[PATCH v4 1/5] dmaengine: vdma: Rename xilinx_vdma_ prefix to xilinx_dma

Kedareswara rao Appana appana.durga.rao at xilinx.com
Wed Apr 6 22:29:41 PDT 2016


This patch renames the xilinx_vdma_ prefix to xilinx_dma
for the API's and masks that will be shared b/w three DMA
IP cores.

Signed-off-by: Kedareswara rao Appana <appanad at xilinx.com>
---
Changes for v4:
----> Removed renaming of vdma-mm2s/vdma-s2mm channel names.
Changes for v3:
---> None.
Changes for v2:
---> New patch as suggested by Laurent Pinchart.
