[PATCH 0/7] ARM: dts: support I2SE Duckbill device

[Michael Heimpold]

This series updates/adds Device Tree support for I2SE's Duckbill
device family.

The Duckbill devices are small, pen-drive sized boards based on
NXP's i.MX28 SoC. While the initial variants (Duckbill series) were
equipped with a micro SD card slot only, the latest generation
(Duckbill 2 series) have an additional internal eMMC onboard.

Both device generations consists of four "family members":

- Duckbill/Duckbill 2: generic board, intented to be used as
  baseboard for custom designs and/or as development board

- Duckbill EnOcean/Duckbill 2 EnOcean: come with an EnOcean
  daugther board equipped with the popular TCM310 module

- Duckbill 485/Duckbill 2 485: as the name implies, these
  devices are intended to be used as Ethernet - RS485 converters

- Duckbill SPI/Duckbill 2 SPI: not sold separately, but used
  in I2SE's development kits for Green PHY HomePlug Powerline
  communication

Since all devices are very similar and only differ in few
aspects, the following patch series introduces first common
device tree snippets which are then included by the real
devices. For better understanding, I tried to illustrate the
hierarchy:
