* mmc: remove multiwrite capabilityPierre Ossman2008-07-151-1/+1
| | | | | | | | | | Relax requirements on host controllers and only require that they do not report a transfer count than is larger than the actual one (i.e. a lower value is okay). This is how many other parts of the kernel behaves so upper layers should already be prepared to handle that scenario. This gives us a performance boost on MMC cards.

* wbsd: fix bad dma_addr_t conversionPierre Ossman2008-07-151-2/+2
| | | | | | | DMA addresses are not pointers, so don't treat them as such. Avoids compiler warnings when using 64-bit DMA addresses on a 32-bit system. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

* mmc: change .get_ro() callback semanticsAnton Vorontsov2008-07-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Now get_ro() callback must return 0/1 values for its logical states, and negative errno values in case of error. If particular host instance doesn't support RO/WP switch, it should return -ENOSYS. This patch changes some hosts in two ways: 1. Now functions should be smart to not return negative values in "RO asserted" case (particularly gpio_ calls could return negative values for the outermost GPIOs). Also, board code usually passes get_ro() callbacks that directly return gpioreg & bit result, so at91_mci, imxmmc, pxamci and mmc_spi's get_ro() handlers need take special care when returning platform's values to the mmc core. 2. In case of host instance didn't implement get_ro() callback, it should really return -ENOSYS and let the mmc core decide what to do about it (mmc core thinks the same way as the hosts, so it isn't functional change).

* mmc: wbsd: initialize tasklets before requesting interruptChuck Ebbert2008-06-131-11/+10
| | | | | | | | | | | | | | | | 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/coldplugKay Sievers2008-04-161-0/+1
| | | | | | | | | | | | | | | 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.
