+ Say Y here if you want to build support for the VIA VT8231
+ and VIA VT1211 IrDA controllers, found on the motherboards using
+ those those VIA chipsets. To use this controller, you will need
+ to plug a specific 5 pins FIR IrDA dongle in the specific
+ motherboard connector. The driver provides support for SIR, MIR
+ and FIR (4Mbps) speeds.
+
+ You will need to specify the 'dongle_id' module parameter to
+ indicate the FIR dongle attached to the controller.
+
+ If you want to compile it as a module, say M here and read
+ <file:Documentation/modules.txt>. The module will be called
+ via-ircc.
