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.
