+ * and an IR receptor used for the remote control.  When any key is
+ * pressed, or its autorepeat kicks in, an event is sent.  This driver
+ * read those events from the small (32 event) queue and reports them.
+ *
+ * Because we communicate with the MSP430 using I2C, and all I2C calls
+ * in Linux sleep, we need to cons up a kind of threaded IRQ handler
+ * using a work_struct.  The IRQ is active low, but we use it through
+ * the GPIO controller so we can trigger on falling edges.
+ *
+ * Note that physically there can only be one of these devices.
+ *
+ * This driver was tested with firmware revision A4.
