[PATCH 1/8] ARM: dts: imx7d-sbc-iot: add initial iot gateway dts

[tyler-yzvPICuk2AAEdKtRPRuaE5USO3DlRtUf@public.gmane.org]

From: Tyler Baker <tyler-yzvPICuk2AAEdKtRPRuaE5USO3DlRtUf@public.gmane.org>

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.
