Subject: Applied "spi: imx: initialize usedma earlier" to the spi tree
Date: Fri, 26 Feb 2016 11:48:01 +0900 [thread overview]
Message-ID: <E1aZ8Rl-0006bJ-Fc@finisterre> (raw)
In-Reply-To: <1455715739-25161-6-git-send-email-s.hauer-bIcnvbaLZ9MEGnE8C9+IrQ@public.gmane.org>
The patch
spi: imx: initialize usedma earlier
has been applied to the spi tree at
git://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

Subject: [PATCH] spi: imx: initialize usedma earlier
The SoC specific config function does not know if DMA will be used or
not. This information will be useful to configure the SPI controller
correctly for DMA in following patches, so initialize the usedma
variable before calling into the SoC specific config function.
