Improve usability of target mode by reporting FIFO errors and increasing

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.

Thanks!

[1/4] spi: spi-fsl-dspi: Clear completion counter before initiating transfer

[2/4] spi: spi-fsl-dspi: Use non-coherent memory for DMA

[3/4] spi: spi-fsl-dspi: Increase DMA buffer size
(no commit info)
[4/4] spi: spi-fsl-dspi: Report FIFO overflows as errors
(no commit info)

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark


Hi Mark,

Not sure if this is a mistake in the notification or not, but this one shouldn't be applied. There is a v4 with some issues. Although the notification on V4 that patch 1 was applied is OK.

Thanks
James
