From 3dfef536103d61b4a2b98a248af236aa9bf05e45 Mon Sep 17 00:00:00 2001 From: Mark Kettenis Date: Sat, 23 Oct 2021 16:58:06 +0200 Subject: arm: dts: apple: Add preliminary device trees Add preliminary device trees for the Apple M1 mini (2020) and Apple M1 Macbook Pro 13" (2020). Device tree bindings for the Apple M1 SoC are still being formalized and these device trees will be synchronized with the Linux kernel as needed. The device trees in this commit are based on the initial Apple M1 device trees from Linux 5.13, nodes for dart, pcie, pinctrl, pmgr, usb based on bindings on track for inclusion in Linux 5.15 and 5.16 and nodes for i2c, mailbox, nvme, pmu, spmi and watchdog that don't have a proposed binding yet. These device trees are provided as a reference only as U-Boot uses the device tree passed by the m1n1 bootloader.
