+ * - Initial implementation
+ *
+ *
+ * This driver implements the bus-specific part of the i2400m for
+ * SDIO. Check i2400m.h for a generic driver description.
+ *
+ * ARCHITECTURE
+ *
+ * This driver sits under the bus-generic i2400m driver, providing the
+ * connection to the device.
+ *
+ * When probed, all the function pointers are setup and then the
+ * bus-generic code called. The generic driver will then use the
+ * provided pointers for uploading firmware (i2400ms_bus_bm*() in
+ * sdio-fw.c) and then setting up the device (i2400ms_dev_*() in
+ * sdio.c).
+ *
+ * Once firmware is uploaded, TX functions (sdio-tx.c) are called when
+ * data is ready for transmission in the TX fifo; then the SDIO IRQ is
+ * fired and data is available (sdio-rx.c), it is sent to the generic
+ * driver for processing with i2400m_rx.
