Johan Hovold 3094f94773 greybus: connection: add support for high-priority connections ... Add connection flag to indicate that a connection has high priority. For the SVC and control connections this may be used by the host-device driver as a hint to allocate dedicated DMA channels or to use polling to avoid message congestion. We also allow drivers to set this flag on their connections, even though we currently have no use case for this (and the host-device driver is again free to ignore it). Note that this mechanism can be used to indicate also high-bandwidth connections (e.g. wanting larger buffers or dedicated endpoints), but that that should be done using a separate high-bandwidth flag rather than overloading the high-priority flag.
