Subject: [PATCH -next 1/4] dmaengine: xilinx_dma: Fix 64-bit simple AXIDMA transfer
Date: Thu, 26 Sep 2019 16:20:57 +0530 [thread overview]
Message-ID: <1569495060-18117-2-git-send-email-radhey.shyam.pandey@xilinx.com> (raw)
In-Reply-To: <1569495060-18117-1-git-send-email-radhey.shyam.pandey@xilinx.com>
In AXI DMA simple mode also pass MSB bits of source and destination
address to xilinx_write function. It fixes simple AXI DMA operation
mode using 64-bit addressing.
