This series fixes some bugs I found while running spi-loopback-test with
spi-s3c64xx.  The first problem (which I actually noticed while trying to fix
the second problem with transfers >64KiB) seems to be a generic issue which
affects several drivers so I fixed it in the core.

The series has been tested on ARTPEC-8, which has a version of the IP similar
to Exynos 7 and with 64 byte FIFOs (compatible with "tesla,fsd-spi").

Thanks!

[1/4] spi: spi-loopback-test: Add test to trigger DMA/PIO mixing
      commit: b85ad8a54e0a446b3daa7f526e4996ddb6d4373f

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
