Subject: [PATCH v5 3/3] arm64: dts: qcom: sa8775p: Mark PCIe EP controller as cache coherent
Date: Fri, 23 Feb 2024 19:33:40 +0530	[thread overview]
Message-ID: <1708697021-16877-4-git-send-email-quic_msarkar@quicinc.com> (raw)
In-Reply-To: <1708697021-16877-1-git-send-email-quic_msarkar@quicinc.com>

The PCIe EP controller on SA8775P supports cache coherency, hence add
the "dma-coherent" property to mark it as such.
