Subject[PATCH] ARM: dts: Add omap3-echo
Date
This is the first generation Amazon Echo from 2016.
Audio support is not yet implemented.

Signed-off-by: André Hentschel <nerv@dawncrow.de>
---

I have local patches for the microphone array, but cleaning that up will take some time.
Audio output seems to be even harder work...
You can find a tutorial on how to boot the Echo here:
