Hans Petter Selasky pointed out to me that we're leaking urbs when
mce_async_out is called. Its used both for configuring the hardware and
for transmitting IR data. In the tx case, mce_request_packet actually
allocates both a urb and the transfer buffer, neither of which was being
torn down. Do that in the tx callback.

Aside from the initial "hey, lets make sure we've flushed any
pre-existing data on the device" call to mce_sync_in, every other one of
the calls was entirely superfluous. Ergo, remove them all, and rename
the one and only (questionably) useful one to reflect what it really
does. Verified on both gen2 and gen3 hardware to make zero difference.
Well, except that you no longer get a bunch of urb submit failures from
the unneeded mce_sync_in calls. Oh. And move that flush to a point
*after* we've wired up the inbound urb, or it won't do squat. I have
half a mind to just remove it entirely, but someone thought it was
necessary at some point, and it doesn't seem to hurt, so lets leave it
for the time being.
This excercise took place due to insightful questions asked by Hans
Petter Selasky, about the possible reuse of the inbound urb before it
was actually availble by mce_sync_in, so thanks to him for motivating
this cleanup.

The cx23885 driver was including staging/altera.h, but that file has

Why a non-staging driver was including a staging driver is beyond me,
but this fixes the build so everything is happy for now.
For the record, it's not ok for a non-staging driver to depend on a
staging one, as that implies that the non-staging one should also be in
the staging tree if that's needed.

This is a new driver for the Fintek LPC SuperIO CIR function, in the
Fintek F71809 chip. Hardware and datasheets were provided by Fintek, so
thanks go to them for supporting this effort.
This driver started out as a copy of the nuvoton-cir driver, and was
then modified as needed for the Fintek chip. The two share many
similaries, though the buffer handling for the Fintek chip is actually
nearly identical to the mceusb buffer handling, so the parser routine is
almost a drop-in copy of the mceusb buffer parser (a candidate for being
abstracted out into shared code at some point).
This initial code drop *only* supports receive, but the hardware does
support transmit as well. I really haven't even started to look at
what's required, but my guess is that its also pretty similar to mceusb.
Most people are probably only really interested in RX anyway though, so
I think its good to get this out there even with only RX.
(Nb: there are also Fintek-made mceusb receivers, which presumably, this
chip shares CIR hardware with).
This hardware can be found on at least Jetway NC98 boards and derivative
systems, and likely others as well. Functionality was tested with an
NC98 development board, in-kernel decode of RC6 (mce), RC5 (hauppauge)
and NEC-ish (tivo) remotes all successful, as was lirc userspace decode
of the RC6 remote.

ictx->touch is intialied in imon_init_intf1, to the result of calling the
function that contains this code. Thus, in this code, input_free_device
should be called on touch itself.

This is a new rc-core device driver for the IR transceivers made by
RedRat Ltd. (http://redrat.co.uk/). It started out life as an
out-of-lirc-tree lirc driver, maintained in its own repo on sourceforge,
by Stephen Cox. He started porting it to what was then ir-core, and I
finally picked it up about two week ago and did a fairly large overhaul
on it, and its now into a state where I'm fairly comfortable submitting
it here for review and inclusion in the kernel. I'm claiming authorship
of this driver, since while it started out as Stephen's work, its
definitely a derivative work now, at 876 lines added and 1698 lines
removed since grabbing it from sourceforge. Stephen's name is retained
as secondary author though, and credited in the headers. Those
interested in seeing how the changes evolved can (at least for now) look
at this branch in my git tree:
http://git.kernel.org/?p=linux/kernel/git/jarod/linux-2.6-ir.git;a=shortlog;h=refs/heads/redrat3
That won't be around forever though, and I'm doing this as a single
commit to go into mainline. Anyway...
I've successfully tested in-kernel decode of rc5, rc6 and nec remotes,
as well as lirc userspace decode of rc5 and rc6. There are still some
quirks here to sort out with rc5 lirc userspace decode, but I'm working
with the RedRat folks themselves to figure out what's going on there
(rc5 lirc decode works, but you only get an event on key release --
in-kernel rc5 decode behaves perfectly fine). Note that lirc decode of
rc6 is working perfectly. Transmit is also working, tested by pointing
the redrat3 at an mceusb transceiver, which happily picked up the
transmitted signals and properly decoded them.
There's no default remote for this hardware, so its somewhat arbitrarily
set to use the Hauppauge RC5 keymap by default. Easily changed out by
way of ir-keytable and irrelevant if you're using lircd for decode.

Continuing with IR transmit after resuming from suspend seems fairly
useless, given that the only place we can actually end up suspending is
after IR has been send and we're simply mdelay'ing. Lets simplify the
resume path by just waiting on tx to complete in the suspend path, then
we know we can't be transmitting on resume, and reinitialization of the
hardware registers becomes more straight-forward.

There was some rather odd spacing in a few of the ite8709-specific

a simple reformatting.

Just recently acquired an Asus Eee Box PC with an onboard IR receiver
driven by ite-cir (ITE8713 sub-variant). Works out of the box with the
ite-cir driver in 2.6.39, but stops working after a suspend/resume
cycle. Its fixed by simply reinitializing registers after resume,
similar to what's done in the nuvoton-cir driver. I've not tested with
any other ITE variant, but code inspection suggests this should be safe
on all variants.

- Set a default timeout (matching mceusb.c) and use
ir_raw_event_store_with_filter, which leads to better behavior when
using lirc userspace decoding with this hardware

This camera driver supports only rising edge, which is the default
setting of the device. The function mt9m111_setup_pixfmt() overwrites
this setting. So the driver actually uses falling edge.
This patch corrects that.

The setup of the pixel clock is done wrong in the mt9v022 driver.
The 'Invert Pixel Clock' bit has to be set to 1 for falling edge
and not for rising. This is not clearly described in the data
