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