2008-07-15MMC: S3C24XX: Refuse incorrectly aligned transfersBen Dooks1-0/+11
The hardware does not support any multi-block transfers with an block-size that is not 32bit aligned. Also the driver itself does not support single block non-32bit transfers either. Ensure that the s3cmci_setup_data() returns the appropriate error if we encounter this. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2008-07-15MMC: S3C24XX: Update error debugging.Ben Dooks1-2/+10
Add better debugging to show where errors are being generated, as some error codes can come from several different code paths. Also fix the error return path from s3cmci_setup_data() to return the error it returned to the request. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2008-07-15MMC: S3C24XX: Add media presence test to request handling.Ben Dooks1-1/+18
Ensure that we have physical media present before attempting to send a request to a card. This ensures that we do not get flooded by errors from commands that can never be completed timing out. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2008-07-15MMC: S3C24XX: Fix use of msecs where jiffies are neededBen Dooks1-1/+1
mmc_detect_change() takes jiffies, not msecs. Convert the previous value of msecs into jiffies before calling. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2008-07-15MMC: S3C24XX: Add MODULE_ALIAS() entries for the platform devicesBen Dooks1-0/+3
Add MODULE_ALIAS() declerations for all the supported platform devices for this driver. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2008-07-15MMC: S3C24XX: Fix s3c2410_dma_request() return code check.Ben Dooks1-1/+1
The driver should be checking for a negative error code from s3c2410_dma_request(), not non-zero. Newer kernels now return the DMA channel number that was allocated by the request. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2008-07-15MMC: S3C24XX: Allow card-detect on non-IRQ capable pinBen Dooks1-11/+17
Add support to the S3C24XX MMC driver to have the card detect be on a pin that is not IRQ capable. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

Fix a crash if host->mrq->data is NULL on ending a transfer. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2008-07-15MMC: S3C24XX: Add support to invert write protect lineBen Dooks1-2/+9

2008-07-15MMC: S3C24XX: Add platform data for MMC/SD driverBen Dooks1-3/+41
This patch adds platform data support to the s3mci driver. This allows flexible board-specific configuration of set_power, card detect and read only pins. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
