ARM: dmabounce: get rid of dma_needs_bounce global function

2011-07-04T07:39:55Z

Pass the device type specific needs_bounce function in at dmabounce register time, avoiding the need for a platform specific global function to do this. Signed-off-by: Russell King

ARM: dmabounce: correct unmap_single dev_dbg

2011-07-03T22:56:17Z

DMA addresses should not be casted to void * for printing. Fix that to be consistent with the rest of the file. Signed-off-by: Russell King

ARM: dmabounce: check pointer against NULL not 0

2011-07-03T22:54:34Z

Pointers should be checked against NULL rather than 0, otherwise we get sparse warnings. Signed-off-by: Russell King

ARM: dmabounce: remove useless pr_err

2011-07-03T22:53:13Z

We already check that dev != NULL, so this won't be reached. Signed-off-by: Russell King

ARM: dmabounce: move decision for bouncing into __dma_map_page()

2011-07-03T22:28:31Z

Move the decision whether to bounce into __dma_map_page(), before the check for high pages. This avoids triggering the high page check for devices which aren't using dmabounce. Fix the unmap path to cope too. Signed-off-by: Russell King

ARM: dmabounce: separate out decision to bounce

2011-07-03T22:27:49Z

Move the decision to perform DMA bouncing out of map_single() into its own stand-alone function. Signed-off-by: Russell King

ARM: dmabounce: avoid needless valid_dma_direction() check

2011-07-03T22:27:49Z

This check is done at the DMA API level, so there's no point repeating it here. Signed-off-by: Russell King

ARM: dma-mapping: define dma_(un)?map_single in terms of dma_(un)?map_page

2011-07-03T22:27:49Z

Use dma_map_page()/dma_unmap_page() internals to handle dma_map_single() and dma_unmap_single(). Signed-off-by: Russell King

ARM: dmabounce: fix map_single() error return value

2011-07-03T22:24:21Z

When map_single() is unable to obtain a safe buffer, we must return the dma_addr_t error value, which is ~0 rather than 0. Signed-off-by: Russell King

ARM: DMA: add support for DMA debugging

2011-01-06T22:31:11Z

Add ARM support for the DMA debug infrastructure, which allows the DMA API usage to be debugged. Signed-off-by: Russell King
