Subject: [PATCH 1/2] dt-bindings: dmaengine: xilinx_dma: Add VDMA vertical flip property
Date: Wed, 13 Jun 2018 13:04:47 +0530 [thread overview]
Message-ID: <1528875288-9140-2-git-send-email-radhey.shyam.pandey@xilinx.com> (raw)
In-Reply-To: <1528875288-9140-1-git-send-email-radhey.shyam.pandey@xilinx.com>
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.
