On platforms like LS1021A which use TCFQ mode, an interrupt needs to be processed after each byte is TXed/RXed. I tried to make the DSPI implementation on this SoC operate in other, more efficient modes (EOQ, DMA) but it looks like it simply isn't possible.
This doesn't apply against current code (I guess due to your cleanup series), please check and resend.
