Add support for i.MX6UL modules from Kontron Electronics GmbH (before
acquisition: Exceet Electronics) and evalkit boards based on it:
1. N6310 SOM: i.MX6 UL System-on-Module, a 25x25 mm solderable module
(LGA pads and pin castellations) with 256 MB RAM, 1 MB NOR-Flash,
256 MB NAND and other interfaces,
2. N6310 S: evalkit, w/wo eMMC, without display,
3. N6310 S 43: evalkit with 4.3" display,
4. N6310 S 50: evalkit with 5.0" display.
This includes device nodes for unsupported displays (Admatec
T043C004800272T2A and T070P133T0S301).
The work is based on Exceet/Kontron source code (GPLv2) with numerous
changes:
1. Reorganize files,
2. Rename Exceet -> Kontron,
3. Rename models/compatibles to match newest Kontron product naming,
4. Fix coding style errors and adjust to device tree coding guidelines,
5. Fix DTC warnings,
6. Extend compatibles so eval boards inherit the SoM compatible,
7. Use defines instead of GPIO and interrupt flag values,
8. Use proper vendor compatible for Macronix SPI NOR,
9. Sort nodes alphabetically.

Changes since v2, after Fabio's review:
1. Add "imx6ul" compatible to board name (that's what I understood from
review),
2. Add vendor/device prefix to eeprom and document the compatible,
3. Use "admatecde" as vendor compatible to avoid confusion with Admatec
AG in Switzerland (also making LCD panels),
4. Use generic names for nodes,
5. Use IRQ_TYPE_LEVEL_LOW,
6. Move iomux to the end of files,
7. Remove regulators node (include regulators in top level),
8. Remove cpu clock-frequency,
9. Other minor fixes pointed by Fabio.
Changes since v1, after Frieder's review:
1. Remove unneeded license notes,
2. Add Kontron copyright (2018),
3. Rename the files/models/compatibles to new naming - N6310,
4. Remove unneeded CPU operating points override,
5. Switch regulator nodes into simple children nodes without addresses
(so not simple bus),
6. Use proper vendor compatible for Macronix SPI NOR.
