[PATCH v2] ARM: dts: at91: add devicetree for the Axentia Nattis with Natte power

From: Peter Rosin
Date: Mon Dec 04 2017 - 08:57:30 EST

The Axentia Nattis is a device designed for presenting departures for
public transport systems. The Natte helper board provides power and
features a battery of battery chargers.

This was part of a two-patch series, but the first patch in that
series was redundant, so I dropped it (there was a dt binding
recently added for the tfa9879 amplifier that I had not noticed).

Changes since v1: https://lkml.org/lkml/2017/12/1/844
- removed chip-ids from before the @-sign instead naming the nodes
for the function, e.g sx1502q@20 -> ioexp@20
- added #sound-dai-cells to the amplifier node
- switch to SPDX license tags

Cheers,
Peter
