Subject: [PATCH 3/4] arm64: dts: meson-axg: add PCIe nodes
Date: Fri, 20 Nov 2020 16:32:28 +0100	[thread overview]
Message-ID: <20201120153229.3920123-4-narmstrong@baylibre.com> (raw)
In-Reply-To: <20201120153229.3920123-1-narmstrong@baylibre.com>

This adds the nodes for the :
- AXG PCIe PHY, using the shared analog PCIe/MIPI DSI PHY
- 2x AXG PCIe controllers
