Subject[PATCH v2 1/2] dt-bindings: arm: Add optional interrupt to smc/hvc SCMI transport
Date
In normal use of smc/hvc transport in SCMI the message completion is
indicated by the return of the SMC call. This commit provides for an
optional interrupt named "message-serviced" which is used instead to
indicate the completion of a message.

+- interrupts : when using smc or hvc transports, this optional
+ property indicates that msg completion by the platform is indicated
+ by an interrupt rather than by the return of the smc call. This
+ should not be used except when the platform requires such behavior.

+- interrupt-names : if "interrupts" is present, interrupt-names must also
