2010-01-21spi/dw_spi: conditional transfer mode changesGeorge Shore1-0/+16
This allows the switching between transfer modes between 'transmit only', 'receive only' and 'transmit and receive' modes. Due to the design of the SPI block, changing transfer modes requires that the block be disabled; in doing so the chipselect line is inherently deasserted and (usually) the attached device discards its state. Consequentially, switching modes requires that a platform-specific chipselect function has been defined so that the chipselect is not dropped during the change.

2010-01-21spi/dw_spi: remove conditional from 'poll_transfer'.George Shore1-5/+2
The 'poll_transfer' function employs a conditional to test whether the transmit buffer is valid; in doing so, on a receive operation no data is clocked out, thus no data is clocked in and ultimately errors appear. This removes the conditional as the transmit function will be set to a null writer when the transmit buffer is invalid, allowing the driver to clock 0x00 out to the device to receive data from the device.

2010-01-20spi: xilinx_spi: Fix up I/O routine wrapping bogosity.Paul Mundt1-4/+24
xilinx_spi presently makes some fairly questionable assumptions about I/O routines, and attempts to assign ioread32/iowrite32 and friends directly to its own internal function pointers. On many platforms these I/O routines are macros or wrappers and not actual functions on their own, resulting in things like: ERROR: "ioread32be" [drivers/spi/xilinx_spi.ko] undefined! ERROR: "iowrite32be" [drivers/spi/xilinx_spi.ko] undefined! ERROR: "iowrite32" [drivers/spi/xilinx_spi.ko] undefined! ERROR: "ioread32" [drivers/spi/xilinx_spi.ko] undefined! If xilinx_spi wants to do this sort of casting, it needs to provide its own wrappers for these, or change how it does accesses completely. I've opted for the first approach, and the attached silly patch does that. If someone with the hardware available wants to give the second option a try that's ok too. In any event, the current code is broken for at least: arm, avr32, blackfin, microblaze, mn10300, and sh.

2010-01-20spi: Add Freescale/Motorola Coldfire QSPI driverSteven King3-0/+651
Add support for the QSPI controller found some on Freescale/Motorola Coldfire MCUs. Full duplex, active high cs, spi modes 0-3 and word sizes 8-16 bits are supported. The hardware drives the MISO, MOSI and SCLK lines, but the chip selects are managed via GPIO and must be configured by the board code. The QSPI controller has an 80 byte buffer which allows us to transfer up to 16 words at a time. For transfers longer than 16 words, we split the buffer in half so we can update in one half while the controller is operating on the other half. Interrupt latencies then ultimately limits our sustained thru-put to something less than half the maximum speed supported by the part.

2010-01-12sata_promise: don't classify overruns as HSM errorsMikael Pettersson1-1/+1
When sata_promise encounters an overrun or underrun error it translates that to a libata AC_ERR_HSM, causing a hard reset. Since over/under-runs were thought to be rare and transient, this action seemed reasonable. Unfortunately it turns out that the controller throws overrun errors when e.g. hal polls a CD or DVD writer containing blank media, causing long sequences of hard resets and retries before EH finally gives up. This patch updates sata_promise to classify over/under-runs as AC_ERR_OTHER instead. This allows libata EH and upper layers to retry or fail the operation as they see fit without the disruption caused by repeated hard resets. This fixes a problem using a DVD-RAM drive with sata_promise, reported by Thomas Schorpp. I also tested it on a DVD-RW drive.

2010-01-11mmc_block: fix queue cleanupAdrian Hunter2-9/+11
The main bug was that 'blk_cleanup_queue()' was called while the block device could still be in use, for example, because the card was removed while files were still open. In addition, to be sure that 'mmc_request()' will get called for all new requests (so it can error them out), the queue is emptied during cleanup. This is done after the worker thread is stopped to avoid racing with it. Finally, it is not a device error for this to be happening, so quiet the (sometimes very many) error messages.

2010-01-11mmc_block: fix probe error cleanup bugJarkko Lavinen1-0/+1
If mmc_blk_set_blksize() fails mmc_blk_probe() the request queue and its thread have been set up and they need to be shut down properly before putting the disk.

2010-01-11mmc_block: add dev_t initialization checkAnna Lemehova1-0/+5
When a card is removed before mmc_blk_probe() has called add_disk(), then the minor field is uninitialized and has value 0. This caused mmc_blk_put() to always release devidx 0 even if 0 was still in use. Then the next mmc_blk_probe() used the first free idx of 0, which oopses in sysfs, since it is used by another card.
