= 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.
adsp {
compatible = "qcom,msm8974-adsp-pil";
interrupts-extended = <&intc 0 162 IRQ_TYPE_EDGE_RISING>,
<&adsp_smp2p_in 0 IRQ_TYPE_EDGE_RISING>,
<&adsp_smp2p_in 1 IRQ_TYPE_EDGE_RISING>,
<&adsp_smp2p_in 2 IRQ_TYPE_EDGE_RISING>,
<&adsp_smp2p_in 3 IRQ_TYPE_EDGE_RISING>;
interrupt-names = "wdog",
"fatal",
"ready",
"handover",
"stop-ack";

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