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.

The original device tree binding for this driver, from Viresh Kumar unfortunately conflicted with the generic DMA binding, and did not allow to completely seperate slave device configuration from the controller. This is an attempt to replace it with an implementation of the generic binding, but it is currently completely untested, because I do not have any hardware with this particular controller. The patch applies on top of the slave-dma tree, which contains both the base support for the generic DMA binding, as well as the earlier attempt from Viresh. Both of these are currently not merged upstream however. This version incorporates feedback from Viresh Kumar, Andy Shevchenko and Russell King.

dw_dmac driver already supports device tree but it used to have its platform data passed the non-DT way. This patch does following changes: - pass platform data via DT, non-DT way still takes precedence if both are used. - create generic filter routine - Earlier slave information was made available by slave specific filter routines in chan->private field. Now, this information would be passed from within dmac DT node. Slave drivers would now be required to pass bus_id (a string) as parameter to this generic filter(), which would be compared against the slave data passed from DT, by the generic filter routine. - Update binding document Signed-off-by: NViresh Kumar <viresh.kumar@linaro.org> Reviewed-by: NAndy Shevchenko <andriy.shevchenko@linux.intel.com> [Fixed __devinit usage] Signed-off-by: NVinod Koul <vinod.koul@linux.intel.com>

SPEAr platforms now support DT and so must convert all drivers to support DT. This patch adds DT probing support for Synopsys DMA controller and updates its documentation too. Signed-off-by: NViresh Kumar <viresh.kumar@st.com> Signed-off-by: NVinod Koul <vinod.koul@linux.intel.com>
