mmc: don't use DMA on newer ENE controllers

2008-07-24T16:14:11Z

commit bf5b1935d8e42b36a34645788eb261461fe07f2e upstream. Even the newer ENE controllers have bugs in their DMA engine that make it too dangerous to use. Disable it until someone has figured out under which conditions it corrupts data. This has caused problems at least once, and can be found as bug report 10925 in the kernel bugzilla.

pxamci: fix byte aligned DMA transfers

2008-07-24T16:14:10Z

commit 97f8571e663c808ad2d01a396627235167291556 upstream The pxa27x DMA controller defaults to 64-bit alignment. This caused the SCR reads to fail (and, depending on card type, error out) when card->raw_scr was not aligned on a 8-byte boundary. For performance reasons all scatter-gather addresses passed to pxamci_request should be aligned on 8-byte boundaries, but if this can't be guaranteed, byte aligned DMA transfers in the have to be enabled in the controller to get correct behaviour.

mmc: wbsd: initialize tasklets before requesting interrupt

2008-06-16T20:20:01Z

commit cef33400d0349fb24b6f8b7dea79b66e3144fd8b upstream With CONFIG_DEBUG_SHIRQ set we will get an interrupt as soon as we allocate one. Tasklets may be scheduled in the interrupt handler but they will be initialized after the handler returns, causing a BUG() in kernel/softirq.c when they run.

mmc: fix platform driver hotplug/coldplug

2008-04-16T02:35:40Z

Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable MMC host platform drivers, to re-enable auto loading. Also, add missing owner declarations in driver init.

mmc: extend ricoh_mmc to support Ricoh RL5c476

2008-02-08T08:02:47Z

This patch adds support for the Ricoh RL5c476 chip: with this the mmc adapter that needs this disabler (R5C843) can also be handled correctly when it sits on a RL5c476. Signed-off-by: Frank Seidel Signed-off-by: Pierre Ossman

at91_mci: use generic GPIO calls

2008-02-08T08:02:47Z

Update the AT91 MMC driver to use the generic GPIO calls instead of the AT91-specific calls; and to request (and release) those GPIO signals. That required updating the probe() fault cleanup codepaths. Now there is a single sequence for freeing resources, in reverse order of their allocation. Also that code uses use dev_*() for messaging, and has less abuse of KERN_ERR. Likewise with updating remove() cleanup. This had to free the GPIOs, and while adding that code I noticed and fixed two other problems: it was poking at a workqueue owned by the mmc core; and in one (rare) case would try freeing an IRQ that it didn't allocate.

mmc: remove sdhci and mmc_spi experimental markers

2008-02-08T08:02:46Z

Both of these drivers work well (although some hardware still has its problems) and are not in the "alpha" quality that EXPERIMENTAL suggests. Signed-off-by: Pierre Ossman
