+/*
+ * cpld-gpio-bus.c: provides support for the CPLD GPIO bus found on some LaCie
+ * boards (as the 2Big/5Big Network v2 and the 2Big NAS). This parallel GPIO
+ * bus exposes two registers (address and data). Each of this register is made
+ * up of several dedicated GPIOs. An extra GPIO is used to notify the CPLD that
+ * the registers have been updated.
+ *
+ * Mostly this bus is used to configure the LEDs on LaCie boards.
