May be you can use udev In the
err = request_threaded_irq(pdata->irq, NULL, receive_thread,
pdata->irqflags, "interrupt", ir);
In reciever thread
static irqreturn_t receive_threar(int irq, void *context_data)
{
struct data *dh = context_data;
input_report_key(dh->input_dev, key, 1);
input_sync(dh>input_dev)
}
In userspace use evetest like application to wait on the event or simple
select on /dev/input should work
