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.

It's kind of pointless to have "i2se,duckbill" if you use the same one
for all these boards.

At the moment, this is only used to fix-up the MAC address' OUI part
in mxs_machine_init. So my proposal would be to use
compatible = "i2se,duckbill-2", "fsl,imx28";
for the Duckbill 2 board and something like
compatible = "i2se,duckbill-2-485", "i2se,duckbill-2", "fsl,imx28";
for the rest. This way we need to add only one additional check in mxs_machine_init check.
Would this be a way to go?
Best regards,
Michael

From: Michael Heimpold <mhei@heimpold.de>
This machine is based on I2SE's Duckbill 2 board and is sold as part
of I2SE's PLC Bundle for IoT. This is a development kit for Homeplug
Green PHY based powerline products based on Qualcomms QCA7000 chip.
