blk_end_request: changing mmc (take 4) This patch converts mmc to use blk_end_request interfaces. Related 'uptodate' arguments are converted to 'error'. Cc: Pierre Ossman <drzeus-mmc@drzeus.cx> Signed-off-by: Kiyoshi Ueda <k-ueda@ct.jp.nec.com> Signed-off-by: Jun'ichi Nomura <j-nomura@ce.jp.nec.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com> Kiyoshi Ueda authored and Jens Axboe commited 2008-01-28 10:36:52 +01:00	fd539832c7
mmc: Avoid re-using minor numbers before the original device is closed. Move the code which marks the minor number as free to mmc_blk_put() so that it happens on the final close() (or removal), instead of doing it at removal even when the device is still logically open.

mmc_block: check card state after write Some cards have been reported to signal that they're ready prematurely. Checking both the busy bit and card state solves the issue. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx> Pierre Ossman commited 2007-11-21 18:40:53 +01:00	d198f10198
MMC/SD card driver learns SPI Teaching the MMC/SD block card driver about SPI. - Provide the SPI response type flags with each request issued. - Understand that multiblock SPI writes don't use STOP_TRANSMISSION. - Correct check for APP_CMD failure.

mmc: remove confusing flag The MMC_DATA_MULTI flag never had a proper definition of what it means, so remove it and let the drivers check the block count in the request. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx> Pierre Ossman commited 2007-09-23 09:15:12 +02:00	be0192aae1
mmc: mmc_set_data_timeout() parameter write is redundant The write parameter in mmc_set_data_timeout() is redundant as the data structure contains information about the direction of the transfer.

mmc: remove custom error codes Convert the MMC layer to use standard error codes and not its own, incompatible values. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx> Pierre Ossman commited 2007-09-23 08:46:48 +02:00	17b0429dde

mmc: bounce requests for simple hosts Some hosts cannot do scatter/gather in hardware. Since not doing sg is such a big performance hit, we (optionally) bounce the requests to a simple linear buffer that we hand over to the driver.

mmc: deprecate mmc bus topology The classic MMC bus was defined as multi card bus system, which is reflected in the design in the MMC layer. When SD showed up, the bus topology was abandoned and a star topology (one card per host) was mandated. MMC version 4 has followed this, officially deprecating the bus topology. As we do not have any known users of the bus topology we can remove support for it. This will simplify the code and rectify some incorrect assumptions in the newer additions.
