The driver can be built as either a PCI or platform (OF) driver. It
might make sense to built it as both (though that is not currently
possible) but it certainly doesn't make sense to build it as neither!
Add dependencies and add a choice group to ensure that exactly one of
FB_MB862XX_PCI_GDC and FB_MB862XX_LIME is selected.

Add the support for NV12 color format.
Configure base address for UV component of NV12 color format.
Change the way chroma scaling is handled for YUV formats on OMAP4 by enabling
chroma-resampling for video pipeline and hence using FIR2 register set for
scaling UV.
Changes to _dispc_set_scaling(), because of the reason above, are:
- call _dispc_set_scaling_common() to handle scaling for all color formats
except for OMAP4 where it only handles scaling for RGB or Y-component
- call _dispc_set_scaling_uv() for special handling required for UV
component on OMAP4.
- dispc_set_scaling_uv() also resets chroma-resampling bit for RGB color modes.
Contains chroma scaling (_dispc_set_scaling_uv) design and implemented by

Add new registers specific to UV color component that are introduced in OMAP4.
Add simple helper functions to configure the newly added registers.
These new registers are mainly:
- UV base address registers used specifically for NV12 color-format
- FIR registers used for UV-color-component scaling on OMAP4
- Accumulator registers used for UV-color-component scaling
Add these new registers to save/restore and DUMPREG functions.
Also add two new features for OMAP4:
- FEAT_HANDLE_UV_SEPARATE - this is used on OMAP4 as UV color-component requires
separate handling.
- FEAT_ATTR2 - this is used on OMAP4 to configure new ATTRIBUTES2 register.

FIR values can never be zero as per TRM, and the current code writes zero
when scaling is not used. It was not causing any problem as scaling was
disabled when zero was written. Its still safer to not write zero to
it in any case.
Now we configure correct FIR values even when scaling is not used (i.e. set FIR
to 1024 when scaling is not used), but the scaling enable bits are still kept
off if the scaling is not needed.

Commit e66eed651fd1 ("list: remove prefetching from regular list
iterators") removed the include of prefetch.h from list.h, which
uncovered several cases that had apparently relied on that rather
obscure header file dependency.
So this fixes things up a bit, using
grep -L linux/prefetch.h $(git grep -l '[^a-z_]prefetchw*(' -- '*.[ch]')
grep -L 'prefetchw*(' $(git grep -l 'linux/prefetch.h' -- '*.[ch]')
to guide us in finding files that either need <linux/prefetch.h>
inclusion, or have it despite not needing it.
There are more of them around (mostly network drivers), but this gets
many core ones.

(software mode). A DSS feature is used to indicate the HDMI

the HDMI IP calculates the CTS parameter for audio clock

computation of the CTS parameter by the HDMI IP (hardware mode).
The rest of the revisions require the HDMI driver to perform the

In the previous DSI driver design, a private workqueue was needed to prevent a
deadlock as explained in the commit : 0f16aa0ae6b84d7ae72fbe8999e6a94cb78edd4e
. In the current design, the workqueue is only used for queueing delayed work in
the case where we don't get a FRAMEDONE interrupt for 250 milliseconds. It is
safe to remove the private workqueue amd use the system workqueue instead to
schedule the delayed work with the new design where the deadlock can't occur.

This moves the

return -ENXIO;
check _AFTER_ the call to do_remove_conflicting_framebuffers() as this
would (now in a safe way) allow a native driver to replace the
conflicting one even if all slots in registered_fb[] are taken.
This also prevents unregistering a framebuffer that is no longer
registered (vga16f will unregister at module unload time even if the
frame buffer had been unregistered earlier due to being found
conflicting).

When a register_framebuffer() call results in us removing old
conflicting framebuffers, the new registration_lock doesn't protect that
situation. And we can't just add the same locking to the function,
because these functions call each other: register_framebuffer() calls
remove_conflicting_framebuffers, which in turn calls
unregister_framebuffer for any conflicting entry.
In order to fix it, this just creates wrapper functions around all three
functions and makes the versions that actually do the work be called
"do_xxx()", leaving just the wrapper that gets the lock and calls the
worker function.
So the rule becomes simply that "do_xxxx()" has to be called with the
lock held, and now do_register_framebuffer() can just call
do_remove_conflicting_framebuffers(), and that in turn can call
_do_unregister_framebuffer(), and there is no deadlock, and we can hold
the registration lock over the whole sequence, fixing the races.
It also makes error cases simpler, and fixes one situation where we
would return from unregister_framebuffer() without releasing the lock,
pointed out by Bruno Prémont.
