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.

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.

If an IR command is sent (using the LIRC userspace) to rc-loopback
which doesn't include a trailing space, the result is that the message
won't be completely decoded. In addition, "leftovers" from a previous

Thanks to some excellent investigative work by Douglas Clowes, it was
uncovered that the older w83667hg Nuvoton chip functions with this
driver after actually enabling the CIR function via its multi-function
chip config register. The CIR and CIR wide-band sensor enable bits are
just in a different place on this hardware, so we only poke register
0x27 on 677 hardware now, and we poke register 0x2c on the 667 now.

There are additional chip IDs that report a PNP ID of NTN0530, which we
were refusing to load on. Instead, lets just warn if we encounter an
unknown chip, as there's a chance it will work just fine.
Also, expand the list of known hardware to include both an earlier and a
later generation chip that this driver should function with. Douglas has
an older w83667hg variant, that with a touch more work, will be
supported by this driver, and Lutz has a newer w83677hg variant that
works without any further modifications to the driver.

The imon_ir_change_protocol function gets called two different ways, one
way is from rc_register_device, for initial protocol selection/setup,
and the other is via a userspace-initiated protocol change request,
either by direct sysfs prodding or by something like ir-keytable.
In the rc_register_device case, the imon context lock is already held,
but when initiated from userspace, it is not, so we must acquire it,
prior to calling send_packet, which requires that the lock is held.
Without this change, there's an easily reproduceable deadlock when
another function calls send_packet (such as either of the display write
fops) after a userspace-initiated change_protocol.
With a lock-debugging-enabled kernel, I was getting this:

The Apple and TiVo remotes I've got use an NEC-ish protocol, but rather
than a command/not_command pair, they have what appear to be vendor ID
bytes. This change makes the NEC decoder warn if the command/not_command
checksum fails, but then passes along a full 32-bit scancode for keymap
lookup. This change should make no difference for existing keymaps,
since they simply won't have 32-bit scancodes, but allows for a 32-bit
keymap. At the moment, that'll have to be uploaded by the user, but I've
got Apple and TiVo remote keymaps forthcoming.
In the long run (2.6.40, hopefully), we should probably just always use
all 32 bits for all NEC keymaps, but this should get us by for 2.6.39.
(Note that a few of the TiVo keys actuallly *do* pass the command
checksum, so for now, the keymap for this remote will have to be a mix
of 24-bit and 32-bit scancodes, but so be it).

This keymap were used for the Hauppauge Black remote controller
only. It also contains some keycodes not found there. As the
Hauppauge Black is now part of the hauppauge keymap, just remove
it.
Also, remove the modprobe hacks to select between the Gray
and the Black versions of the remote controller as:
- Both are supported by default by the keymap;
- If the user just wants one keyboard supported,
it is just a matter of changing the keymap via
the userspace tool (ir-keytable), removing
the keys that he doesn't desire. As ir-keytable
auto-loads the keys via udev, this is better than
obscure modprobe parameters.

The rc-hauppauge-new map is a messy thing, as it bundles 3
different remote controllers as if they were just one,
discarding the address byte. Also, some key maps are wrong.
With the conversion to the new rc-core, it is likely that
most of the devices won't be working properly, as the i2c
driver and the raw decoders are now providing 16 bits for
the remote, instead of just 8.

This patch solves half of the problem by renaming the

This is a second version of an rc-core based driver for the ITE Tech IT8712F
CIR and now for a pair of other variants of the IT8512 CIR too.
This driver should replace the lirc_it87 and lirc_ite8709 currently living in
the LIRC staging directory.
The driver should support the ITE8704, ITE8713, ITE8708 and ITE8709 (this last
one yet untested) PNP ID's.
The code doesn'te reuse code from the pre-existing LIRC drivers, but has been
written from scratch using the nuvoton.cir driver as a skeleton.
This new driver shouldn't exhibit timing problems when running under load (or
with interrupts disabled for relatively long times). It works OOTB with the
RC6 MCE remote bundled with the ASUS EEEBox. TX support is implemented, but
I'm unable to test it since my hardware lacks TX capability.

There's a Realtek combo card reader and IR receiver device with multiple
usb interfaces on it. The mceusb driver is incorrectly grabbing all of
them. This change should make it bind to only interface 2 (patch based
on lsusb output on the linux-media list from Lucian Muresan).
Tested regression-free with the six mceusb devices I have myself.

The CIR Wake FIFO is 67 bytes long, but the stock remote appears to only
populate 65 of them. Limit comparison to 65 bytes, and wake from suspend
works a whole lot better (it wasn't working at all for most folks).
Fix based on comparison with the old lirc_wb677 driver from Nuvoton,
debugging and testing done by Dave Treacy by way of the lirc mailing
list.

With the current matching rules the lookup for rc protocol named rc-5-sz matches with "rc-5" before finding "rc-5-sz". Thus one is able to never enable/disable the rc-5-sz protocol via sysfs.
Fix the lookup to require an exact match which allows the manipulation of sz protocol.

The streamzap driver has relatively low sampling resolution, and any
delays in reporting events seem to cause some minor problems for the
likes of irw when using the lirc bridge driver, resulting in a single
keypress registering as multiple independent ones, rather than as a
single press with repeats. If we call ir_raw_event_handle() more
frequently and reset the rawir kfifo at end-of-signal, the behavior
improves quite a bit.

Fixes an egregious bug in mceusb driver, where the receiver was being
put into idle mode far sooner than it should have, thanks to storing a
timeout value that in us where it should be ns. Basically, the receiver
kept going into idle mode before a trailing space had been fully
received, which was causing problems for some protocols, most notably
manifesting as lirc userspace never receiving a trailing space for any
rc5 signals.

My initial thinking was that we should default to mouse mode, so people
could use the mouse function to click on something on a login screen,
but a lot of systems where a remote is useful automatically log in a
user and launch a media center application, some of which hide the
mouse, which can be confusing to users if they punch buttons on the
remote and don't see any feedback. Plus, first and foremost, its a
remote, so lets default to being a remote, and only toggle into mouse
mode when the user explicitly asks for it. As a nice side-effect, this
actually simplifies some of the code a fair bit...

The ene_ir driver was using a private define of MS_TO_NS, which is meant
to be microseconds to nanoseconds. The mceusb driver copied it,
intending to use is a milliseconds to microseconds. Lets move the
defines to a common location, expand and standardize them a touch, so
that we now have:
MS_TO_NS - milliseconds to nanoseconds
MS_TO_US - milliseconds to microseconds
US_TO_NS - microseconds to nanoseconds

Fixing the problem with NEC protocol and repeating keys under the following
circumstances. The problem occurs when there is a repeat code without
properly decoded scancode. This leads to repeat the wrong (last decoded)
scancode.
An example from real life:
I am pressing volume down, then several minutes later i am pressing
volume up, but the real scancode is wrongly decoded and only a repeat
event is emitted, so as a result volume is going down while i am holding
volume up button.
The patch fixes above problem using rc_keyup timeout (as pointed by Mauro).
It just prevents key repeats if they appear after rc_keyup.

This patch adds a loopback driver to rc-core which I've found useful for
running scripted tests of different parts of rc-core without having to
fiddle with real hardware.
Basically it emulates hardware with a learning and a non-learning
receiver and two transmitters (which correspond to the two
receivers). TX data that is sent is fed back as input on the
corresponding receiver, which allows for debugging of IR decoders,
keymaps, etc.

When trying to create persistent device names for mceusb and streamzap
devices, I noticed that their respective drivers are not creating the rc
device as a child of the USB device. Rather it creates it as virtual
device. As a result, udev cannot use the USB device information to
create persistent device names for event and lirc devices associated
with the rc device. Not having persistent device names makes it more
difficult to make use of the devices in userspace as their names can
change.
Forward-ported to media_tree staging/for_v2.6.38 and tested with
both streamzap and mceusb devices:
$ ll /dev/input/by-id/
...
lrwxrwxrwx. 1 root root 9 Nov 17 17:06 usb-Streamzap__Inc._Streamzap_Remote_Control-event-if00 -> ../event6

The Remote Controller subsystem is meant to be used not only by Infra Red
but also for similar types of Remote Controllers. The core is not specific
to Infra Red. As such, rename:
- ir-core.h to rc-core.h
- IR_CORE to RC_CORE
- namespace inside rc-core.c/rc-core.h
To be consistent with the other changes.

This patch merges the ir_input_dev and ir_dev_props structs into a single
struct called rc_dev. The drivers and various functions in rc-core used
by the drivers are also changed to use rc_dev as the primary interface
when dealing with rc-core.
This means that the input_dev is abstracted away from the drivers which
is necessary if we ever want to support multiple input devs per rc device.
The new API is similar to what the input subsystem uses, i.e:
rc_device_alloc()
rc_device_free()
rc_device_register()
rc_device_unregister()
