2008-12-31mmc_spi: Add support for OpenFirmware bindingsAnton Vorontsov3-1/+155
The support is implemented via platform data accessors, new module (of_mmc_spi) will be created automatically when the driver compiles on OpenFirmware platforms. Link-time dependency will load the module automatically. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

2008-12-31drivers/mmc: Move a dereference below a NULL testJulia Lawall1-1/+2
In each case, if the NULL test is necessary, then the dereference should be moved below the NULL test. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type T; expression E; identifier i,fld; statement S; @@ - T i = E->fld; + T i; ... when != E when != i if (E == NULL) S + i = E->fld; // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2008-12-31sdhci: handle built-in sdhci with modular leds classPierre Ossman1-6/+11
As reported by Randy Dunlap, having sdhci built-in and LEDs class as a module resulted in undefined symbols. Change the code to handle that case properly (by not having LEDs class support in sdhci). Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

2008-12-31ricoh_mmc: Handle newer models of Ricoh controllersphilipl@overt.org1-6/+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>
2008-12-31sdhci: activate led support also when moduleÉric Piel2-7/+7
CONFIG_LEDS_CLASS is defined only if led-class is built-in, otherwise when it is a module the option is called CONFIG_LEDS_CLASS_MODULE. Led support should also be activated in this case. Signed-off-by: Eric Piel <eric.piel@tremplin-utc.net> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2008-12-31pci: use pci_ioremap_bar() in drivers/mmcArjan van de Ven1-1/+1
Use the new pci_ioremap_bar() function in drivers/mmc. pci_ioremap_bar() just takes a pci device and a bar number, with the goal of making it really hard to get wrong, while also having a central place to stick sanity checks.

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.

2008-10-15s3cmci: 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.

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.

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.

2008-10-07atmel-mci: Initialize BLKR before sending data transfer commandHaavard Skinnemoen1-2/+4
The atmel-mci driver sometimes fails data transfers like this: mmcblk0: error -5 transferring data end_request: I/O error, dev mmcblk0, sector 2749769 end_request: I/O error, dev mmcblk0, sector 2749777 It turns out that this might be caused by the BLKR register (which contains the block size and the number of blocks being transfered) being initialized too late. This patch moves the initialization of BLKR so that it contains the correct value before the block transfer command is sent. This error is difficult to reproduce, but if you insert a long delay (mdelay(10) or thereabouts) between the calls to atmci_start_command() and atmci_submit_data(), all transfers seem to fail without this patch, while I haven't seen any failures with this patch.
