* 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 d28be499c4 ("ARM: dts: imx6qdl-sabresd: Allow HDMI and
LVDS to work simultaneously") is applied to support LVDS and HDMI output
at the same time.
* Pinmux
Support eMMC, ethernet, gpio key for power button, I2C, PWM, SD card
and UART.
* Others
Enable ethernet, UART1 debug, USB host, USDHC3 for microSD card and
USDHC4 for built-in eMMC storage.
