-For various board the "board" node may contain specific properties
-that pertain to this particular board, such as board-specific GPIOs.
-
-Required root node property: src
-- Nomadik System and reset controller used for basic chip control, clock
-  and reset line control.
-- compatible: must be "stericsson,nomadik,src"

-Boards with the Nomadik SoC include:
