2006-08-07[MMC] Another stray 'io' referencePierre Ossman
Another misuse of the global 'io' variable instead of the local 'base'. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-08-06[MMC] Fix base address configuration in wbsdPierre Ossman
There were some confusion about base I/O variables in the wbsd driver. Seems like things have been working on shear luck so far. The global 'io' variable (used when manually configuring the resources) was used instead of the local 'base' variable.

2006-08-06[ARM] 3744/1: MMC: mmcqd gets stuck when block queue is pluggedJuha [êölä
Patch from Juha [êölä When the block queue is plugged, mq->req must be set to NULL. Otherwise mq->req might be left non-NULL, even though mmcqd is not processing a request, thus preventing the MMC queue thread from being woken up when new requests do arrive.

2006-07-13[MMC] Change SDHCI version error to a warningPierre Ossman
O2 Micro's controllers have a larger specification version value and are therefore denied by the driver. When bypassing this check they seem to work fine. This patch makes the code a bit more forgiving by changing the error to a warning. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2006-07-03[PATCH] lockdep: annotate on-stack completions, mmcIngo Molnar
lockdep needs to have the waitqueue lock initialized for on-stack waitqueues implicitly initialized by DECLARE_COMPLETION(). Annotate mmc_wait_for_req()'s on-stack completion accordingly. Has no effect on non-lockdep kernels.

2006-07-02[MMC] sdhci: remove duplicate error messagePierre Ossman

2006-07-02[MMC] sdhci: support controller specific quirksPierre Ossman

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: reset sdhci controller earlyPierre Ossman

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. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
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: fix interrupt handlingPierre Ossman
The specification says that interrupts should be cleared before the source is removed. We should also not set unknown bits. 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: fix sdhci reset timeoutPierre Ossman
The reset register is automatically cleared when the reset has completed. Hence, we should busy wait and not have a fixed delay. 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: fix timeout loops in sdhciPierre Ossman
The current timeout loop assume that jiffies are updated. This might not be the case depending on locks and if the kernel is compiled without preemption. Change the system to use a counter and fixed delays.

2006-07-02[MMC] sdhci: support for multiple voltagesPierre Ossman

2006-07-02[MMC] sdhci: print device idPierre Ossman
As sdhci is a generic driver, it is helpful to see some more specific identification of the actual hardware in dmesg. PCI vendor, device and revision is sufficient in most cases.

2006-07-02[MMC] sdhci: check SDHCI base clockPierre Ossman
A base clock value of 0 means that the driver must get the base clock through some other means. As we have no other way of getting it, we must abort.

2006-06-19[ARM] 3565/1: AT91RM9200 MMC updateAndrew Victor
Patch from Andrew Victor This patch includes code cleanups and minor fixes to the AT91RM9200 MMC driver. 1. Replace calls to DBG() with pr_debug(). 2. 'host' can never be null, so don't bother checking for that case. 3. Remove SA_SAMPLE_RANDOM from request_irq(). [Patch from Matt Mackall] 4. clk_get() doesn't return NULL on error - need to test returned value with IS_ERR(). 5. Free resources if clk_get() or request_irq() fails.

2006-06-19[MMC] Convert all hosts except mmci to use data->blkszRussell King
The MMC specification allows non-power of two block sizes. As such, we should not pass the log2 block size to host drivers, but instead pass the byte size. However, ARM MMCI can only work with log2 block size, so continue to pass both the log2 block size and byte block size. This means that for the moment, the byte block size must remain a power of two, but this is the first stage of removing this restriction for other hosts.

2006-05-04[MMC] Move set_ios debugging into mmc.cRussell King
Rather than having every driver duplicate the set_ios debugging, provide a single version in mmc.c which can be expanded as we add additional functionality. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-05-04[MMC] Correct mmc_request_done commentsRussell King
mmc_request_done should be called at the end of handling a request, not between the data and initial command parts of the request. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-05-02[MMC] PXA: reduce the number of lines PXAMCI debug usesRussell King
There's no reason for the PXAMCI debug code to print so many lines - it causes the kernel buffer to overflow when trying to debug this driver. Remove some debug messages which are duplicated by core code, and combine other messages, resulting in fewer characters written to the kernel log.

2006-05-02[MMC] PXA and i.MX: don't avoid sending stop command on errorRussell King
Always send a stop command at the end of a data transfer. If we avoid sending the stop command, some cards remain in data transfer mode, and refuse to accept further read/write commands. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-05-02[MMC] extend data timeout for writesRussell King
The CSD contains a "read2write factor" which determines the multiplier to be applied to the read timeout to obtain the write timeout. We were ignoring this parameter, resulting in the possibility for writes being timed out too early. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
