Leonard Crestez 26d0fba29c firmware: imx: scu: Ensure sequential TX ... SCU requires that all messages words are written sequentially but linux MU driver implements multiple independent channels for each register so ordering between different channels must be ensured by SCU API interface. Wait for tx_done before every send to ensure that no queueing happens at the mailbox channel level.
