The patch spi: orion: use new `word_delay` field for SPI transfers has been applied to the spi tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git for-5.5 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 >From 21e26062052c60d31640e614b792473fca787f9f Mon Sep 17 00:00:00 2001 From: Alexandru Ardelean <alexandru.ardelean@xxxxxxxxxx> Date: Thu, 26 Sep 2019 13:51:33 +0300 Subject: [PATCH] spi: orion: use new `word_delay` field for SPI transfers The `word_delay` field had it's type changed to `struct spi_delay`. This allows users to specify nano-second or clock-cycle delays (if needed). Converting to use `word_delay` is straightforward: it just uses the new `spi_delay_exec()` routine, that handles the `unit` part.
