= SUBNODES
|
|
The adsp node may have an subnode named either "smd-edge" or "glink-edge" that
|
|
describes the communication edge, channels and devices related to the ADSP.
|
|
See ../soc/qcom/qcom,smd.txt and ../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 MSM8974 boards.

|
|
|
|
The following example describes the resources needed to boot control the
|
|
SLPI, as it is found on MSM8996 boards.
|
|
|
