Conor Dooley 4cf71779ea 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.
