I'm mostly using overlays to describe custom test hardware that
is connection to expansion connectors on standard development boards.
These fall into one of two classes:
  1. Overlays enabling an on-SoC device and configuring access to it from
     an expansion connector,
  2. Overlays describing hardware connected to a device from class1.

Class 1 overlays are SoC and board-specific, so they belong in e.g.
arch/arm/boot/dts/.
Class 2 overlays are more universal (depending on what they extend; Pantelis'
connectors work may help here), so they can be shared between architectures.

Other people may have other use cases.

when I'm talking to journalists I just say "programmer" or something like that.
