Subject: [PATCH v3 2/5] arm64: dts: ti: k3-am64-main: Add PCIe DT node
Date: Wed, 26 May 2021 19:59:18 +0530 [thread overview]
Message-ID: <20210526142921.12127-3-kishon@ti.com> (raw)
In-Reply-To: <20210526142921.12127-1-kishon@ti.com>
AM64 has one PCIe instance which can be configured in either
host mode (RC) or device mode (EP). Add PCIe DT node for host
mode and device mode here.
