2007-09-23sdio: add /proc interface to sdio_uart driverNicolas Pitre
This mimics what the serial_core does. Useful for diagnostics. Signed-off-by: Nicolas Pitre <npitre@mvista.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2007-09-23sdio: UART/GPS driverNicolas Pitre
This currently only accepts the GPS class since that's all I have for testing. Tested with a Matsushita GPS and gpsd version 2.34. Signed-off-by: Nicolas Pitre <npitre@mvista.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2007-09-23sdio: core support for SDIO function interruptNicolas Pitre

2007-09-23sdio: allow for mmc_claim_host to be abortedNicolas Pitre
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>

Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2007-09-23mmc: initialize mmc subsystem with subsys_initcall()Nicolas Pitre
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 Ossman
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 Pitre
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>
2007-09-23sdio: initial CIS parsing codeNicolas Pitre

Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2007-09-23mmc: enable/disable functions for SDIOPierre Ossman
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 Ossman
Add command wrappers that simplify register access from SDIO function drivers. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2007-09-23mmc: add SDIO driver handlingPierre Ossman
Add basic driver handling to the SDIO device model. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2007-09-23mmc: basic SDIO device modelPierre Ossman
Add the sdio bus type and basic device handling. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2007-09-23mmc: detect SDIO cardsPierre Ossman
Really basic init sequence for SDIO cards. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2007-09-23mmc: at91_mci: disable handling of blocks with size not multiple of 4 bytesMarc Pignat
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 Ossman
Some printk:s were missing an explicit level. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2007-09-23mmc: remove confusing flagPierre Ossman
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 Ossman
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 Ossman
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 Ossman
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 Ossman
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 Ossman
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 Sullin
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 Ossman
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 Ossman
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 Vrabel
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 Ossman
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>

2007-08-09mmc: reorganize bounce buffer initPierre Ossman
Reorganize the code that initializes mmc_block's bounce buffer in order to avoid warnings when MMC_BLOCK_BOUNCE isn't used. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

2007-07-26mmc: remove redundant debug information from sdhci and wbsdPierre Ossman
Remove the extra debugging output that now is properly printed by the core. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2007-07-26mmc: proper debugging output in corePierre Ossman
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>
2007-07-26mmc: be more verbose about card insertions/removalPierre Ossman
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>
2007-07-26mmc: Don't hold lock when releasing an added cardPierre Ossman
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>
2007-07-26mmc: add a might_sleep() to mmc_claim_host()Pierre Ossman
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>

2007-07-26sdhci: add support to ENE-CB714Leandro Dorileo
Added its pci_id and implemented a quirk for it because this controller needs to reset cmd and data when setting ios. Signed-off-by: Leandro Dorileo <dorileo@ossystems.com.br> Signed-off-by: Otavio Salvador <otavio@ossystems.com.br> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2007-07-26mmc: check error bits before command completionPierre Ossman
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>
