2007-10-27mmc_spi: Fix mmc-over-spi regressionDavid Brownell1-19/+33
Patch 49dce689ad4ef0fd1f970ef762168e4bd46f69a3 changed the sysfs data structures for SPI in a way which broke the MMC-over-SPI host driver. This patch fixes that regression by changing the scheme used to keep from knowingly trying to use a shared bus segment, and updates the adjacent comments slightly to better explain the issue.

2007-10-23[PATCH] Fix breakage after SG cleanupsRalf Baechle1-0/+1
Commits 58b053e4ce9d2fc3023645c1b96e537c72aa8d9a ("Update arch/ to use sg helpers") 45711f1af6eff1a6d010703b4862e0d2b9afd056 ("[SG] Update drivers to use sg helpers") fa05f1286be25a8ce915c5dd492aea61126b3f33 ("Update net/ to use sg helpers") converted many files to use the scatter gather helpers without ensuring that the necessary headerfile <linux/scatterlist> is included. This happened to work for ia64, powerpc, sparc64 and x86 because they happened to drag in that file via their <asm/dma-mapping.h>. On most of the others this probably broke. Instead of increasing the header file spider web I choose to include <linux/scatterlist.h> directly into the affectes files.

2007-10-14Fix compile while compiling drivers/mmc/host/mmc_spi.o with !BLOCKDavid Brownell1-1/+1
Make sure the mmc_spi driver can build without CONFIG_BLOCK. Issue noted by "Avuton Olrich" <avuton@gmail.com> and randconfig. While that won't be a common configuration, sometimes embedded boards use SDIO to interface WLAN or Bluetooth chips (vs some parallel interface), and don't provide an MMC/SD socket for use with flash memory cards.

2007-10-11mmc: don't use weight32()Nicolas Pitre2-2/+4
Using weight32() to determine if a value is a power of 2 is a rather heavi weight solution. The classic idiom is (x & (x - 1)) == 0, but the kernel already provide a is_power_of_2 function for it. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2007-10-10pxamci: support arbitrary block sizeNicolas Pitre1-3/+16
The PXA has two transmit FIFOes, each32 byte deep. when one FIFO is full and the other one has been transmitted, they are automatically swapped and DMA is triggered for another 32 byte burst. However, when there is less than 32 bytes left to send, the FIFO swap has to be done manually. This is required for some SDIO transfers which are not required to be multiples of 32 bytes. A DMA completion interrupt is set for each descriptor which length isn't a multiple of 32 in order to force the FIFO swap. While at it, the DMA interrupt handler has been made a bit more resilient against errors. Signed-off-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

Thanks to Matt Domsch and Rezwanul Kabir at Dell, we know how to disable the MMC controller on the multi-function Ricoh R5C832.

2007-09-23mmc_spi host driverDavid Brownell3-0/+1422
This is the latest version of the MMC-over-SPI support. It works on 2.6.23-rc2 plus git-mmc (from rc1-mm2), along with the preceding patches which teach the rest of the MMC stack about SPI. The main issue of note is that sometimes cards need to be power cycled to recover after certain faults. Also, it may sometimes be necessary to disable CRCs.

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).
