-Qualcomm GLINK edge binding
-
-This binding describes a Qualcomm GLINK edge, a fifo based mechanism for
-communication between subsystem-pairs on various Qualcomm platforms. Two types
-of edges can be described by the binding; the GLINK RPM edge and a SMEM based
-edge.
-
-- compatible:
- Usage: required for glink-rpm
- Value type: <stringlist>
- Definition: must be "qcom,glink-rpm"
-
-- label:
- Usage: optional
- Value type: <string>
- Definition: should specify the subsystem name this edge corresponds to.
-
-- interrupts:
- Usage: required
- Value type: <prop-encoded-array>
- Definition: should specify the IRQ used by the remote processor to
- signal this processor about communication related events
-
-- qcom,remote-pid:
- Usage: required for glink-smem
- Value type: <u32>
- Definition: specifies the identifier of the remote endpoint of this edge
-
-- qcom,rpm-msg-ram:
- Usage: required for glink-rpm
- Value type: <prop-encoded-array>
- Definition: handle to RPM message memory resource
-
-- mboxes:
- Usage: required
- Value type: <prop-encoded-array>
- Definition: reference to the "rpm_hlos" mailbox in APCS, as described
- in mailbox/mailbox.txt
-
-= GLINK DEVICES
-Each subnode of the GLINK node represent function tied to a virtual
-communication channel. The name of the nodes are not important. The properties
-of these nodes are defined by the individual bindings for the specific function
-- but must contain the following property:
-
-- qcom,glink-channels:
- Usage: required
- Value type: <stringlist>
- Definition: a list of channels tied to this function, used for matching
- the function to a set of virtual channels
-
-- qcom,intents:
- Usage: optional
- Value type: <prop-encoded-array>
- Definition: a list of size,amount pairs describing what intents should
- be preallocated for this virtual channel. This can be used
- to tweak the default intents available for the channel to
- meet expectations of the remote.
-
-= EXAMPLE
-The following example represents the GLINK RPM node on a MSM8996 device, with
-the function for the "rpm_request" channel defined, which is used for
-regulators and root clocks.
