The MT8186 Steelix, also known as the Lenovo 300e Yoga Chromebook Gen 4, is a convertible device based on a common design of the same name. The device comes in different variants. Of them, whether a world facing camera is integrated is the only differentiating factor between the two device trees added. The different SKU IDs describe this alone. The other device difference is the touchpad component used. This is simply handled by having both possible components described in the device tree, and letting the implementation figure out which one is actually available. The system bootloader / firmware does not differentiate this in that they share the same SKU IDs.
