The Olimex A20-SOM-EVB is an evaluation board for the Olimex A20-SOM system-on-module. It provides a set of android-style buttons (labeled "VOL+", "VOL-", "MENU", "SEARCH", "HOME", "ESC" and "ENTER") which are connected to a low-resolution ADC via a resistor network. This patch adds appropriate button definitions to the board dts. The voltages assigned to the keys are specified in the board schematics published by the manufacturer.
