Subject: [PATCH v3 1/3] dt-bindings: serial: Allow embedded-controller as
 child node

From: Konrad Dybcio <quic_kdybcio@...cinc.com>

There exist some embedded controllers (like Microsoft SAM found on
Surface devices or Apple Oscar found on old iPhones) that connect to
the host device via serial.

Allow that class of devices to exist under serial interface controller
nodes.
