Richard Fitzgerald 18f50b8304 soundwire: cadence: Don't overflow the command FIFOs ... [ Upstream commit 7cbfee2e2e ] The command FIFOs in the Cadence IP can be configured during design up to 32 entries, and the code in cadence_master.c was assuming the full 32-entry FIFO. But all current Intel implementations use an 8-entry FIFO. Up to now the longest message used was 6 entries so this wasn't causing any problem. But future Cirrus Logic codecs have downloadable firmware or tuning blobs. It is more efficient for the codec driver to issue long transfers that can take advantage of any queuing in the Soundwire controller and avoid the overhead of repeatedly writing the page registers.
