This patch adds support for the Variscite DART-MX6 SoM with : - i.MX6 Quad or Dual Lite SoC - 1Gb/2Gb LPDDR2 - 4-64 GB eMMC - Camera Interface - HDMI+CEC interface - LVDS / DSI / Parallel RGB interfaces - Ethernet RGMII interface - On-SoM Wi-Fi/Bluetooth with WiLink wl1835 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 : http://www.variscite.com/products/system-on-module-som/cortex-a9/dart-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. Only board-independent devices like WiFi, eMMC or PMIC are enabled in the dtsi.
