* sdio: core support for SDIO function interruptNicolas Pitre2007-09-233-1/+246

* sdio: allow for mmc_claim_host to be abortedNicolas Pitre2007-09-231-6/+16
| | | | | | | | | | It is sometimes necessary to give up on trying to claim the host lock, especially if that happens in a thread that has to be stopped. While at it, fix the description for mmc_claim_host() which was wrong. Signed-off-by: Nicolas Pitre <npitre@mvista.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

* mmc: initialize mmc subsystem with subsys_initcall()Nicolas Pitre2007-09-231-1/+1
| | | | | | | | | | | | | | | | | | | | The problem is that the sdio_bus must be registered before any SDIO drivers are registered against it otherwise the kernel sulks. Because the sdio_bus registration happens through module_init (equivalent to device_initcall), then any SDIO drivers linked before the SDIO core code in the kernel will be initialized first. Upcoming SDIO function drivers are likely to be located outside the drivers/mmc directory as it is common practice to group drivers according to their function rather than the bus they use. SDIO drivers are therefore likely to appear at random location in the kernel link. To make sure the sdio_bus is always initialized before any SDIO drivers, let's move the MMC init to the subsys_initcall level.

* sdio: split up common and function CIS parsingPierre Ossman2007-09-235-26/+193
| | | | | | | | Add a more clean separation between global, common CIS information and the function specific one as we need the common information in places where no specific function is specified. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* sdio: link unknown CIS tuples to the sdio_func structureNicolas Pitre2007-09-233-29/+58
| | | | | | | | | This way those tuples that the core cares about are consumed by the core code, and tuples that only function drivers might make sense of are available to drivers. Signed-off-by: Nicolas Pitre <npitre@mvista.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

* mmc: enable/disable functions for SDIOPierre Ossman2007-09-231-0/+93
| | | | | | | | Like many other buses, the devices (functions) on the SDIO bus must be enabled before they can be used. Add functions that allow drivers to do so. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* mmc: add basic SDIO I/O operationsPierre Ossman2007-09-232-1/+107

| | | | | | | | This kind of transfer is not supported, so don't advertise it and make it fail early. Signed-off-by: Marc Pignat <marc.pignat@hevs.ch> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* mmc: add missing printk levelsPierre Ossman2007-09-231-2/+3
| | | | | | Some printk:s were missing an explicit level. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* mmc: remove confusing flagPierre Ossman2007-09-233-15/+16
| | | | | | | | The MMC_DATA_MULTI flag never had a proper definition of what it means, so remove it and let the drivers check the block count in the request. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* mmc: remove BYTEBLOCK capabilityPierre Ossman2007-09-236-7/+21
| | | | | | | Remove the BYTEBLOCK capability and let the broken hosts fail the requests with -EINVAL instead. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* mmc: mmc_set_data_timeout() parameter write is redundantPierre Ossman2007-09-234-10/+8
| | | | | | | | The write parameter in mmc_set_data_timeout() is redundant as the data structure contains information about the direction of the transfer. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

* mmc: improve error code feedbackPierre Ossman2007-09-232-13/+36
| | | | | | | Now that we use "normal" error codes, improve the reporting and response to error codes in the core. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* mmc: remove custom error codesPierre Ossman2007-09-2315-196/+190
| | | | | | | Convert the MMC layer to use standard error codes and not its own, incompatible values. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* bug in AT91 MCI suspend routinesAnti Sullin2007-09-111-3/+3
| | | | | | | | | | | | This patch fixes a bug in AT91 mmc host driver, that enables the wakeup from suspend on card detection pin even if the card detect pin is not available (==0). If not card detection pin is defined, IRQ0 == FIQ gets enabled and if some activity is present on that pin, the system gets a FIQ request, that causes a crash.

* sdhci: tell which spurious interrupt we gotPierre Ossman2007-08-231-6/+6
| | | | | | When we get unexpected interrupts, also print which interrupt it was. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* sdhci: handle data interrupts during commandPierre Ossman2007-08-232-7/+22
| | | | | | | | It is fully legal for a controller to start issuing data related interrupts before it has signalled that the command has completed. Make sure the driver actually can handle this. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* mmc: ignore bad max block size in sdhciDavid Vrabel2007-08-231-5/+4
| | | | | | | | | Some SDHC cards report an invalid maximum block size, in these cases assume they support block sizes up to 512 bytes instead of returning an error. Signed-off-by: David Vrabel <david.vrabel@csr.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* sdhci: be more cautious about block count registerPierre Ossman2007-08-231-2/+2
| | | | | | | The block count register shouldn't be trusted for single block transfers, so avoid using it completely when calculating transferred bytes. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

| * mmc: proper debugging output in corePierre Ossman2007-07-261-8/+40
| | | | | | | | | | | | | | | | Make sure that the debugging output in the core is complete. This should allow us to clean up all the extra debug output that each and every other host driver seems to contain. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
| * mmc: be more verbose about card insertions/removalPierre Ossman2007-07-263-2/+35
| | | | | | | | | | | | | | Let the user know that the kernel actually detected the card by printing some basic information in dmesg. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
| * mmc: Don't hold lock when releasing an added cardPierre Ossman2007-07-262-10/+16
| | | | | | | | | | | | | | | | When the card has been added to the device model, it might be bound to a card driver. Therefore, we have to release the host lock when trying to remove it as we otherwise might deadlock with the driver. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

| | | | | | | | | | | | | | | | In the normal case, the host lock can be claimed directly. When it cannot, the caller will sleep. Make sure we don't have any latent bugs by always calling might_sleep(). Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

| * mmc: check error bits before command completionPierre Ossman2007-07-261-13/+10
| | | | | | | | | | | | | | | | Some controllers signal "command complete" even on failures (which they are allowed to do according to the spec). Make sure we check the error bits first so we don't get any false positives. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* | [BLOCK] Get rid of request_queue_t typedefJens Axboe2007-07-241-4/+4
|/ | | | | | | | | Some of the code has been gradually transitioned to using the proper struct request_queue, but there's lots left. So do a full sweet of the kernel and get rid of this typedef and replace its uses with the proper type. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
* sdhci: make sure to clear the error interruptPierre Ossman2007-07-202-0/+3
| | | | | | | | The controller has a bit indicating that one of the higher bits (the error bits) are set. A previous bug caused this bit to be masked, but since that bug has been fixed we have to clear it explicictly. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
