From: "John W. Linville" <[email protected]>
SDIO support in this driver was intended to support the iwmc3200
device. This hardware never became available to normal humans.
Leaving this driver imposes unwelcome maintenance costs for no clear
benefit.

If there are no objections, I'll push this series through the
wireless-next tree along with the iwmc3200wifi removal.

- * 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.

- * THE PROCEDURE
- *
- * See fw.c for the generic description of this procedure.
- *
- * This file implements only the SDIO specifics. It boils down to how
- * to send a command and waiting for an acknowledgement from the
- * device.
- *
- * All this code is sequential -- all i2400ms_bus_bm_*() functions are
- * executed in the same thread, except i2400ms_bm_irq() [on its own by
- * the SDIO driver]. This makes it possible to avoid locking.
- *
- * COMMAND EXECUTION
- *
- * The generic firmware upload code will call i2400m_bus_bm_cmd_send()
- * to send commands.
- *
- * The SDIO devices expects things in 256 byte blocks, so it will pad
- * it, compute the checksum (if needed) and pass it to SDIO.
- *
- * ACK RECEPTION
- *
- * This works in IRQ mode -- the fw loader says when to wait for data
- * and for that it calls i2400ms_bus_bm_wait_for_ack().
- *
- * This checks if there is any data available (RX size > 0); if not,
- * waits for the IRQ handler to notify about it. Once there is data,
- * it is read and passed to the caller. Doing it this way we don't
- * need much coordination/locking, and it makes it much more difficult
- * for an interrupt to be lost and the wait_for_ack() function getting
- * stuck even when data is pending.
