On certain platforms such as DRA7, SPIs 0, 1, 2, 3, 5, 6, 10, 131,
132, 133 are direct wired to hardware blocks bypassing crossbar.
This quirky implementation is *NOT* supposed to be the expectation
of crossbar hardware usage. However, these are already marked in our
description of the hardware with SKIP and RESERVED where appropriate.
Unfortunately, we need to be able to refer to these hardwired IRQs.
So, to request these, crossbar driver can use the existing information
from it's table that these SKIP/RESERVED maps are direct wired sources
and generic allocation/programming of crossbar should be avoided.

The current crossbar description does not include the description
required for the consumer of the crossbar, a.k.a devices whoes events
pass through the crossbar into the GIC interrupt controller.
So, provide documentation for the same.

crossbar mapping
Currently we attempt to map any crossbar value to an IRQ, however,
this is not correct from hardware perspective. There is a max crossbar
event number upto which hardware supports. So describe the same in
device tree using 'ti,max-crossbar-sources' property and use it to
validate requests.
[ jac - remove MAX_SOURCES from binding doc, use integer because we
shouldn't put implementation details in the binding docs ]

Since crossbar is s/w configurable, the initial settings of the
crossbar cannot be assumed to be sane. This implies that:
a) On initialization all un-reserved crossbars must be initialized to
a known 'safe' value.
b) When unmapping the interrupt, the safe value must be written to
ensure that the crossbar mapping matches with interrupt controller
usage.
So provide a safe value in the dt data to map if
'0' is not safe for the platform and use it during init and unmap
While at this, fix the below checkpatch warning.

When, in the system due to varied reasons, interrupts might be unusable
due to hardware behavior, but register maps do exist, then those interrupts
should be skipped while mapping irq to crossbars.

In addition to consolidating the or1k-pic with other interrupt
controllers, this makes OpenRISC less tied to its on-cpu
interrupt controller.
All or1k-pic specific parts are moved out of irq.c and into
drivers/irqchip/irq-or1k-pic.c
In that transition, the functionality have been divided into
three chip variants.
One that handles level triggered interrupts, one that handles edge
triggered interrupts and one that handles the interrupt
controller that is present in the or1200 OpenRISC cpu
implementation.

to be added at the standard RC5 decoder
- added decoder for the XMP IR protocol
- tuner driver moved from staging into mainstream: msi3101 (renamed as

V4L2_CID_BASE_LASTP1 should be V4L2_CID_LASTP1. This has probably been wrong
since the earliest days of this documentation until I did a copy-and-paste
and found out that V4L2_CID_BASE_LASTP1 doesn't actually exist :-)

The fact that the pixelformat is using a packed RGB format has nothing
to do with the colorspace that is being used. Those are very different
things. The colorspace decides what color a triplet of RGB numbers
actually map to. E.g. a red color with values (255, 0, 0) is a different
type of red depending on the colorspace. If the original pixelformat was
e.g. YUV in colorspace REC709, then after the conversion to RGB the
colorspace is still REC709. Unless the hardware actually converted the
colorspace as well from REC709 to sRGB, but that rarely if ever happens.
Remove this incorrect comment.

The v4l2_pix_format structure has no reserved field. It is embedded in
the v4l2_framebuffer structure which has no reserved fields either, and
in the v4l2_format structure which has reserved fields that were not
previously required to be zeroed out by applications.
To allow extending v4l2_pix_format, inline it in the v4l2_framebuffer
structure, and use the priv field as a magic value to indicate that the
application has set all v4l2_pix_format extended fields and zeroed all
reserved fields following the v4l2_pix_format field in the v4l2_format
structure.
The availability of this API extension is reported to userspace through
the new V4L2_CAP_EXT_PIX_FORMAT capability flag. Just checking that the
priv field is still set to the magic value at [GS]_FMT return wouldn't
be enough, as older kernels don't zero the priv field on return.
To simplify the internal API towards drivers zero the extended fields
and set the priv field to the magic value for applications not aware of
the extensions.
