Hi,
The ti-dma-crossbar driver in it's current form can work when it is used with sDMA (omap-dma). On DRA7x class of devices we have both sDMA and eDMA available. The DT bindings for sDMA has been done in a way that DMA users need to specify the required DMA request number + 1 when they request for channel and the driver stack has been written in this way also for sDMA. Since right now we do not have the crossbar enabled we can still change the compatible string to reflect the crossbar use. The TRM also refers the crossbars in this way.
