Commit 6584cb88 (ARM i.MX dma: Fix burstsize settings) fixed the mxcmmc driver but forgot to fix the SDMA driver to handle the correct burtsize. This make the SD card access works again with DMA on i.MX31 boards.

commit 46389470 deleted redundant chan_id and chancnt initialization in dma drivers as this is done in dma_async_device_register(). However, atc_enable_irq() relied on chan_id set before registering the device, what left only channel 0 functional for this driver. This patch introduces atc_enable/disable_chan_irq() as a variant of atc_enable/disable_irq() with the channel as explicit argument.

We don't need extra lock, so we use non-atomic bit ops to set/clear bits, merge event_mask0 and event_mask1 into an array, it helps use bit ops. It also fixs the issue: sdmac->event_mask0 = 1 << sdmac->event_id0; sdmac->event_mask1 = 1 << (sdmac->event_id0 - 32); It event_id0 < 32, it shifts negative number. If event_id0 >= 32, it shifts number >= sizeof(int). Both the cases behavior is undefined.

Hi, On the latest tree my compiler has started giving the warning: drivers/dma/dmatest.c:575:28: warning: the omitted middle operand in ?: will always be ?true?, suggest explicit middle operand [-Wparentheses] The following patch fixes the missing middle clause with the same fix that Nicolas Ferre used in the similar clauses. (There seems to have been a race between him fixing that and the extra clause going in a little later). I don't actually know the dmatest code/structures, nor do I own any hardware to test it on (assuming it needs a DMA engine); but this patch builds, the existing code is almost certainly wrong and the fix is the same as the corresponding lines above it. (WTH is x=y?:z legal C anyway?)
