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
the v4l-utils with the ir-keytable program, to allow the table
load via userspace.

Instead of having all RC tables hardcoded on one file with
all tables there, add infrastructure for registering and dynamically
load the table(s) when needed.

The usage of macros ensures that the proper namespace is being used
by all tables. It also makes easier to associate a keytable with
the name used inside the drivers.

Several DVB drivers use a different name convention. As we're moving

It seems impossible for ov to be NULL at this point.
The semantic match that finds the problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>

statement S1,S3;
iterator iter;
@@
if ((E == NULL && ...) || ...)
{
... when != false ((E == NULL && ...) || ...)
when != true ((E != NULL && ...) || ...)
when != iter(E,...) S1
when != E = E1
(
sizeof(E->f)
|
* E->f
)
... when any
return ...;
}
else S3
// </smpl>

Especially when IR needs to do polling, it generates lots of wakeups per
second. This makes no sense, if the input event device is closed.
Adds a callback handler to the IR hardware driver, to allow registering
an open/close ops.

IR is an alias for Infrared Remote, while RC is an alias for Remote
Controller.
While currently all implementations are with Infrared Remote Controller,
this subsystem is not meant to be used only by IR type of RC's. So,
as discussed on both linux-media and linux-input, the better is to
rename the subsystem as Remote Controller.
While, currently, the only application that uses the /sys/class/irrcv is
ir-keytable application, and its sysfs support works only with the
current linux-next code, it is still possible to change the userspace API
without the risk of breaking applications. So, better to rename this
sooner than later.
Later patches will be needed to rename the files and to move them away
from drivers/media, but this is not a critical issue. So, for now,
let's just change the name of the sysfs class/nodes.

Some decoders and a lirc_dev interface may need some other operations to work.
For example: IR device register/unregister and ir_keydown events may need to
be tracked.
As some operations can occur in interrupt time, and a lock is needed to prevent
un-registering a decode while decoding a key, the lock needed to be convert
into a spin lock.

Instead of hardcoding the protocols into ir-core, add a register interface
for the IR protocol decoders, and convert ir-nec-decoder into a client of
ir-core.
With this approach, it is possible to dynamically load the needed IR protocols,
and to add a RAW IR interface module, registered as one IR raw protocol decoder.
This patch opens a way to register a lirc_dev interface to work as an userspace
IR protocol decoder.

At raw_decode mode, the key is processed after the end of a timer. The
previous code resets the timer every time something is received at the IR
port. While this works fine with IR's that don't implement repeat, like
Avermedia RM-JX IR, it keeps waiting until keydown, on IR's that implement
NEC repeat command, like the Terratec yellow.
The solution is to change the behaviour to do the timeout after the first
received data.
The timeout is currently set to 15 ms, as it works fine with NEC protcocol.
It may need some adjustments to support other protocols and to better handle
spurious detections that may happen with some IR sensors.

Adds a method to pass IR raw pulse/code events into ir-core. This is
needed in order to support LIRC. It also helps to move common code
from the drivers into the core.
In order to allow testing, it implements a simple NEC protocol decoder
at ir-nec-decoder.c file. The logic is about the same used at saa7134
driver that handles Avermedia M135A and Encore FM53 boards.

signal properly
For the sequence streamon -> streamoff and again s_input, it fails
to lock the signal, since streamoff puts TVP514x into power off state
which leads to failure in sub-sequent s_input.
So add powerup sequence in s_routing (if disabled), since it is
important to lock the signal at this stage.
