Subject: [PATCH v2 10/11] arm64: dts: fast models: Enable PCIe ATS for Base RevC FVP
Date: Wed, 11 Mar 2020 13:45:05 +0100 [thread overview]
Message-ID: <20200311124506.208376-11-jean-philippe@linaro.org> (raw)
In-Reply-To: <20200311124506.208376-1-jean-philippe@linaro.org>
Declare that the host controller supports ATS, so the OS can enable it
for ATS-capable PCIe endpoints.
