[PATCH 0/4] spi: spi-fsl-dspi: Target mode improvements

[James Clark]

Improve usability of target mode by reporting FIFO errors and increasing
the buffer size when DMA is used. While we're touching DMA stuff also
switch to non-coherent memory, although this is unrelated to target
mode.

The first commit is marked as a fix because it can fix intermittent
issues with existing transfers, rather than the later fixes which
improve larger than FIFO target mode transfers which would have never
worked.
