+ * struct tps65010_board - packages GPIO and LED lines
+ * @base: the GPIO number to assign to GPIO-1
+ * @outmask: bit (N-1) is set to allow GPIO-N to be used as an
+ *     (open drain) output
+ * @setup: optional callback issued once the GPIOs are valid
+ * @teardown: optional callback issued before the GPIOs are invalidated
+ * @context: optional parameter passed to setup() and teardown()
+ *
+ * Board data may be used to package the GPIO (and LED) lines for use
+ * in by the generic GPIO and LED frameworks.  The first four GPIOs
+ * starting at gpio_base are GPIO1..GPIO4.  The next two are LED1/nPG
+ * and LED2 (with hardware blinking capability, not currently exposed).
+ *
+ * The @setup callback may be used with the kind of board-specific glue
+ * which hands the (now-valid) GPIOs to other drivers, or which puts
+ * devices in their initial states using these GPIOs.
