2013-08-14dma: mmp_pdma: add filter functionDaniel Mack
PXA peripherals need to obtain specific DMA request ids which will eventually be stored in the DRCMR register. Currently, clients are expected to store that number inside the slave config block as slave_id, which is unfortunately incompatible with the way DMA resources are handled in DT environments. This patch adds a filter function which stores the filter parameter passed in by of-dma.c into the channel's drcmr register. For backward compatability, cfg->slave_id is still used if set to a non-zero value.

2012-10-15dma: ipu: rename mach/ipu.h to include/linux/dma/ipu-dma.hShawn Guo
The header ipu.h really belongs to dma subsystem rather than imx platform. Rename it to ipu-dma.h and put it into include/linux/dma/.
