This reverts commit
bc52d6eb44de8f19934768d4d10d19fdbdc99950.
On newer kernels, a saa7134 board stopped to display TV video output
properly. After a bisect, I found it as the commit causing the issue.
Turns out that v4l_bound_align_image isn't doing the same bounding
calculation as manually done previously in saa7134_try_fmt_vid_cap.
What isn't equal is the calculation done in clamp align, while
previously it did "f->fmt.pix.width &= ~0x03", clamp_align function
does "Round to nearest aligned value" as stated in the comment, which
yields a different result. If I comment the round calculation in
clamp_align like this: "x = (x /*+ (1 << (align - 1))*/) & mask",
I get it fixed too, because this way the calculation is the same then.

Better to move those functions to an internal header, for some reasons:
1) Header will be a little more cleaner;
2) It avoids the need of recompile everything (bridge/hardware drivers, etc),
just because a new decoder were added, or some other internal change were needed;
3) Better organize the ir-core API, splitting the functions that are internal to

drivers/media/IR/ir-raw-event.c is currently written with the assumption
that all "raw" hardware will generate events only on state change (i.e.
when a pulse or space starts).
However, some hardware (like mceusb, probably the most popular IR receiver
out there) only generates duration data (and that data is buffered so using
any kind of timing on the data is futile).
Furthermore, using signed int's to represent pulse/space durations is a
well-known approach when writing ir decoders.
With this patch:
- s64 int's are used to represent pulse/space durations in ns
- a workqueue is used to decode the ir protocols outside of interrupt context
- #defines are added to make decoders clearer
- decoder reset is implemented by passing a zero duration to the kfifo queue
and decoders are updated accordingly

V4L/DVB: ir-nec-decoder: Reimplement the entire decoder
Thanks to Andy Walls <awalls@md.metrocast.net> for pointing me his
code, that gave me some ideas to better implement it.
After some work with saa7134 bits, I found a way to catch both IRQ
edge pulses. By enabling it, the NEC decoder can now take both
pulse and spaces into account, making it more precise.
Instead of the old strategy of handling the events all at once,
this code implements a state machine. Due to that, it handles
individual pulse or space events, validating them against the
protocol, producing a much more reliable decoding.
With the new implementation, the protocol trailer bits are properly
handled, making possible for the repeat key to work.
Also, the code is now capable of handling both NEC and NEC extended
IR devices. With NEC, it produces a 16 bits code, while with NEC
extended, a 24 bits code is returned.

In addition, I've changed the API slightly so that ir_input_dev is

ir_input_dev the main interface from a driver POV and obscure away

The attached patch rewrites much of the keytable code in

The scancodes are now inserted into the array in sorted

The code has also been shrunk by about 150 lines.
In addition it fixes the following bugs:
Any use of ir_seek_table() was racy.
ir_dev->driver_name is leaked between ir_input_register() and
ir_input_unregister().
ir_setkeycode() unconditionally does clear_bit() on dev->keybit
when removing a mapping, but there might be another mapping with
a different scancode and the same keycode.

V4L/DVB: saa7134: Add support for both positive and negative edge IRQ
The code that enables IRQ for the Remote Controller on saa7134 is a little
messy: it is outside saa7134-input, it checks if RC is GPIO based, and
it mixes both serial raw decode with parallel reads from a hardware-based
IR decoder.
Also, currently, it doesn't allow to trigger both transition edges at GPIO16
and GPIO18 lines. A rework on the code is needed to provide a better way
to specify what saa7134-input needs, maybe even moving part of the code from
saa7134-core and saa7134-cards into saa7134-input.
Yet, as a large rework is happening at RC core, it is better to wait until
the core changes stablize, in order to rework saa7134 RC internals.While
this don't happen, let's just change the logic a little bit to allow
enabling IRQ to be generated on both edge transitions, in order to better

V4L/DVB: Break Remote Controller keymaps into modules
The original Remote Controller approach were very messy: a big file,
that were part of ir-common kernel module, containing 64 different
RC keymap tables, used by the V4L/DVB drivers.
Better to break each RC keymap table into a separate module,
registering them into rc core on a process similar to the fs/nls tables.
As an userspace program is now in charge of loading those tables,
adds an option to allow the complete removal of those tables from
kernelspace.
Yet, on embedded devices like Set Top Boxes and TV sets, maybe the
only available input device is the IR. So, we should keep allowing
the usage of in-kernel tables, but a latter patch should change
the default to 'n', after giving some time for distros to add
