Subject: [PATCH 5/6] arm64: dts: meson-g12a: Add PCIe node
Date: Sun,  8 Sep 2019 13:42:57 +0000	[thread overview]
Message-ID: <1567950178-4466-6-git-send-email-narmstrong@baylibre.com> (raw)
In-Reply-To: <1567950178-4466-1-git-send-email-narmstrong@baylibre.com>

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 differentil lines are used for PCIe instead of USB3.
