-= SUBNODES
-The adsp node may have an subnode named "glink-edge" that describes the
-communication edge, channels and devices related to the Hexagon.
-See ../soc/qcom/qcom,glink.txt for details on how to describe these.
-
-= EXAMPLE
-The following example describes the resources needed to boot control the
-ADSP, as it is found on SDM845 boards.
