+Subject: ARM: dts: add Raspberry Pi Compute Module 3 and IO board
+Origin: https://git.kernel.org/linus/a54fe8a6cf66828499b121c3c39c194b43b8ed94
+
+The Raspberry Pi Compute Module 3 (CM3) and the Raspberry Pi
+Compute Module 3 Lite (CM3L) are SoMs which contains a BCM2837 processor,
+1 GB RAM and a GPIO expander. The CM3 has a 4 GB eMMC, but on the CM3L
+the eMMC is unpopulated and it's up to the user to connect their
+own SD/MMC device. The dtsi file is designed to work for both modules.
+There is also a matching carrier board which is called
+Compute Module IO Board V3.
