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.
