Hi,
Changes since v01: - Drop change in compatible for the crossbar driver and do the configuration based on the DT structure.
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 sDMA driver expects to get the DMA request line with offset 1. The eDMA stack does not need the offset. The crosbbar itself is identical for sDMA and eDMA. At probe time the driver will do a match to figure out which dma engine it is connected to and based on that information it will configure the offset needed by the DMA driver.
