From 34e658087e54db26ebd86f86a1549a393002a9ad Mon Sep 17 00:00:00 2001
From: Phil Elwell <phil@raspberrypi.com>
Date: Fri, 26 Nov 2021 15:20:06 +0000
Subject: [PATCH] ARM: dts: Update rpi-400 and cm4 dts to match 4-b
The Pi 4B dts file has had numerous updates since the Pi 400 and CM4
dts files were written. Apply those updates to the other files to
minimise the differences. The change is largely cosmetic, except for
the PCI "device-type" to "device_type" rename, and the correction of
the labels on the Pi 400 GPIO expander pins.
