[PATCH v3 6/9] ARM: dts: add support for I2SE Duckbill 2 boards

[Michael Heimpold <michael.heimpold-eS4NqCHxEME@public.gmane.org>]

From: Michael Heimpold <mhei-Z/Lg1yOAjpkb1SvskN2V4Q@public.gmane.org>

This machine is an USB pen drive sized development board,
based on NXP's i.MX28 CPU. In contrast to the previous
model "Duckbill", the "Duckbill 2" series has internal
eMMC storage.
