Maxim Levitsky 4651918a4a [media] IR: extend ir_raw_event and do refactoring
Add new event types for timeout & carrier report
Move timeout handling from ir_raw_event_store_with_filter to
ir-lirc-codec, where it is really needed.
Now lirc bridge ensures proper gap handling.
Extend lirc bridge for carrier & timeout reports

Note: all new ir_raw_event variables now should be initialized
like that: DEFINE_IR_RAW_EVENT(ev);

To clean an existing event, use init_ir_raw_event(&ev);

Jarod Wilson 4e6e29ad10 [media] IR/nuvoton: address all checkpatch.pl issues
The driver was missing KERN_ facilities on a number of printks. The
register dump functions have been updated to use KERN_INFO, so that the
register dump gets logged in syslog (they only run on driver load, and
only when debug is enabled). The buffer dump routine now uses
KERN_DEBUG, as that spew will happen quite frequently (several times
every IR signal), and shouldn't need to be logged.

Also split up the small handful of lines that were just over 80
characaters, and fixed the ioctl.h include.

Jarod Wilson fbdc781c6b [media] nuvoton-cir: add proper rx fifo overrun handling
Per discussion with Andy Walls on irc, rx fifo overruns are not all that
uncommon on a busy system, and the initial posting of the nuvoton-cir
driver doesn't handle them well enough. With this addition, we'll drain
the hw fifo, attempt to process any ir pulse trains completed with that
flush, then we'll issue a hw rx fifo clear and reset the raw ir sample
kfifo and start over collecting raw ir data.

Also slightly refactors the cir interrupt enabling so that we always get
consistent flags set and only have to modify them in one place, should
they need to be altered.

Jarod Wilson 6d2f5c2788 [media] IR: add driver for Nuvoton w836x7hg integrated CIR
This is a new ir-core pnp driver for the Nuvoton w836x7hg integrated CIR
function. The chip is found on at least the ASRock ION 330HT boxes and
apparently, on a number of Intel DP55-series motherboards:

http://www.asrock.com/nettop/overview.asp?Model=ION%20330HT
http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=17685&lang=eng

This driver was made possible by a hardware donation from Nuvoton, along
with sample code (in the form of an lirc driver) and datasheet, so huge
thanks to them for supporting this effort. Note that this driver
constitutes a massive rewrite, porting from the lirc interfaces to the
ir-core interfaces, and restructuring the driver to look more like Maxim
Levitsky's ene_ir driver (as well as generally making it look more like
kernel code).

There's some work left to be done on this driver, to fully support the
range of functionality possible, but receive and IR power-on/wake are
both functional (may require setting wake key under another OS atm). The
hardware I've got (one of the ASRock boxes) only supports RX, so TX is
completely untested as of yet. Certain RX parameters, like sample
resolution and RX IRQ sample length trigger level could possibly stand
to be made tweakable via modparams or sysfs nodes, but the current
values work well enough for me w/an MCE RC6A remote.

The original lirc driver carried support for the Windows MCE IR
keyboard/mouse device, which I plan to add back generically, in a way
that should be usable by any raw IR receiver (or at least by this driver
and the mceusb driver).

Suspend and resume have also been tested, the power button on my remote
can be used to wake the machine, and CIR functionality resumes just
fine. Module unload/reload has also been tested, though not extensively
or repetitively. Also tested to work with the lirc bridge plugin for
userspace decoding.
