+Subject: arm64: dts: Add support for Raspberry Pi Compute Module 4 IO Board
+
+It was introduced in mainline during the v5.16 release cycle. Since
+many broadcom includes were reworked since v5.10, adding support would
+involve more than cherry-picking a DTS addition that uses a few
+includes.
+
+To avoid side effects on other models, introduce a DTS that leverages
+some existing includes (bcm2711.dtsi and bcm283x-rpi-usb-host.dtsi)
+and describes the rest without re-using parts of the Raspberry Pi 4 B
+model.
+
+To avoid phandle rotation (0x16, 0x17, and 0x18) across 3 nodes
+(dma@7e007000, i2c@7e205000, and interrupt-controller@7ef00100), and the
+related changes in other nodes referencing them, hardcode 0x16 as the
+phandle for interrupt-controller@7ef00100. This leads to an empty dtdiff
+between this new DTB and the one produced by a v5.16-rc8 build.
