The Olimex A20-SOM-EVB is an evaluation board for the Olimex
A20-SOM system-on-module. The baseboard provides a full-size SD
socket (connected to mmc3) in addition to the micro-SD socket on
the SOM itself (which is connected to mmc0).
Enable the mmc3 controller in the dts.

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.
