Some of these logical channels are exposed to user space and we need a way to distinguish them there. In the current implementation of SMD this value goes straight into an sysfs attribute that we can use when writing udev rules and for the DIAG implementation to pair up channels related to the same remoteproc. This adds the equivalent information for glink-backed channels. I'm therefor in favor of picking this patch.
