Subject: [PATCH v2 2/2] arm64: apple: Add PCIe node
Date: Mon, 31 May 2021 00:44:01 +0200	[thread overview]
Message-ID: <20210530224404.95917-3-mark.kettenis@xs4all.nl> (raw)
In-Reply-To: <20210530224404.95917-1-mark.kettenis@xs4all.nl>

From: Mark Kettenis <kettenis@openbsd.org>

Add node corresponding to the apcie,t8103 node in the
Apple device tree for the Mac mini (M1, 2020).

Clock references and DART (IOMMU) references are left out at the
moment and will be added once the appropriate bindings have been
settled upon.
