2008-12-10omap mmc: Add low-level initialization for hsmmc controllerTony Lindgren1-1/+1
Add low-level initialization for hsmmc controller. Merged into this patch patch are various improvments and board support by Grazvydas Ignotas and David Brownell. Also change wire4 to be wires, as some newer controllers support 8 data lines.

2008-12-10omap mmc: Add better MMC low-level initTony Lindgren1-3/+4
This will simplify the MMC low-level init, and make it more flexible to add support for a newer MMC controller in the following patches. The patch rearranges platform data and gets rid of slot vs controller confusion in the old data structures. Also fix device id numbering in the clock code. Some code snippets are based on an earlier patch by Russell King <linux@arm.linux.org.uk>. Cc: Pierre Ossman <drzeus-mmc@drzeus.cx> Signed-off-by: Tony Lindgren <tony@atomide.com>

2008-11-29[ARM] Hide ISA DMA API when ISA_DMA_API is unsetRussell King1-1/+1
When ISA_DMA_API is unset, we're not implementing the ISA DMA API, so there's no point in publishing the prototypes via asm/dma.h, nor including the machine dependent parts of that API. This allows us to remove a lot of mach/dma.h files which don't contain any useful code. Unfortunately though, some platforms put their own private non-ISA definitions into mach/dma.h, so we leave these behind and fix the appropriate #include statments.

2008-11-08mmc: increase SD write timeout for crappy cardsPierre Ossman1-1/+5
It seems that some cards are slightly out of spec and occasionally will not be able to complete a write in the alloted 250 ms [1]. Incease the timeout slightly to allow even these cards to function properly. [1] http://lkml.org/lkml/2008/9/23/390 Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2008-10-21[PATCH] beginning of methods conversionAl Viro1-2/+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>

2008-10-15s3cmci: Add Ben Dooks/Simtec Electronics to header & copyrightben@fluff.org.uk1-1/+4
Since the original authour (Thomas Kleffel) has been too busy to merge the s3cmci driver and keep it up to date, I (mostly as part of my role with Simtec Electronics) got the driver to a mergable state and have been maintaining it since I think that I should be added to the header. Also add a copyright statement for the new work. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2008-10-15s3cmci: fix continual accesses to host->pio_ptrben@fluff.org.uk1-2/+8
The s3cmci driver uses the host->pio_ptr field to point to the current position into the buffer for data transfer. 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.

2008-10-15s3cmci: Support transfers which are not multiple of 32 bits.Christer Weinigel2-28/+54
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. This has been tested with a CSR SDIO Bluetooth Type A device on a Samsung S3C24A0 processor.

General errors, such as timeouts during probe do not need to be sent to the console, so move them down to be included if the debug is enabled.

2008-10-12sdhci: 'scratch' may be used uninitializedSteven Noonan1-1/+1
The variable 'scratch' is always initialized before it's used. The conditional which is responsible for initialization of 'scratch' will always evaluate 'true' when the first loop iteration occurs, and thus, it's properly initialized. GCC doesn't see this, of course, so using the uninitialized_var() macro seems to work for silencing this case.

2008-10-12sdio: make sleep on error interruptablePierre Ossman1-4/+9
Make sure we can be woken from the forced sleep that is done on errors. Removing a card often results in -ENOMEDIUM or -EILSEQ so we previously locked up the removal process for a second. We could completely exit on -ENOMEDIUM, but it might be a transient glitch so treat it like any other error. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2008-10-12sdhci: reduce card detection delayPierre Ossman1-1/+1
The card detection delay was added early when the behaviour of the card interrupt was still very much unknown (i.e. before there was a public specification). As it is now known that it is a debounced signal, reduce the delay to something more sensible. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
