From: Tyler Baker <[email protected]> The Compulab IoT Gateway is based on an NXP i.MX7D, dual core Cortex-A7 clocking at 1GHz. It supports up to 2GB of DDR3, and 32GB of eMMC flash. Onboard, there are two gigabit ethernet controllers, 4 x USB2, RS485, and CAN.
This platform is based on the imx7d-cl-som-imx7 module but includes a baseboard with additional peripherals which is what this device tree is meant to describe. This work has been derrived from the Compulab Linux sources based on v4.1.
