Find EVIOCGID in drivers/input/evdev.c
Will use same value as sunxi-cir.c & gpio-ir-recv.c, if these value has 
no special requirement.
         rcdev->input_id.bustype = BUS_HOST;
         rcdev->input_id.vendor = 0x0001;
         rcdev->input_id.product = 0x0001;
         rcdev->input_id.version = 0x0100;

Do you mean kernel decoder is enough to cover?
We use user space lircd to cosider more flexibility, even some 
non-standard protocol.

Anyway both method can be supported, depending on whether setting the 
optional property "linux,rc-map-name" or not.

Thanks
