ARM: dts: imx6q: Add Variscite DART-MX6 Carrier-board support
This patch adds support for the i.MX6 Quad variant of the Variscite DART-MX6 SoM Carrier-Board. This Carrier-Board has the following : - LVDS interface for the VLCD-CAP-GLD-LVDS 7" LCD 800 x 480 touch display - HDMI Connector - USB Host + USB OTG Connector - 10/100/1000 Mbps Ethernet - miniPCI-Express slot - SD Card connector - Audio Headphone/Line In jack connectors - On-board DMIC - CAN bus header - SPI header - Camera Interfaces header - 4xButtons, 2xLeds - OnBoard RTC with Coin Backup battery socket - RS232 Header + USB-Serial debug port Product Page : http://www.variscite.com/products/evaluation-kits/dart-mx6-kits The board support is done with all on-board and header interfaces enabled. 7" LVDS Touchscreen is enabled by default along HDMI output. Audio interface is supported with the "simple-card" bindings. PCIe slot, On-Board DMIC and Camera Interfaces are not handled yet.
