     79= SUBNODES
     80A required subnode of the WCNSS PIL is used to describe the attached rf module

    112The wcnss node can also have an subnode named "smd-edge" that describes the SMD
    113edge, channels and devices related to the WCNSS.
    114See ../soc/qcom/qcom,smd.yaml for details on how to describe the SMD edge.

    116= EXAMPLE
    117The following example describes the resources needed to boot control the WCNSS,
    118with attached WCN3680, as it is commonly found on MSM8974 boards.
