* [MMC] Move set_ios debugging into mmc.cRussell King2006-05-048-43/+34
| | | | | | | | Rather than having every driver duplicate the set_ios debugging, provide a single version in mmc.c which can be expanded as we add additional functionality. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [MMC] Correct mmc_request_done commentsRussell King2006-05-041-5/+4
| | | | | | | mmc_request_done should be called at the end of handling a request, not between the data and initial command parts of the request. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [MMC] PXA: reduce the number of lines PXAMCI debug usesRussell King2006-05-021-6/+3
| | | | | | | | | | There's no reason for the PXAMCI debug code to print so many lines - it causes the kernel buffer to overflow when trying to debug this driver. Remove some debug messages which are duplicated by core code, and combine other messages, resulting in fewer characters written to the kernel log.

* [MMC] PXA and i.MX: don't avoid sending stop command on errorRussell King2006-05-022-2/+2
| | | | | | | | Always send a stop command at the end of a data transfer. If we avoid sending the stop command, some cards remain in data transfer mode, and refuse to accept further read/write commands. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [MMC] extend data timeout for writesRussell King2006-05-022-0/+8
| | | | | | | | | The CSD contains a "read2write factor" which determines the multiplier to be applied to the read timeout to obtain the write timeout. We were ignoring this parameter, resulting in the possibility for writes being timed out too early. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] 3485/1: i.MX: MX1 SD/MMC fix of unintentional double start possibilityPavel Pisa2006-04-301-11/+43
| | | | | | | | | | | | | | | | | Patch from Pavel Pisa The clock starting imxmci_start_clock() function contains hardware issue workaround, which repeats start attempt, if SDHC does not react on the first trial. But the second start attempt can be taken even, if the first succeed and test code misses time limited clock running phase due to delay caused by schedule to other task or some another device interrupt. This change enables to detect such situation. The performance is not issue, because usually at full clock rate only about six loops in delay cycle are needed.

* [MMC] pxamci: fix data timeout calculationRussell King2006-04-241-6/+4
| | | | | | | | | | | The MMC layer gives us two parts for the timeout calculation - a fixed timeout in nanoseconds, and a card clock-speed dependent part. The PXA MMC hardware allows for a timeout based on the fixed host clock speed only. This resulted in some cards being given a short timeout, and therefore failing to work.

* [ARM] 3457/1: i.MX: SD/MMC support for i.MX/MX1Pavel Pisa2006-04-024-0/+1174
| | | | | | | | | | | | | | | | | | | | | | | | Patch from Pavel Pisa This patch adds support of i.MX/MX1 SD/MMC controller. It has been significantly redesigned from the original Sascha Hauer's version to support scatter-gather DMA, to conform to latest Pierre Ossman's and Russell King's MMC-SD Linux 2.6.x infrastructure. The handling of all events has been moved to the softirq context and is designed with no busy-looping in mind. Unfortunately some controller bugs has to be overcome by limited looping about 2-20 usec but these are observed only for initial card recognition phase. There are still some missing/missed IRQs problems under heavy load. Help of somebody with access to the full SDHC design information is probably necessary. Regenerated against 2.6.16-git-060402 to solve clash with other patches.

* | [PATCH] Add block_device_operations.getgeo block device methodChristoph Hellwig2006-01-091-19/+6
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | HDIO_GETGEO is implemented in most block drivers, and all of them have to duplicate the code to copy the structure to userspace, as well as getting the start sector. This patch moves that to common code [1] and adds a ->getgeo method to fill out the raw kernel hd_geometry structure. For many drivers this means ->ioctl can go away now. [1] the s390 block drivers are odd in this respect. xpram sets ->start to 4 always which seems more than odd, and the dasd driver shifts the start offset around, probably because of it's non-standard sector size.

| | | | | | | | | | | | | | | | | | | We were passing set_capacity() the capacity we calculated in terms of the number of blocks on the card, which happened to be the right units for 512-byte block cards. However, with 1024-byte block cards, we end up setting the capacity to half the number of blocks. Fix this by shifting by the appropriate amount. Thanks to Todd Blumer for pointing this out. Use get_capacity() to report the card capacity, rather than recalculating it from the CSD information. Finally, use our chosen IO block size for the SET_BLOCKLEN command rather than the CSD read block size. Currently these are equivalent, but will not be in the future.
