* [MMC] Clean up wbsd detection handlingPierre Ossman2005-09-121-17/+12
| | | | | | | | The wbsd driver's card detection routing is a bit of a mess. This patch cleans up the routine and makes it a bit more comprihensible. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [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.

* [MMC] support for mmc chip select in wbsdPierre Ossman2005-09-032-15/+52

* [MMC] ios for mmc chip selectPierre Ossman2005-09-031-0/+12
| | | | | | | | | Adds a new ios for setting the chip select pin on MMC cards. Needed on SD controllers which use this pin for other things and therefore cannot have it pulled high at all times.

* [MMC] Add MMC class devicesRussell King2005-08-193-14/+86

* [PATCH] clean up inline static vs static inlineJesper Juhl2005-07-281-1/+1
| | | | | | | | | | | | | | | `gcc -W' likes to complain if the static keyword is not at the beginning of the declaration. This patch fixes all remaining occurrences of "inline static" up with "static inline" in the entire kernel tree (140 occurrences in 47 files). While making this change I came across a few lines with trailing whitespace that I also fixed up, I have also added or removed a blank line or two here and there, but there are no functional changes in the patch.

* [PATCH] MMC: wbsd delayed insertionPierre Ossman2005-07-012-10/+43

Removes the check for high command classes and instead checks that the command classes needed are present. Previous solution killed forward compatibility at no apparent gain.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-1714-0/+5455
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
