[MMC] Always use a sector size of 512 bytes

2006-09-07T15:01:30+00:00

Both MMC and SD specifications specify (although a bit unclearly in the MMC case) that a sector size of 512 bytes must always be supported by the card. Cards can report larger "native" size than this, and cards >= 2 GB even must do so. Most other readers use 512 bytes even for these cards. We should do the same to be compatible.

[MMC] Cleanup 385e3227d4d83ab13d7767c4bb3593b0256bf246

Rather than having two places which independently calculate the timeout for data transfers, make it a library function instead. Signed-off-by: Russell King Acked-by: Pierre Ossman

[ARM] 3751/1: i.MX/MX1 SD/MMC use 512 bytes request for SCR read

2006-09-07T14:53:29+00:00

Patch from Pavel Pisa This is another approach to SDHC deficiency workaround. It seems, that previous solution based on 16 bytes (FIFO length size) read is still timing sensitive on genirq and fully preemptive kernels. The new solution is backuped by M9328 UM statement, that only 512 byte block are working properly and by 2.4.26 FreeScale's SDHC code. Jay Monkman reports significant improvement on code based on this driver after applying this change on MX21 as well. Signed-off-by: Pavel Pisa Signed-off-by: Russell King

[MMC] Fix SD timeout calculation

2006-09-07T12:18:40+00:00

Secure Digital cards use a different algorithm to calculate the timeout for data transfers. Using the MMC one works often, but not always. Signed-off-by: Pierre Ossman Signed-off-by: Russell King

[MMC] Another stray 'io' reference

Another misuse of the global 'io' variable instead of the local 'base'. Signed-off-by: Pierre Ossman Signed-off-by: Russell King

[MMC] Fix base address configuration in wbsd

2006-08-06T20:44:48+00:00

There were some confusion about base I/O variables in the wbsd driver. Seems like things have been working on shear luck so far. The global 'io' variable (used when manually configuring the resources) was used instead of the local 'base' variable. Signed-off-by: Pierre Ossman Signed-off-by: Russell King

[ARM] 3744/1: MMC: mmcqd gets stuck when block queue is plugged

2006-08-06T08:58:22+00:00

Patch from Juha [��l� When the block queue is plugged, mq->req must be set to NULL. Otherwise mq->req might be left non-NULL, even though mmcqd is not processing a request, thus preventing the MMC queue thread from being woken up when new requests do arrive.

[MMC] Change SDHCI version error to a warning

2006-07-13T15:17:46+00:00

O2 Micro's controllers have a larger specification version value and are therefore denied by the driver. When bypassing this check they seem to work fine. This patch makes the code a bit more forgiving by changing the error to a warning. Signed-off-by: Pierre Ossman Signed-off-by: Russell King

[MMC] Fix incorrect register access

[PATCH] lockdep: annotate on-stack completions, mmc

2006-07-03T22:27:10+00:00

lockdep needs to have the waitqueue lock initialized for on-stack waitqueues implicitly initialized by DECLARE_COMPLETION(). Annotate mmc_wait_for_req()'s on-stack completion accordingly. Has no effect on non-lockdep kernels. Signed-off-by: Ingo Molnar Cc: Arjan van de Ven Cc: Russell King Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
