The LG Optimus Black codename sniper is a smartphone that was designed and
manufactured by LG Electronics (LGE) and released back in 2011.
It is using an OMAP3630 SoC, GP version.

This adds devicetree support for the device, with only a few basic features
supported, such as debug uart, i2c, internal emmc and external mmc.
