3 memory reclocking, kepler accel (needs
external firmware rip), async buffer moves on nv84+ hw.
I've some more dma-buf patches that rely on the dma-buf merge for vmap
stuff, and I've a few fixes building up, but I'd decided I'd better
get rid of the main pull sooner rather than later, so the audio guys
are also unblocked."

This patch splits the DMM off into a separate sub-device, in order to
utilize the platform device information that was created as part of
the OMAP hwmod entry for the DMM.
The driver probe function queries the iomem resource and IRQ using
standard platform_get functions.
The OMAP DRM driver now calls the platform_driver_register() function
for the subordinate DMM driver inside its probe function. This
guarantees the required order for the DMM and ensures the DMM resources
are available for use by the DRM driver.

Add support in framebuffer objects for other color formats and multi-
planar YUV (NV12). Since this requires changing the API between the
plane and fb for getting scanout information (paddr, etc), take
advantage of the opportunity and put in place a way to allow fb's to
be unpinned when they are not being scanned out. Now, before start
of scanout the plane calls omap_framebuffer_pin() which takes care
to pin all the backing bo's, then omap_framebuffer_update_scanout()
however many times to update the scanout address(es), etc, and then
when finished omap_framebuffer_unpin().
