Subject: [PATCH v2 3/3] arm64: dts: fvp: Enable PCIe ATS for Base RevC FVP
Date: Fri,  7 Jun 2024 11:54:16 +0100	[thread overview]
Message-ID: <20240607105415.2501934-5-jean-philippe@linaro.org> (raw)
In-Reply-To: <20240607105415.2501934-2-jean-philippe@linaro.org>

Declare that the host controller supports ATS, so the OS can enable it
for ATS-capable PCIe endpoints.
