Originally the driver only utilised the new QDMA engine. The current code still assumes this is the case when locking the IRQ mask register. Since RX now runs on the old style PDMA engine we can add a second lock. This patch reduces the IRQ latency as the TX and RX path no longer need to wait on each other under heavy load.
