Subject: [PATCH] arm64: dts: fsl: DPAA FMan DMA operations are coherent
Date: Mon,  5 Oct 2020 15:46:39 +0300	[thread overview]
Message-ID: <1601901999-28280-1-git-send-email-madalin.bucur@oss.nxp.com> (raw)

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.

Fixes: 1ffbecdd8321 ("arm64: dts: add DPAA FMan nodes")
