This patchset adds a device tree include for the ConnectCore 6UL
System-On-Module and a device tree for the ConnectCore 6UL SBC Express board
that includes it.
Not all the SOM hardware is supported in this initial patchset, specifically
the 802.11 WiFi and BT chipset and the extended functionality provided by
the on module NXP Kinetis KL03 are not supported.
The SOM is based on NXP's i.MX6UL SoC, and the patchset is tested against
v4.18-rc4.
More information about the hardware can be found at:
ConnectCore 6UL SOM:
https://www.digi.com/products/embedded-systems/system-on-modules/connectcore-for-i-mx6ul
ConnectCore 6UL SBC Express board:
https://www.digi.com/products/embedded-systems/single-board-computers/connectcore-for-i-mx6ul-sbc-express
Changes since v1 [1]:
* Remove not needed DT properties
* Formatting changes:
* Re-order nodes alphabetically
* Add empty lines between properties and child nodes
* Use generic node names
