Subject: [PATCH] arm64: mediatek: Propagate chassis-type where possible
Date:   Wed, 17 May 2023 12:11:08 +0200
Message-Id: <20230517101108.205654-1-angelogioacchino.delregno@collabora.com>

The chassis-type string identifies the form-factor of the system:
add this property to all device trees of devices for which the form
factor is known.

Signed-off-by: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com>

I had to ignore some devicetrees as I wasn't sure about the correct
chassis-type of some devices; this raises an issue that we shall solve
when reviewing new DTs, as we shall tell developers to add this
property so that we don't lose track of "what was what".

Even though this property is technically "Optional, Recommended", I
think it's useful to have it as this may (or may not) be actively used
in the future (think about "handset" form factor and thermal envelope).

Cheers!
