2007-09-23mmc: fix sdio timeout calculationPierre Ossman1-0/+9
SDIO doesn't have a CSD so it uses different timeout values than SD memory. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

2007-09-23sdio: allow for mmc_claim_host to be abortedNicolas Pitre1-6/+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>

2007-09-23sdio: add device id table and matchingPierre Ossman1-6/+52
Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2007-09-23mmc: initialize mmc subsystem with subsys_initcall()Nicolas Pitre1-1/+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.

2007-09-23sdio: split up common and function CIS parsingPierre Ossman5-26/+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>
2007-09-23sdio: link unknown CIS tuples to the sdio_func structureNicolas Pitre3-29/+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>

2007-09-23mmc: enable/disable functions for SDIOPierre Ossman1-0/+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>
2007-09-23mmc: add basic SDIO I/O operationsPierre Ossman2-1/+107
Add command wrappers that simplify register access from SDIO function drivers. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

2007-09-23mmc: at91_mci: disable handling of blocks with size not multiple of 4 bytesMarc Pignat1-0/+8
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>
2007-09-23mmc: add missing printk levelsPierre Ossman1-2/+3
Some printk:s were missing an explicit level. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2007-09-23mmc: remove confusing flagPierre Ossman3-15/+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>
2007-09-23mmc: remove BYTEBLOCK capabilityPierre Ossman6-7/+21
Remove the BYTEBLOCK capability and let the broken hosts fail the requests with -EINVAL instead. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2007-09-23mmc: mmc_set_data_timeout() parameter write is redundantPierre Ossman4-10/+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>
2007-09-23mmc: read ext_csd version numberPierre Ossman1-7/+17
Make sure we do not try to parse a structure we do not understand. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2007-09-23mmc: improve error code feedbackPierre Ossman2-13/+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>
2007-09-23mmc: remove custom error codesPierre Ossman15-196/+190
Convert the MMC layer to use standard error codes and not its own, incompatible values. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2007-09-11bug in AT91 MCI suspend routinesAnti Sullin1-3/+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.

2007-08-23sdhci: tell which spurious interrupt we gotPierre Ossman1-6/+6
When we get unexpected interrupts, also print which interrupt it was. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2007-08-23sdhci: handle data interrupts during commandPierre Ossman2-7/+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>
2007-08-23mmc: ignore bad max block size in sdhciDavid Vrabel1-5/+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>
2007-08-23sdhci: be more cautious about block count registerPierre Ossman1-2/+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>
