Subject: [PATCH 1/4] arm64: dts: allwinner: add 'chassis-type' property
Date: Sat, 16 Oct 2021 12:20:22 +0200	[thread overview]
Message-ID: <20211016102025.23346-2-arnaud.ferraris@collabora.com> (raw)
In-Reply-To: <20211016102025.23346-1-arnaud.ferraris@collabora.com>

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.
