From 934de3415e5e63561530d1c571dc47e116a9c63a Mon Sep 17 00:00:00 2001 From: Neil Armstrong Date: Mon, 16 Sep 2019 14:50:21 +0200 Subject: [PATCH] arm64: dts: meson-g12a: Add PCIe node This adds the Amlogic G12A PCI Express controller node, also using the USB3+PCIe Combo PHY. The PHY mode selection is static, thus the USB3+PCIe Combo PHY phandle would need to be removed from the USB control node if the shared differential lines are used for PCIe instead of USB3.
