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. Signed-off-by: Stefan Wahren <stefan.wahren@i2se.com>
