Suppressing uevents turned out to be a bad idea as it screws up the order of events, making user space very confused. Change the system to use sysfs groups instead. This is a regression that, for some odd reason, has gone unnoticed for some time. It confuses hal so that the block devices (which have the mmc device as a parent) are not registered. End result being that desktop magic when cards are inserted won't work. Signed-off-by: NPierre Ossman <drzeus@drzeus.cx> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

Teach the MMC/SD/SDIO core about using SPI mode. - Use mmc_host_is_spi() so enumeration works through SPI signaling and protocols, not just the native versions. - Provide the SPI response type flags with each request issued, including requests from the new lock/unlock code. - Understand that cmd->resp[0] and mmc_get_status() results for SPI return different values than for "native" MMC/SD protocol; this affects resetting, checking card lock status, and some others. - Understand that some commands act a bit differently ... notably: * OP_COND command doesn't return the OCR * APP_CMD status doesn't have an R1_APP_CMD analogue Those changes required some new and updated primitives: - Provide utilities to access two SPI-only requests, and one request that wasn't previously needed: * mmc_spi_read_ocr() ... SPI only * mmc_spi_set_crc() ... SPI only (override by module parm) * mmc_send_cid() ... for use without broadcast mode - Updated internal routines: * Previous mmc_send_csd() modified into mmc_send_cxd_native(); it uses native "R2" responses, which include 16 bytes of data. * Previous mmc_send_ext_csd() becomes new mmc_send_cxd_data() helper for command-and-data access * Bugfix to that mmc_send_cxd_data() code: dma-to-stack is unsafe/nonportable, so kmalloc a bounce buffer instead. - Modified mmc_send_ext_csd() now uses mmc_send_cxd_data() helper - Modified mmc_send_csd(), and new mmc_spi_send_cid(), routines use those helper routines based on whether they're native or SPI The newest categories of cards supported by the MMC stack aren't expected to work yet with SPI: MMC or SD cards with over 4GB data, and SDIO. All those cards support SPI mode, so eventually they should work too. Signed-off-by: NDavid Brownell <dbrownell@users.sourceforge.net> Signed-off-by: NPierre Ossman <drzeus@drzeus.cx>

Move bus operations to its own file for the sake of clarity. Also delegate sysfs attributes to bus handlers in preparation for other more exotic types. Signed-off-by: NPierre Ossman <drzeus@drzeus.cx>

Since many have the system root on MMC/SD we must allow some foot shooting when it comes to resume. We cannot detect if a card is removed and reinserted during suspend, so the safe approach would be to assume it was, avoiding potential filesystem corruption. This will of course not work if you cannot release the card before suspend. This commit adds a compile time option that makes the MMC layer assume the card wasn't touched if it is redetected upon resume. Signed-off-by: NPierre Ossman <drzeus@drzeus.cx>

Delegate protocol handling to "bus handlers". This allows the core to just handle the task of arbitrating the bus. Initialisation and pampering of cards is now done by the different bus handlers. This design also allows MMC and SD (and later SDIO) to be more cleanly separated, allowing easier maintenance. Signed-off-by: NPierre Ossman <drzeus@drzeus.cx>

The MMC layer uses the standard work queue for doing card detection. As this queue is shared with other crucial subsystems, the effects of a long (and perhaps buggy) detection can cause the system to be unusable. E.g. the keyboard stops working while the detection routine is running. The solution is to add a specific mmc work queue to run the detection code in. This is similar to how other subsystems handle detection (a full kernel thread is the most common theme).

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!
