This patch adds support for the Variscite VAR_SOM-MX6 SoM with :
- i.MX6 Quad or Dual Lite SoC
- 256 – 4096 MB DDR3
- 4-64 GB eMMC
- 128 – 1024 MB SLC NAND
- Camera Interface
- HDMI+CEC interface
- LVDS / DSI / Parallel RGB interfaces
- Ethernet RGMII interface
- On-SoM Wi-Fi/Bluetooth with WiLink wl183x SDIO Module
- SD/MMC/SDIO interface
- USB Host + USB OTG interface
- I2C interfaces
- SPI interfaces
- PCI-Express 2.0 interface
- on-SoM Audio Codec with HP/Line-In interfaces + DMIC interface
- Digital Audio interface
- S/PDIF interface
Product website : https://www.variscite.com/product/system-on-module-som/cortex-a9/var-som-mx6-cpu-freescale-imx6/
Support is handled with a SoM-centric dtsi exporting the default interfaces
along the default pinmuxing to be enabled by the board dts file.
This file is based on the one provided by Variscite on their own
kernel, but adapted for mainline.

This patch adds support for the Variscite 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
- S-ATA
- On-board DMIC
- RS485 Header
- CAN bus header
- SPI header
- Camera Interfaces header
- OnBoard RTC with Coin Backup battery socket
- RS232 Debug Header (IDC10)
- RS232 DTE
Product Page : https://www.variscite.com/product/single-board-computers/var-mx6customboard
The dts file based on the ones provided by Variscite on their own
kernel, but adapted for mainline.
