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.

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%20330HThttp://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.

XU control information is supposed to be entirely discoverable using
standard UVC queries. As some devices report bogus information (such as
reporting a read-only control as being read-write), add a fixup table
for XU controls.
This table can also be used to selectively disable requests supposed to
be supported by all XU controls (GET_MIN, GET_MAX, GET_DEF, GET_RES) but
not correctly (or at all) supported by the device.
The table currently disables GET_CUR on the Logitech motor control XU
pan/tilt controls.

This patch removes the sysadmin requirements for UVCIOC_CTRL_MAP (and the stub
implementation of UVCIOC_CTRL_ADD). This requirement no longer makes sense with
the new XU control access mechanisms since XU controls can be accessed without
adding control mappings first.
A maximum number (currently 1024) of control mappings per device is enforced to
avoid excess memory consumption caused by careless user space applications.

Devices advertise XU controls using a bitmask, in which each bit
corresponds to a control. The control selector, used to query the
control, isn't available in the USB descriptors.
All known UVC devices use control selectors equal to the control bit
index plus one. Hardcode that relationship in the driver, making the
UVCIOC_CTRL_ADD ioctl obsolete. All necessary information about XU
controls can be obtained by the driver at enumeration time.
The UVCIOC_CTRL_ADD ioctl is still supported for compatibility reasons,
but now always returns -EEXIST.
Finally, control mappings are now on a per-device basis and no longer
global.
As this changes the userspace interface, bump the driver version number
to 1.0.0 (it was about time).
