Subject: [PATCH 1/2] arm64: dts: meson-axg: add PCIe nodes
Date: Wed,  7 Oct 2020 12:06:30 +0200	[thread overview]
Message-ID: <20201007100631.192348-2-narmstrong@baylibre.com> (raw)
In-Reply-To: <20201007100631.192348-1-narmstrong@baylibre.com>

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