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.

This commit changes the behaviour to select the SPI_IO_TYPE_DMA mode if DMA channels are defined in the DT and will keep SPI_IO_TYPE_INTR if the channels are not defined in it.
