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.
It uses the same SoM as the cl-som-imx7, but includes a baseboard
with additional I/O.
Compulab has provided patches for this platform based on v4.1.
I've used these patches as reference to get things working on tip.
The entire series is based on v4.15-rc1.

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.

In the i.MX7D the PCIe PHY can use either externel oscillator or
internal PLL as a reference clock source.
Add support for the PHY Reference Clock source including
device tree property phy-ref-clk.
External oscillator is used as a default reference clock source.

As you are adding a new property you should update
