The patch
spi: spi-fsl-dspi: add SPI_LSB_FIRST to driver capabilities
has been applied to the spi tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git
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 00ac9562158e8541d60e91eb72aa9ed0674d4a6a Mon Sep 17 00:00:00 2001 From: Kurt Kanzenbach <kurt@linutronix.de> Date: Mon, 13 Nov 2017 08:47:21 +0100 Subject: [PATCH] spi: spi-fsl-dspi: add SPI_LSB_FIRST to driver capabilities
The driver as well as the controller support the SPI lsb first mode. However, it's not possible to configure it e.g. when using spidev. Adding this flag to mode_bits resolves the issue and lsb first mode can be used.
