2007-02-04mmc: sdhci: replace kmap with page_addressPierre Ossman
Since we actively avoid highmem, calling kmap_atomic() instead of page_address() is effectively only obfuscation. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2007-02-04mmc: Allow host drivers to specify a max block sizePierre Ossman
Most controllers have an upper limit on the block size. Allow the host drivers to specify this and make sure we avoid hitting this limit. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2006-12-01mmc: sdhci high speed supportPierre Ossman
The SDHCI spec implies that is is incorrect to set a clock frequency above 25 MHz without setting the high speed bit. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2006-10-01[PATCH] mmc (mainly): add "or later" clause to licence statement.Pierre Ossman
Clarify my (Pierre's) position on which GPL versions apply. The patch only touches the source files where I am the only major author. The people who have made the minor commits to the files have been contacted and have no issues with this change.

2006-07-02[MMC] sdhci: support controller specific quirksPierre Ossman
As some specific controllers will have bugs, we need a way to map special behaviour to certain hardware. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-07-02[MMC] sdhci: more DMA capabilities testsPierre Ossman
Properly test for controller interface to see if it's DMA capable. As many controllers are misconfigured in this regard, also add debug parameters to force DMA support either way.

2006-07-02[MMC] sdhci: check controller versionPierre Ossman
Check the interface version of the controller and bail out if it's an unknown version. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-07-02[MMC] sdhci: Test for invalid block sizePierre Ossman
The controller has an upper limit on the block size. Make sure we do not cross it. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-07-02[MMC] sdhci: Avoid sdhci DMA boundariesPierre Ossman
The sdhci controllers will issue an interrupt when a configurable number of bytes have been transfered using DMA. The purpose is to handle multiple, scattered memory pages. Unfortunately, it requires that all transfers are completely aligned to memory pages, which we cannot guarantee. So we just disable the function.

2006-07-02[MMC] Fix sdhci PIO routinesPierre Ossman
The sdhci controllers operate with blocks, not bytes. The PIO routines must therefore make sure that the minimum unit transfered is a complete block. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-07-02[MMC] sdhci: proper timeout handlingPierre Ossman
Use the give timeout clock and calculate a proper timeout instead of using the maximum at all times. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-07-02[MMC] sdhci: support for multiple voltagesPierre Ossman
The sdhci controllers can support up to three voltage levels. Detect which and report back to the MMC layer. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-03-24[PATCH] mmc: Secure Digital Host Controller Interface driverPierre Ossman
Driver for the Secure Digital Host Controller Interface specification. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx> Cc: Russell King <rmk@arm.linux.org.uk> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
