The serie provides a fix for the spi-stm32 driver, allowing to properly
handle 0 byte transfer (and thus being able to run spi-loopback-test).

In addition to that, important enhancements are implemented, among them,
supporting transfer larger that what the IP can setup in one go or
allowing to use the SPI bus without cs_gpio.

Alain Volmat (5):
  spi: stm32: properly handle 0 byte transfer
  spi: stm32: do not mandate cs_gpio
  spi: stm32h7: ensure message are smaller than max size
  spi: stm32: defer probe for reset
  spi: stm32: make spurious and overrun interrupts visible

Amelie Delaunay (2):
  spi: stm32: use bitfield macros
  spi: stm32h7: replace private SPI_1HZ_NS with NSEC_PER_SEC

Etienne Carriere (1):
  spi: stm32: driver uses reset controller only at init

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
