Date: Mon, 5 Oct 2020 15:46:39 +0300 From: Madalin Bucur <madalin.bucur@....nxp.com> To: shawnguo@...nel.org Cc: devicetree@...r.kernel.org, leoyang.li@....com, robh+dt@...nel.org, linux-arm-kernel@...ts.infradead.org, netdev@...r.kernel.org, camelia.groza@....nxp.com, Madalin Bucur <madalin.bucur@....nxp.com> Subject: [PATCH] arm64: dts: fsl: DPAA FMan DMA operations are coherent Although the DPAA 1 FMan operations are coherent, the device tree node for the FMan does not indicate that, resulting in a needless loss of performance. Adding the missing dma-coherent property.
