[PATCH 0/4] arm64: dts: add 'chassis-type' property

[Arnaud Ferraris]

Hello,

A new root node property named 'chassis-type' has recently been approved
added to the device tree specification[1]. This will allow userspace to
easily detect the device form factor on DT-based devices, and act
accordingly.

This patchset fills in this property for existing ARM64 consumer
devices (laptops, phones, tablets...).

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,

[PATCH 3/4] arm64: dts: qcom: add 'chassis-type' property

[Arnaud Ferraris]

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 Qualcomm ARM64 processors.

[PATCH 4/4] arm64: dts: rockchip: add 'chassis-type' property

[Arnaud Ferraris]

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 Rockchip ARM64 processors.

I'll add the same for Exynos, S3C and S5P. Do you know by any chance
what is the meaning of "embedded"? How a development board should be
classified?
