[PATCH 1/2] dt-bindings: dmaengine: xilinx_dma: Add VDMA vertical flip property

From: Radhey Shyam Pandey
Date: Wed Jun 13 2018 - 03:35:41 EST

The AXI VDMA core supports Vertical flip in S2MM path when Enable
Vertical Flip (Advanced tab) is selected. To allow vertical flip
programming define an optional 'xlnx,enable-vert-flip' channel
child node property.
