mmc: fix data timeout for SEND_EXT_CSD

2009-03-08T13:46:04Z

Commit 0d3e0460f307e84904968aad6cff97bd688583d8 "MMC: CSD and CID timeout values" inadvertently broke the timeout for the MMC command SEND_EXT_CSD. This patch puts it back again. Depending on the characteristics of the controller, this bug may prevent the use of MMC cards. Signed-off-by: Adrian Hunter Signed-off-by: Pierre Ossman

mmc: warn about voltage mismatches

2008-12-31T18:27:18Z

Get rid of a silent failure mode when the MMC/SD host doesn't support the voltages needed to operate a given card, by adding a warning. A 3.3V host and a 3.0V card, for example, no longer need to mysteriously just not work at all. This isn't the best diagnostic; ideally it would also tell what voltage the card and host support (and not just by dumping the bitmasks). Signed-off-by: David Brownell Signed-off-by: Pierre Ossman

mmc: Add mmc_vddrange_to_ocrmask() helper function

2008-12-31T17:18:13Z

This function sets the OCR mask bits according to provided voltage ranges. Will be used by the mmc_spi OpenFirmware bindings. Signed-off-by: Anton Vorontsov Signed-off-by: Pierre Ossman

mmc: increase SD write timeout for crappy cards

2008-11-08T20:36:59Z

It seems that some cards are slightly out of spec and occasionally will not be able to complete a write in the alloted 250 ms [1]. Incease the timeout slightly to allow even these cards to function properly. [1] http://lkml.org/lkml/2008/9/23/390 Signed-off-by: Pierre Ossman

sdio: give sdio irq thread a host specific name

2008-10-12T09:04:30Z

There is one thread per host controller so make sure they all get unique names. Signed-off-by: Pierre Ossman

sdio: make sleep on error interruptable

2008-10-12T09:04:28Z

Make sure we can be woken from the forced sleep that is done on errors. Removing a card often results in -ENOMEDIUM or -EILSEQ so we previously locked up the removal process for a second. We could completely exit on -ENOMEDIUM, but it might be a transient glitch so treat it like any other error. Signed-off-by: Pierre Ossman
