For example, > what does this "arm,poll-transport" can possibly mean for SMC/Optee transport ? It actually is a property of the transport, except it applies to all transports (mailbox, smc, virtio). For Optee transport, this is implicitly true, since Optee transport always uses polling in any case, so the property has no effect. > I understand this is a valid request, just not sure if this is the right way > to solve( i.e. Adding this property in the SCMI node in the proposed form). > > Let me think and give others a chance to express their opinion.
