[PATCH v4] ARM: dts: imx6: Add dts for Embest MarS Board

From: Sergio Prado
Date: Tue Apr 26 2016 - 19:39:13 EST

Embest MarS Board [1] is a multi-core platform based on Freescale i.MX6
Cortex-A9 Dual Core, running up to 1GHz with 1 GB of RAM, 4GB of eMMC
and with a 4MB SPI flash.

Changes v3 -> v4:
- nodes sorted alphabetically in label names
- pinctrl entries sorted alphabetically

Changes v2 -> v3:
- change board compatible string to fsl,imx6q
- the ethernet reset pin is active low
- remove artificial simple-bus for regulators
- add enable-active-high to usb otg vbus regulator node
- remove @1 and @2 from leds node
- remove the unnecessary imx6-riotboard node from iomuxc

Changes v1 -> v2:
- Makefile entry added
