* [PATCH] driver core: replace "hotplug" by "uevent"Kay Sievers2006-01-051-2/+2
| | | | | | | | | Leave the overloaded "hotplug" word to susbsystems which are handling real devices. The driver core does not "plug" anything, it just exports the state to userspace and generates events.

* [MMC] Set correct capacity for 1024-byte block cardsRussell King2005-12-231-5/+9
| | | | | | | | | | | | | | | | | | | 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.

* | [PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacksRussell King2005-10-282-6/+6
|/ | | | | | | | | | | | | | | | In PM v1, all devices were called at SUSPEND_DISABLE level. Then all devices were called at SUSPEND_SAVE_STATE level, and finally SUSPEND_POWER_DOWN level. However, with PM v2, to maintain compatibility for platform devices, I arranged for the PM v2 suspend/resume callbacks to call the old PM v1 suspend/resume callbacks three times with each level in order so that existing drivers continued to work. Since this is obsolete infrastructure which is no longer necessary, we can remove it. Here's an (untested) patch to do exactly that.

* [PATCH] sd: initialize SD cardsPierre Ossman2005-09-081-73/+253
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Support for the Secure Digital protocol in the MMC layer. A summary of the legal issues surrounding SD cards, as understood by yours truly: Members of the Secure Digital Association, hereafter SDA, are required to sign a NDA[1] before given access to any specifications. It has been speculated that including an SD implementation would forbid these members to redistribute Linux. This is the basic problem with SD support so it is unclear if it even is a problem since it has no effect on those of us that aren't members. The SDA doesn't seem to enforce these rules though since the patches included here are based on documentation made public by some of the members. The most complete specs[2] are actually released by Sandisk, one of the founding companies of the SDA. Because of this the NDA is considered a non-issue by most involved in the discussions concerning these patches. It might be that the SDA is only interested in protecting the so called "secure" bits of SD, which so far hasn't been found in any public spec. (The card is split into two sections, one "normal" and one "secure" which has an access scheme similar to TPM:s). (As a side note, Microsoft is working to make things easier for us since they want to be able to include the source code for a SD driver in one of their development kits. HP is making sure that the new NDA will allow a Linux implementation. So far only the SDIO specs have been opened up[3]. More will hopefully follow.)

If no MMC cards are found on a bus then the MMC layer proceeds looking for SD cards. Helper functions are extended to handle the special needs of SD cards.
