    Subject[PATCH 1/3] ARM: dts: imx6: Add Savageboard common file
    Date
    This patch enables common board DT properties for Poslab i.MX6 Savageboard
    dual and quad. (https://www.savageboard.org)

    * Memory
    memblock for DDR3 1GB

    * Regulator
    3.3V for panel and backlight.

    * Display
    Enable HDMI and LVDS panel. Savageboard supports AVIC TM097TDH02 panel
    which is compatible with Hannstar HSD100PXN1, so reuse it.

    * Clock
    The commit d28be499c45e6 is applied to support LVDS and HDMI output
    simultaneously.

    * Pinmux
    eMMC, ethernet, HDMI, I2C, power button, PWM, SD card and UART.

    * Others
    Enable ethernet, UART1 debug, USB host, USDHC3 for microSD card and
    USDHC4 for built-in eMMC storage.
