[v10,0/5] spi: dw: DW SPI DMA Driver updates

This Patch series adds support for 32 bits per word trasfers using DMA
and some defensive checks around dma controller capabilities.
---
V1 Changes : Add support for AxSize=4 bytes to support 32bits/word.
---
V1->V2 Changes : Add dma capability check to make sure address widths
are supported.
---
V2->V3 Changes : Split changes , add DMA direction check and other
cosmetic chnages.
---
V3->V4 Changes : Fix Sparce Warning

---
V4->V5 Changes : Preserve reverse xmas Tree order, move direction
check before initalisation of further capabilities, remove zero
initialisations, remove error OR'ing.
---
V5->V6 Changes :
	-Remove case of n_bytes=3 using 4_bytes buswidth
	-Avoid forward decaration
	-Break capability check patch into 2
	-round n_bytes to power of 2 ( Bug Fix)
	-Add more explanation in commit text.
---
V6->V7 Changes : Remove extra spaces, refer to functions in commit as
func()
---
V7->V8 Changes : Minor commment updates in patch 4/5
---
V8->V9 Changes : Minor formatting changes in patch 5/5
---
V9->V10 Changes : Moving "return 0" at the end of dw_spi_dma_caps_init() from patch
[4/5] to patch [3/5] to solve :
spi-dw-dma.c: In function ‘dw_spi_dma_caps_init’:
spi-dw-dma.c:100:1: control reaches end of non-void function [-Werror=return-type]

Applied to

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git for-next

Thanks!

[1/5] spi: dw: Add 32 bpw support to SPI DW DMA driver
      commit: 5147d5bfddc807e990a762aed0e56724afeda663
[2/5] spi: dw: Move dw_spi_can_dma()
      commit: d2ae5d42464e990b4d26734c180fbff64233992c
[3/5] spi: dw: Add DMA directional capability check
      (no commit info)
[4/5] spi: dw: Add DMA address widths capability check
      (no commit info)
[5/5] spi: dw: Round of n_bytes to power of 2
      (no commit info)

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

Hello Mark,

This patch seems to be applied already as per the reply to the cover letter:

[1/5] spi: dw: Add 32 bpw support to SPI DW DMA driver
      commit: 5147d5bfddc807e990a762aed0e56724afeda663
[2/5] spi: dw: Move dw_spi_can_dma()
      commit: d2ae5d42464e990b4d26734c180fbff64233992c
[3/5] spi: dw: Add DMA directional capability check
      (no commit info)
[4/5] spi: dw: Add DMA address widths capability check
      (no commit info)
[5/5] spi: dw: Round of n_bytes to power of 2
      (no commit info)

Whereas [3/5] to [5/5] has not been applied.

Do I need to rebase and send the whole series again or resend the last
3 patches based on
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git ?

Thanks
Joy

You need to resend the last three patches, I probably just picked the
wrong one to reply to.
