[PATCH v3 1/2] dmaengine: vdma: Add 64 bit addressing support for the axi dma

2016-06-07 Thread Kedareswara rao Appana
The AXI DMA is a soft ip, which can be programmed to support 32 bit addressing or greater than 32 bit addressing. When the AXI DMA ip is configured for 32 bit address space in simple dma mode the buffer address is specified by a single register (18h for MM2S channel and 48h for S2MM channel).
