Subject: [PATCH 1/4] arm64: dts: allwinner: add 'chassis-type' property
Date:   Sat, 16 Oct 2021 12:20:22 +0200

A new 'chassis-type' root node property has recently been approved for
the device-tree specification, in order to provide a simple way for
userspace to detect the device form factor and adjust their behavior
accordingly.

This patch fills in this property for end-user devices (such as laptops,
smartphones and tablets) based on Allwinner ARM64 processors.
