2014-10-15	dmaengine: dw: export probe()/remove() and Co to users	Andy Shevchenko	1	-0/+27
	The driver library functions can be used directly by the compound devices such as ADSP or serial driver where DesignWare DMA IP is privately attached to the main hardware. Instead of creating a new platform device leaf they may call dw_dma_probe() with given struct dw_dma_chip directly and make sure that the main device is DMA capable.

2014-10-15	dmaengine: dw: split dma-dw.h to platform and private parts	Andy Shevchenko	1	-0/+37
	The introduced include/linux/dma/dw.h is going to contain the private extensions and structures which are shared for dw_dmac users in the kernel. Meanwhile include/linux/platform_data/dma-dw.h keeps only platform related data types and definitions.

2013-08-14	dma: mmp_pdma: add filter function	Daniel Mack	1	-0/+15
	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.

2012-10-15	dma: ipu: rename mach/ipu.h to include/linux/dma/ipu-dma.h	Shawn Guo	1	-0/+177
	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/.
