Hello everyone,

when testing on a SAM9X60 based board with an FPGA implementing a custom
SPI-MEM protocol, we found the need to fully control the delay settings
the atmel/microchip QSPI controller offers.

[1/2] spi: atmel-quadspi: Avoid overwriting delay register settings
      commit: 329ca3eed4a9a161515a8714be6ba182321385c7

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
