| D | qcom,glink.txt | 1 Qualcomm GLINK edge binding
3 This binding describes a Qualcomm GLINK edge, a fifo based mechanism for
4 communication between subsystem-pairs on various Qualcomm platforms. Two types
5 of edges can be described by the binding; the GLINK RPM edge and a SMEM based
6 edge.
8 - compatible:
9 Usage: required for glink-rpm
11 Definition: must be "qcom,glink-rpm"
13 - label:
16 Definition: should specify the subsystem name this edge corresponds to.
