Conor Dooley 8853aab167 mailbox: mpfs: switch to txdone_poll ... [ Upstream commit b5984a9844 ] The system controller on PolarFire SoC has no interrupt to signify that the TX has been completed. The interrupt instead signals that a service requested by the mailbox client has succeeded. If a service fails, there will be no interrupt delivered. Switch to polling the busy register to determine whether transmission has completed.
