+ * Copyright (C) 2007  Paul Mundt
+ *
+ * Most SH reference boards include a number of individual LEDs that can
+ * be independently controlled (either via a pre-defined hardware
+ * function or via the LED class, if desired -- the hardware tends to
+ * encapsulate some of the same "triggers" that the LED class supports,
+ * so there's not too much value in it).
+ *
+ * Additionally, most of these boards also have a LED bank that we've
+ * traditionally used for strobing the load average. This use case is
+ * handled by this driver, rather than giving each LED bit position its
+ * own struct device.
