Subject: [PATCH v2 6/6] arm64: apple: Add PCIe node
From: Mark Kettenis <kettenis@...nbsd.org>
Add node corresponding to the apcie,t8103 node in the Apple device tree
for the Mac mini (M1, 2020).
Clock references are left out at the moment and will be added once the
appropriate bindings have been settled on.
