|
|
|
+ * - 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.
