From: Michael Heimpold <mhei-Z/Lg1yOAjpkb1SvskN2V4Q@public.gmane.org>
This patch updates the Duckbill device tree and synchronize it with
the vendor distributed file. The changes in mostly pin-muxing stuff,
but also some minor fixes. In detail:
- enable SPI pins
- enable I2C pins
- enable UART pins
- enable LRADC pin
- adjust USB DR mode
- add default triggers for LEDs
- get rid of regulators simple-bus container
- adjust phy reset duration
According to phy datasheet, 25ms are sufficient. This also reduces
the time to boot the system.

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.
