From 7cbb0c63de3fc218fd06ecfedb477772a4d12f76 Mon Sep 17 00:00:00 2001 From: Hyun Kwon Date: Fri, 17 Jul 2020 04:33:35 +0300 Subject: dmaengine: xilinx: dpdma: Add the Xilinx DisplayPort DMA engine driver The ZynqMP DisplayPort subsystem includes a DMA engine called DPDMA with 6 DMa channels (4 for display and 2 for audio). This driver exposes the DPDMA through the dmaengine API, to be used by audio (ALSA) and display (DRM) drivers for the DisplayPort subsystem.
