[v3,09/10] ARM: dts: imx6ul: support Engicam MicroGEA GTW board
Commit Message
Support Engicam MicroGEA GTW board with:
- 256 Mbytes NAND Flash
- 512 Mbytes DRAM DDR2
- Buttons
- LEDs
- Micro SD card connector
- USB 2.0 high-speed/full-speed
- Ethernet MAC

Changes in v3:
- Drop an extra blank line from the iomuxc node.
Changes in v2:
- Drop an extra blank line
- Move iomuxc and iomuxc_snvs nodes to the end of the DTS file.
