| * mmc: warn about voltage mismatchesDavid Brownell2008-12-311-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Get rid of a silent failure mode when the MMC/SD host doesn't support the voltages needed to operate a given card, by adding a warning. A 3.3V host and a 3.0V card, for example, no longer need to mysteriously just not work at all. This isn't the best diagnostic; ideally it would also tell what voltage the card and host support (and not just by dumping the bitmasks).

| | | | | | | | | | | | | | | | | | | | The support is implemented via platform data accessors, new module (of_mmc_spi) will be created automatically when the driver compiles on OpenFirmware platforms.

| | | | | | | | | | | | | | | | | | | | If a card encounters an ECC error while reading a sector it will timeout. Instead of reporting the entire I/O request as having an error, redo the I/O one sector at a time so that all readable sectors are provided to the upper layers.

| * drivers/mmc: Move a dereference below a NULL testJulia Lawall2008-12-311-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In each case, if the NULL test is necessary, then the dereference should be moved below the NULL test.

| * ricoh_mmc: Handle newer models of Ricoh controllersphilipl@overt.org2008-12-311-6/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The latest generation of laptops are shipping with a newer model of Ricoh chip where the firewire controller is the primary PCI function but a cardbus controller is also present. The existing code assumes that if a cardbus controller is, present, then it must be the one to manipulate - but the real rule is that you manipulate PCI function 0. This patch adds an additional constraint that the target must be function 0. Signed-off-by: Philip Langdale <philipl@overt.org> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

This allows us to remove a lot of mach/dma.h files which don't contain any useful code.

* [PATCH] beginning of methods conversionAl Viro2008-10-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | To keep the size of changesets sane we split the switch by drivers; to keep the damn thing bisectable we do the following: 1) rename the affected methods, add ones with correct prototypes, make (few) callers handle both. That's this changeset. 2) for each driver convert to new methods. *ALL* drivers are converted in this series. 3) kill the old (renamed) methods. Note that it _is_ a flagday; all in-tree drivers are converted and by the end of this series no trace of old methods remain. The only reason why we do that this way is to keep the damn thing bisectable and allow per-driver debugging if anything goes wrong. New methods: open(bdev, mode) release(disk, mode) ioctl(bdev, mode, cmd, arg) /* Called without BKL */ compat_ioctl(bdev, mode, cmd, arg) locked_ioctl(bdev, mode, cmd, arg) /* Called with BKL, legacy */ Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

During the transfers it does the following: while (fifo_words--) *(host->pio_ptr++) = readl(from_ptr); This is inefficent, as host->pio_ptr is not used in any other part of the transfer but the compiler emits code which does the following: while (fifo_words--) { u32 *ptr = host->pio_ptr; *ptr = readl(from_ptr); ptr++; host->pio_ptr = ptr; } This is obviously a waste of a load and store each time around the loop, which could be up to 16 times depending on how much needs to be transfered. Move the ptr accesses to outside the while loop so that we do not end up reloading/re-writing the pointer. Note, this seems to make the code 16 bytes larger.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To be able to do SDIO the s3cmci driver has to support non-word-sized transfers. Change pio_words into pio_bytes and fix up all the places where it is used. This variant of the patch will not overrun the buffer when reading an odd number of bytes. When writing, this variant will still read past the end of the buffer, but since the driver can't support non-word- aligned transfers anyway, this should not be a problem, since a word-aligned transfer will never cross a page boundary.

However, when NOTBUSY is set, the interrupt handler copies the contents of SR into data_status, overwriting any error bits we may have detected earlier. To avoid this, initialize data_status to 0 before starting a request, and don't overwrite it unless it still contains 0. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
