2008-05-17at91_mci: minor cleanupMarc Pignat
MMC_POWER_ON is a noop, no need to set the power pin again. Signed-off-by: Marc Pignat <marc.pignat@hevs.ch> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2008-04-15mmc: fix platform driver hotplug/coldplugKay Sievers
Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable MMC host platform drivers, to re-enable auto loading. Also, add missing owner declarations in driver init.

2008-02-08at91_mci: use generic GPIO callsDavid Brownell
Update the AT91 MMC driver to use the generic GPIO calls instead of the AT91-specific calls; and to request (and release) those GPIO signals. That required updating the probe() fault cleanup codepaths. Now there is a single sequence for freeing resources, in reverse order of their allocation. Also that code uses use dev_*() for messaging, and has less abuse of KERN_ERR. Likewise with updating remove() cleanup. This had to free the GPIOs, and while adding that code I noticed and fixed two other problems: it was poking at a workqueue owned by the mmc core; and in one (rare) case would try freeing an IRQ that it didn't allocate.

2007-10-17mmc: at91_mci: cleanup: use MCI_ERRORSAndrew Victor
A small MMC driver cleanup. Use the defined AT91_MCI_ERRORS in at91_mci_completed_command() instead of specifying all the error bits individually.

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: 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: 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.

2007-07-09mmc: at91_mci: fix hanging and rework to match flowchartsNicolas Ferre
Fixes hanging using multi block operations (seen during CMD25). Follows closely the datasheet flowcharts. This piece of code handles better big file writing. I had to take care of the notbusy signal during write (at91_mci_handle_cmdrdy function) and to rearrange the AT91_MCI_ENDRX and AT91_MCI_RXBUFF flag usage.

Fix compilation error by removing command decoding from at91_mci.c driver. Decoding commands in the host driver is the wrong way. Signed-off-by: Marc Pignat <marc.pignat@hevs.ch> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
