imx6: add support for GW53xx
The Gateworks GW53xx family of products is based on the Freescale i.MX6DL SoC and offers a small form-factor with peripherals such as: * i.MX6DL * NAND FLASH * 4x PCIe * 4x USB EHCI (1x front-panel; 3x PCIe sockets) * 1x USB OTG * 1x uSD * LVDS connector (VLDS for display, PWM/GPIO for backlight, i2c for touch) * HDMI Audio/Video out * Analog Video in * Digital IO * Gateworks System Controller * Accelerometer * Canbus * Optional GPS * Industrial temp (-40C to +85C) * DC input voltage 8 to 42V (Passive PoE and 802.3af) Signed-off-by: Tim Harvey <tharvey@gateworks.com> SVN-Revision: 39012
