[PATCH v1 0/6] ARM: dts: introduce Compulab IoT Gateway

[tyler at opensourcefoundries.com]

From: Tyler Baker <tyler@opensourcefoundries.com>

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.

Changes for v1 (Requested by Fabio)
  * Squashed the dts build into the initial patch
  * Dropped the phy refclk patch from this series, submitting to PCI list
  * Removed fsl,spi-num-chipselects property
  * Removed LCD and DVI nodes, will follow up with a later series
  * s/fsl,uart-has-rtscts/uart-has-rtscts/g
  * Fixed regulator usage inside of simple-bus

The entire series is based on v4.15-rc2.

and 32GB of eMMC flash. Onboard, there are two gigabit

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.

Looks like the I2C2 fix should be a separate patch.
