Subject: [PATCH 4.14 079/148] arm64: dts: ls1043a: FMan erratum A050385

From: Madalin Bucur <madalin.bucur@....com>

[ Upstream commit b54d3900862374e1bb2846e6b39d79c896c0b200 ]

The LS1043A SoC is affected by the A050385 erratum stating that
FMAN DMA read or writes under heavy traffic load may cause FMAN
internal resource leak thus stopping further packet processing.
