2015-08-05dmaengine: Add an enum for the dmaengine alignment constraintsMaxime Ripard
Most drivers need to set constraints on the buffer alignment for async tx operations. However, even though it is documented, some drivers either use a defined constant that is not matching what the alignment variable expects (like DMA_BUSWIDTH_* constants) or fill the alignment in bytes instead of power of two. Add a new enum for these alignments that matches what the framework expects, and convert the drivers to it.

2015-04-01dmaengine: ste_dma40: fix implicit conversionStefan Agner
The function d40_prep_sg takes the type enum dma_transfer_direction as second last parameter. However, the memcpy calls pass DMA_NONE which is of type enum dma_data_direction. Fix this by passing the actual transfer direction DMA_MEM_TO_MEM. This does not change the actual code flow since only the transfer direction DMA_MEM_TO_DEV and DMA_DEV_TO_MEM are actually used in the function d40_prep_sg.

2014-12-04PM: Merge the SET*_RUNTIME_PM_OPS() macrosRafael J. Wysocki
The SET_PM_RUNTIME_PM_OPS() and SET_RUNTIME_PM_OPS() macros are identical except that one of them is not empty for CONFIG_PM set, while the other one is not empty for CONFIG_PM_RUNTIME set, respectively. However, after commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is selected) PM_RUNTIME is always set if PM is set, so one of these macros is now redundant. For this reason, replace SET_PM_RUNTIME_PM_OPS() with SET_RUNTIME_PM_OPS() everywhere and redefine the SET_PM_RUNTIME_PM_OPS symbol as SET_RUNTIME_PM_OPS in case new code is starting to use the macro being removed here.
