mmc: fix all hangs related to mmc/sd card insert/removal during suspend/resume

2011-05-09T22:55:31Z

commit 4c2ef25fe0b847d2ae818f74758ddb0be1c27d8e upstream. If you don't use CONFIG_MMC_UNSAFE_RESUME, as soon as you attempt to suspend, the card will be removed, therefore this patch doesn't change the behavior of this option. However the removal will be done by pm notifier, which runs while userspace is still not frozen and thus can freely use del_gendisk, without the risk of deadlock which would happen otherwise. Card detect workqueue is now disabled while userspace is frozen, Therefore if you do use CONFIG_MMC_UNSAFE_RESUME, and remove the card during suspend, the removal will be detected as soon as userspace is unfrozen, again at the moment it is safe to call del_gendisk. Tested with and without CONFIG_MMC_UNSAFE_RESUME with suspend and hibernate.

mmc: add 'enable' and 'disable' methods to mmc host

2009-09-23T14:39:33Z

MMC hosts that support power saving can use the 'enable' and 'disable' methods to exit and enter power saving states. An explanation of their use is provided in the comments added to include/linux/mmc/host.h. Signed-off-by: Adrian Hunter Acked-by: Matt Fleming Cc: Ian Molton Cc: "Roberto A.

mmc: Export internal host state through debugfs

2008-07-26T23:26:16Z

When CONFIG_DEBUG_FS is set, create a few files under /sys/kernel/debug containing information about an mmc host's internal state. Currently, just a single file is created, "ios", which contains information about the current operating parameters for the bus (clock speed, bus width, etc.) Host drivers can add additional files and directories under the host's root directory by passing the debugfs_root field in struct mmc_host as the 'parent' parameter to debugfs_create_*.

mmc: set controller name early

2008-04-18T18:05:26Z

Reorganise code so that mmc_hostname() works directly after allocation. That way host drivers can use that name for resource allocations and messages during probing. Signed-off-by: Pierre Ossman

mmc: use correct unregister function for led trigger

2007-10-12T20:48:46Z

We register a simple trigger so make sure we use the corresponding unregister function. (Also means we get a dummy function when triggers aren't compiled in) Signed-off-by: Pierre Ossman

mmc: add led trigger

2007-09-24T05:15:48Z

Add a led trigger for each host controller that indicates if there is a request active on the controller. Signed-off-by: Pierre Ossman
