Laurent Pinchart bddb9d0e97 [media] uvcvideo: Support allocating buffers larger than the current frame size
The queue_setup handler takes an optional format argument that can be
used to allocate buffers for a format different than the current format.
The uvcvideo driver doesn't support changing the format when buffers
have been allocated, but there's no reason not to support allocating
buffers larger than the minimum size.

When the format argument isn't NULL verify that the requested image size
is large enough for the current format and use it for the buffer size.

Hans Verkuil efab6b6a6e [media] vivi: queue_setup improvements
Drop the vid_limit module option: there is really no need to limit this.
No other driver does that. If you try to allocate more buffers then vb2
will automatically reduce the number of buffers anyway.

Also add sanity checks if the size in the fmt argument is going to be
used and drop the code that checks against *nbuffers == 0: this can
never happen (the vb2 framework ensures that) and the code was wrong
anyway since *nbuffers should have been set to the minimum number of
required buffers which is 1 for this driver.

Since vivi is often used as a template driver it is good to have this
driver be as compliant as possible. This broken code was for example
copied to the s2255 driver (which is being fixed as well).

The sequence counting was not reset to 0 between each streaming run,
and it was increased only every other frame. This is incorrect behavior:
the confusion is with FIELD_ALTERNATE systems where each field is transmitted

Hans Verkuil ab58a30162 [media] v4l2-subdev: Allow 32-bit compat ioctls
Add support for 32-bit ioctls with v4l-subdev device nodes.

Rather than keep adding new ioctls to the list in v4l2-compat-ioctl32.c, just check
if the ioctl is a non-private V4L2 ioctl and if so, call the conversion code.

We keep forgetting to add new ioctls, so this is a more robust solution.

In addition extend the subdev API with support for a compat32 function to
convert custom v4l-subdev ioctls.

Adds a missing section to describe the remote controller interface.

The DocBook is just addin the same documentation as written at
Documentation/ABI/testing/sysfs-class-rc, using the DocBook's
way, and dropping timestamps/contact info.

While that means that we'll have the same info on two parts, there
are parts of the remote controller interface that doesn't belong
at Documentation/ABI/, and it makes sense to have everything
on the same place. This also means that we'll need to manually
track to be sure that both places will be synchronized, but, as
it is not expected much changes on it, this sync can be done
manually.

It also adds an introduction that states that the IR is a normal
evdev/input interface, plus the sysfs class nodes.

Mauro Carvalho Chehab 90f745cea2 [media] DocBook/media_api: Better organize the DocBook
All chapters/parts but Remote controllers have the revision
tags inside the body. Move those to remote_controllers.xml and
do some cleanup.

No functional changes.

James Hogan 18bc174481 [media] media: rc: change 32bit NEC scancode format
Change 32bit NEC scancode format (used by Apple and TiVo remotes) to
encode the data with the correct bit order. Previously the raw bits were
used without being bit reversed, now each 16bit half is bit reversed
compared to before.

So for the raw NEC data:
  (LSB/First) 0xAAaaCCcc (MSB/Last)
(where traditionally AA=address, aa=~address, CC=command, cc=~command)

We now generate the scancodes:
  (MSB) 0x0000AACC (LSB) (normal NEC)
  (MSB) 0x00AAaaCC (LSB) (extended NEC, address check wrong)
  (MSB) 0xaaAAccCC (LSB) (32-bit NEC, command check wrong)

Note that the address byte order in 32-bit NEC scancodes is different to
that of the extended NEC scancodes. I chose this way as it maintains the
order of the bits in the address/command fields, and CC is clearly
intended to be the LSB of the command if the TiVo codes are anything to
go by so it makes sense for AA to also be the LSB.

The TiVo keymap is updated accordingly.

James Hogan 00942d1a1b [media] media: rc: add sysfs scancode filtering interface
Add and document a generic sysfs based scancode filtering interface for
making use of IR data matching hardware to filter out uninteresting
scancodes. Two filters exist, one for normal operation and one for
filtering scancodes which are permitted to wake the system from suspend.

The following files are added to /sys/class/rc/rc?/:
 - filter: normal scancode filter value
 - filter_mask: normal scancode filter mask
 - wakeup_filter: wakeup scancode filter value
 - wakeup_filter_mask: wakeup scancode filter mask

A new s_filter() driver callback is added which must arrange for the
specified filter to be applied at the right time. Drivers can convert
the scancode filter into a raw IR data filter, which can be applied
immediately or later (for wake up filters).
