Subject: [PATCH 1/2] ARM: dts: imx6ul: Add DTS for liteSOM module

This is a SOM (System on Module), so it will be part of another boards.
|

Hence, this is a "dtsi" file that will be included from another device
|
|
tree files.
|
|
|
|
Hardware specification:
|
|
* Freescale i.MX6UL SoC
|
|
* up to 512 MB RAM
|
|
* eMMC on uSDHC2
