[PATCH V2 0/2] mt7981b: initial DT code

[Rafał Miłecki]

From: Rafał Miłecki <rafal@milecki.pl>

This work is based on linux-next content and was successfully verified
using "dtbs_check".

I'm not sure who should apply this work. Given I received reviews from
AngeloGioacchino should I expect Arnd to pick it to his tree directly?

[PATCH V2 2/2] arm64: dts: mediatek: Add initial MT7981B and Xiaomi AX3000T

[Rafał Miłecki]

From: Rafał Miłecki <rafal@milecki.pl>

MT7981B (AKA MediaTek Filogic 820) is a dual-core ARM Cortex-A53 SoC.
One of market devices using this SoC is Xiaomi AX3000T.

This is initial contribution with basic SoC support. More hardware block
will get added later. Some will need their bindings (like auxadc).

This is MediaTek and gets picked by MediaTek maintainers - either me or Matthias.
