This is the README using the ITE IT8705 and IT8712 CIR port for LIRC.
The IT8705 for example can be found on the ECS K7S5A.
The driver supports receiving (MODE2) and sending (PULSE). It seems
sending 'LIRC_CAN_SEND_PULSE' isn't optimal for this type of hardware.
But because I don't know how to implement 'LIRC_CAN_SEND_CODE', I did
it this way.
Attention:
Because of missing hardware, the following hasn't been tested:
a) receiving with demodulator enabled,
b) sending (debugging output looks good) and
c) using IT8712
Any help and/or additions etc. is welcome.
lirc_it87 knows about the following module-parameters:
MODULE_DESCRIPTION("LIRC driver for ITE IT8712/IT8705 CIR port");
MODULE_PARM(io, "i");
MODULE_PARM_DESC(io, "I/O base address (default: 0x310)");
MODULE_PARM(irq, "i");
MODULE_PARM_DESC(irq, "Interrupt (1,3-12) (default: 7)");
MODULE_PARM(it87_enable_demodulator, "i");
MODULE_PARM_DESC(it87_enable_demodulator, "Receiver demodulator
enable/disable (1/0), default: 0");
Usage:
a) io and irq:
If the driver finds the IT8705/12-CIR port initialized, io and irq of
the preinitialized hardware is used by the driver. If both values are
read 0x0 from the hardware, the default or given value is used.
Note: I experienced using irq=3. The driver initialized without any
problems, but no irqs are recognized by the system. I had to switch
back to default, irq 7.
b) it87_enable_demodulator:
The demodulator for the receiver can be switched off (default within
the driver). If you need the demodulator simple enable it by the
following way: it87_enable_demodulator=1.

Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
