Subject[PATCH 2/3] ARM: DTS: AM3517-EVM: Add support for UI board and Audio
Date
The full AM3517-EVM shipped with an add-on board which contained
two Audio codecs, a GPIO expander with a variety of buttons, and
some other features. This patch enables these portions of the UI
board because they don't directly conflict with existing features.
