|
||||
* - 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.
