* mmc: remove card upon suspendPierre Ossman2007-05-01
| | | | | | | Suspending MMC/SD cards (versus removing and readding them) is an inherently unsafe operation and has even been broken for some time. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* mmc: allow suspended block driver to be removedPierre Ossman2007-05-01
| | | | | | | | Make sure we don't deadlock when removing a suspended block queue, something that might happen if the card is removed during suspend. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* mmc: Flush pending detects on host removalPierre Ossman2007-05-01
| | | | | | | | | Make sure we kill of any pending detection runs when the host is removed instead of when it is freed. Also add some debugging to make sure the driver doesn't queue up more detection after it has removed the host. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* mmc: Move host and card drivers to subdirsPierre Ossman2007-05-01
| | | | | | | Clean up the drivers/mmc directory by moving card and host drivers into subdirectories. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* mmc: Move queue functions to mmc_blockPierre Ossman2007-05-01
| | | | | | | The mmc block queue functions are tailored for the mmc_block driver, so move those functions into that module. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* mmc: Move "present" markingPierre Ossman2007-05-01
| | | | | | | The "present" state indicates that the card is a registered device, so it is more clear to put it together with the actual registration. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* mmc: Move OCR bit definesPierre Ossman2007-05-01
| | | | | | | All host drivers were #include:ing mmc/protocol.h just to get access to the OCR bit defines. Move these to host.h instead. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* mmc: add type field to cardsPierre Ossman2007-05-01
| | | | | | | Split out the type of card into its own field as it hardly qualifies as a state. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* mmc: MMC sector based cardsPierre Ossman2007-05-01
| | | | | | | Support for MMC 4.2 sector based cards. This tweaks the init a bit and reads a new field out of the EXT_CSD. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* mmc: use right timing mode constantPierre Ossman2007-05-01
| | | | | | Fix copy-n-paste error. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* tifm: add missing include for DMA_32BIT_MASKAndrew Morton2007-05-01
| | | | | | | | | | sparc64: drivers/misc/tifm_7xx1.c: In function `tifm_7xx1_probe': drivers/misc/tifm_7xx1.c:294: error: `DMA_32BIT_MASK' undeclared Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* tifm: layout fixes, small changes to comments and printfsAlex Dubov2007-05-01
| | | | | | | Cosmetic changes to the code. Signed-off-by: Alex Dubov <oakad@yahoo.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* tifm_sd: implement software scatter-gatherAlex Dubov2007-05-01
| | | | | | | | | | | It was found that delays associated with issue and completion of the commands severely limit performance of the new, fast SD cards. To alleviate this issue scatter-gather emulation in software is implemented for both dma and pio transfer modes. Non-block aligned and high memory sg entries are accounted for. Signed-off-by: Alex Dubov <oakad@yahoo.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* tifm_sd: fix resume handlerAlex Dubov2007-05-01
| | | | | | | | | Resume should not explicitly check for media type. Instead, it may relay on success of socket initialization. Small changes are introduced to tifm_sd_initialize to make it more robust. Signed-off-by: Alex Dubov <oakad@yahoo.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* tifm_sd: replace command completion state machine with full checkingAlex Dubov2007-05-01
| | | | | | | | | State machine used to to track mmc command state was found to be fragile and unreliable, making many cards unusable. The safer solution is to perform all needed checks at every card event. Signed-off-by: Alex Dubov <oakad@yahoo.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* tifm_sd: merge dma and pio request processing pathsAlex Dubov2007-05-01
| | | | | | | | To allow for switching of trasfer mode (dma/pio) on a per-request basis, pio and dma request issue and completion function are now merged. Signed-off-by: Alex Dubov <oakad@yahoo.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* tifm_sd: separate command flags, socket flags and register bit masksAlex Dubov2007-05-01
| | | | | | | | | | host->flags variable was hosting a collection of bits with different semantics. For clarity, hardware bit masks are now defined as macros, socket flags represented as bit fields and flags (now cmd_flags) only hosts command processing modifiers. Signed-off-by: Alex Dubov <oakad@yahoo.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* tifm_sd: remove wait for power off on removeAlex Dubov2007-05-01
| | | | | | | | | This wait was needed because of the mmc layer failure to wait for completion of all outstanding commands before host removal. It should be fixed now in the mmc layer. Signed-off-by: Alex Dubov <oakad@yahoo.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* tifm_sd: remove tifm_sd_terminate functionAlex Dubov2007-05-01
| | | | | | | | tifm_sd_terminate can only lawfully be called on device removal so it can be merged with tifm_sd_remove. Signed-off-by: Alex Dubov <oakad@yahoo.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* tifm: add sysfs attribute for tifm devicesAlex Dubov2007-05-01
| | | | | | | A sysfs attribute reflecting current media type is added. Signed-off-by: Alex Dubov <oakad@yahoo.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* tifm_7xx1: fix adapter resume functionAlex Dubov2007-05-01
| | | | | | | | | | Fixes to the adapter resume function to correctly handle all possible cases: 1. Card is removed during suspend 2. Card is inserted during suspend into previously empty socket 3. Card is replaced during suspend by same or different media type card. Signed-off-by: Alex Dubov <oakad@yahoo.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* tifm: move common device management tasks from tifm_7xx1 to tifm_coreAlex Dubov2007-05-01
| | | | | | | | Some details of the device management (create, add, remove) are really belong to the tifm_core, as they are not hardware specific. Signed-off-by: Alex Dubov <oakad@yahoo.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

* tifm_7xx1: improve card detection routineAlex Dubov2007-05-01
| | | | | | | | Remove unneeded conditions and change a sleeping regime a little in the card type detection routine. Signed-off-by: Alex Dubov <oakad@yahoo.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* tifm: replace per-adapter kthread with freezeable workqueueAlex Dubov2007-05-01
| | | | | | | | | Freezeable workqueue makes sure that adapter work items (device insertions and removals) would be handled after the system is fully resumed. Previously this was achieved by explicit freezing of the kthread. Signed-off-by: Alex Dubov <oakad@yahoo.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* tifm: simplify bus match and uevent handlersAlex Dubov2007-05-01
| | | | | | | | Remove code duplicating the kernel functionality and clean up data structures involved in driver matching. Signed-off-by: Alex Dubov <oakad@yahoo.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* tifm: use bus methods to handle probe/remove instead of driver ones.Alex Dubov2007-05-01

* tifm: hide details of interrupt processing from socket driversAlex Dubov2007-05-01
| | | | | | | | | Instead of passing transformed value of adapter interrupt status to socket drivers, implement two separate callbacks - one for card events and another for dma events. Signed-off-by: Alex Dubov <oakad@yahoo.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* wbsd: remove block crc testPierre Ossman2007-05-01
| | | | | | | | | Block completion interrupts occur faster than we can process them, so just ignore them competely. Commit also fixes up some incorrect register defines. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* mmc: enforce correct sg listPierre Ossman2007-05-01
| | | | | | | | Now that we've fixed our only offender when it comes to strange sg list, add a check so that future users keep the sg list proper with regard to transfer size. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* mmc: cull sg list to match mmc request sizeAlex Dubov2007-05-01
| | | | | | | | | | | | mmc layer may introduce additional (compared to block layer) limits on request size. Culling of the sg list to match adjusted request size simplifies the handling of such cases in the low level driver, allowing it to skip block count checks while processing sg entries. (fixes for wbsd and sdhci by Pierre Ossman) Signed-off-by: Alex Dubov <oakad@yahoo.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* libata: honour host controllers that want just one hostLinus Torvalds2007-04-30
| | | | | | | | | | | | | | | | | | | | The Marvell IDE interface on my machine would hit a BUG_ON() in lib/iomem.c because it was calling ata_pci_init_one() specifying just a single port on the host, but that would actually end up trying to initialize two ports, the second one with bogus information. This fixes "ata_pci_init_one()" so that it actually passes down the n_ports variable that it got from the low-level driver to the host allocation routine ("ata_host_alloc_pinfo()"), which results in the ATA layer actually having the correct port number information. And in order to make it all work, I also needed to fix a few places that had incorrectly hard-coded the fact that a host always had exactly two ports (both ata_pci_init_bmdma() and ata_request_legacy_irqs() would just always iterate over both ports).

* power management: implement pm_ops.valid for everybodyJohannes Berg2007-04-30
| | | | | | | | | | | | | | | | | | | | | | Almost all users of pm_ops only support mem sleep, don't check in .valid and don't reject any others in .prepare so users can be confused if they check /sys/power/state, especially when new states are added (these would then result in s-t-r although they're supposed to be something different). This patch implements a generic pm_valid_only_mem function that is then exported for users and puts it to use in almost all existing pm_ops.
