2015-02-04dmaengine: dw: define DW_DMA_MAX_NR_MASTERSAndy Shevchenko1-1/+3
Instead of using magic number in the code the patch provides DW_DMA_MAX_NR_MASTERS constant. While here, restrict the reading of data width array by amount of the actual number of AHB masters. Signed-off-by: Andy Shevchenko <[email protected]> Signed-off-by: Vinod Koul <[email protected]>
2015-02-04dmaengine: dw: amend description of dma_dev fieldAndy Shevchenko1-1/+1
The dma_dev field is widely used in filter functions to mach with a proper DMA controller device. Thus it's not deprecated. The patch fixes the description of that field. There is no functional change. Signed-off-by: Andy Shevchenko <[email protected]> Signed-off-by: Vinod Koul <[email protected]>
2014-10-15dmaengine: dw: split dma-dw.h to platform and private partsAndy Shevchenko1-23/+4
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. Signed-off-by: Andy Shevchenko <[email protected]> Signed-off-by: Vinod Koul <[email protected]>
2014-10-15dmaengine: dw: move private definitions to regs.hAndy Shevchenko1-31/+0
Since we don't allow user to set registers directly through private slave configuration we may move definitions to the regs.h because they are not used anywhere except core.c part. Signed-off-by: Andy Shevchenko <[email protected]> Signed-off-by: Vinod Koul <[email protected]>
2014-09-11dmaengine: dw: convert dw_dma_slave to use explicit HS interfacesAndy Shevchenko1-6/+4
Instead of exposing the possibility to set DMA registers CFG_HI and CFG_LO strict user to provide handshake interfaces explicitly. Signed-off-by: Andy Shevchenko <[email protected]> Acked-by: Hans-Christian Egtvedt <[email protected]> Signed-off-by: Vinod Koul <[email protected]>
2014-09-11dmaengine: dw: move dw_dmac.h to where it belongs toAndy Shevchenko1-0/+111
There is a common storage for platform data related structures and definitions inside kernel source tree. The patch moves file from include/linux to include/linux/platform_data and renames it acoordingly. The users are also updated.
