Subject: [PATCH net-next v4 1/6] dt-bindings: net: tsnep: Allow dma-coherent
Date: Tue, 27 Sep 2022 21:58:37 +0200 [thread overview]
Message-ID: <20220927195842.44641-2-gerhard@engleder-embedded.com> (raw)
In-Reply-To: <20220927195842.44641-1-gerhard@engleder-embedded.com>
Within SoCs like ZynqMP, FPGA logic can be connected to different kinds
of AXI master ports. Also cache coherent AXI master ports are available.
The property "dma-coherent" is used to signal that DMA is cache
coherent.
Add "dma-coherent" property to allow the configuration of cache coherent
DMA.
