This v1 cover letter is quoted in [1].
For maintainers the table below should help you focus on the patches targetted at you, and ignore the other noise.
The differences since v1 is by maintainers / topic / patch :
- Arnd and Daniel / PXA topic / 0002
devices.c split into pxa25x.c, pxa27x.c and pxa3xx.c
- Boris and Daniel / MTD topic / 0005
Review and ack of this one
- Arnd and netdev / NET topic / 0006 and 0007
Arnd comment taken, review and ack of these one
- Mark and alsa-devel / ASoC topic / 0008
Mark, I couldn't keep your former Ack because :
- I changed one line so that the cpu device provides the DMA
- I added pxa2xx-i2s which was forgotten
Therefore I need a new ack
- Arnd and Daniel / SSP topic / 0013
Review and ack of this one
Happy review.

[1] Former v1 cover letter
This serie is aimed at removing the dmaengine slave compat use, and transfer
knowledge of the DMA requestors into architecture code.
This was discussed/advised by Arnd a couple of years back, it's almost time.
The serie is divided in 3 phasees :
- phase 1 : patch 1/15 and patch 2/15
=> this is the preparation work
- phase 2 : patches 3/15 .. 10/15
=> this is the switch of all the drivers
=> this one will require either an Ack of the maintainers or be taken by them
once phase 1 is merged
- phase 3 : patches 11/15
=> this is the last part, cleanup and removal of export of the DMA filter
function
As this looks like a patch bomb, each maintainer expressing for his tree either
an Ack or "I want to take through my tree" will be spared in the next iterations
of this serie.
Several of these changes have been tested on actual hardware, including :
- pxamci
- pxa_camera
- smc*
- ASoC and SSP

In order to remove the specific knowledge of the dma mapping from PXA
drivers, add a default slave map for pxa architectures.
This won't impact MMP architecture, but is aimed only at all PXA boards.
This is the first step, and once all drivers are converted,
pxad_filter_fn() will be made static, and the DMA resources removed from
device.c.

* [PATCH v2 01/13] dmaengine: pxa: use a dma slave map
@ 2018-05-24 7:06 ` Robert Jarzmik
0 siblings, 0 replies; 118+ messages in thread
From: Robert Jarzmik @ 2018-05-24 7:06 UTC (permalink / raw)
To: linux-arm-kernel
In order to remove the specific knowledge of the dma mapping from PXA
drivers, add a default slave map for pxa architectures.
This won't impact MMP architecture, but is aimed only at all PXA boards.
This is the first step, and once all drivers are converted,
pxad_filter_fn() will be made static, and the DMA resources removed from
device.c.

In order to remove the specific knowledge of the dma mapping from PXA
drivers, add a default slave map for pxa architectures.
This is the first step, and once all drivers are converted,
pxad_filter_fn() will be made static, and the DMA resources removed from
device.c.

linux-media, linux-mmc, linux-mtd, netdev, alsa-devel
In order to remove the specific knowledge of the dma mapping from PXA
drivers, add a default slave map for pxa architectures.
This is the first step, and once all drivers are converted,
pxad_filter_fn() will be made static, and the DMA resources removed from
device.c.
Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr>
Reported-by: Arnd Bergmann <arnd@arndb.de>

Since v1: revamped the SSP part, split into pxa25.c, pxa27x.c and
pxa3xx.c, and add pxa-i2s.

* [PATCH v2 02/13] ARM: pxa: add dma slave map
@ 2018-05-24 7:06 ` Robert Jarzmik
0 siblings, 0 replies; 118+ messages in thread
From: Robert Jarzmik @ 2018-05-24 7:06 UTC (permalink / raw)
To: linux-arm-kernel
In order to remove the specific knowledge of the dma mapping from PXA
drivers, add a default slave map for pxa architectures.
This is the first step, and once all drivers are converted,
pxad_filter_fn() will be made static, and the DMA resources removed from
device.c.
Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr>
Reported-by: Arnd Bergmann <arnd@arndb.de>
---
Since v1: revamped the SSP part, split into pxa25.c, pxa27x.c and
pxa3xx.c, and add pxa-i2s.

As the pxa architecture switched towards the dmaengine slave map, the
old compatibility mechanism to acquire the dma requestor line number and
priority are not needed anymore.
This patch simplifies the dma resource acquisition, using the more
generic function dma_request_slave_channel().

As the pxa architecture switched towards the dmaengine slave map, the
old compatibility mechanism to acquire the dma requestor line number and
priority are not needed anymore.
This patch simplifies the dma resource acquisition, using the more
generic function dma_request_slave_channel().

* [PATCH v2 08/13] ASoC: pxa: remove the dmaengine compat need
@ 2018-05-24 7:06 ` Robert Jarzmik
0 siblings, 0 replies; 118+ messages in thread
From: Robert Jarzmik @ 2018-05-24 7:06 UTC (permalink / raw)
To: linux-arm-kernel
As the pxa architecture switched towards the dmaengine slave map, the
old compatibility mechanism to acquire the dma requestor line number and
priority are not needed anymore.
This patch simplifies the dma resource acquisition, using the more
generic function dma_request_slave_channel().

As the pxa architecture and all its related drivers do not rely anymore
on the filter function, thanks to the slave map conversion, make
pxad_filter_fn() static, and remove it from the global namespace.

Now the dma_slave_map is available for PXA architecture, switch the SSP
device to it.
This specifically means that :
- for platform data based machines, the DMA requestor channels are
extracted from the slave map, where pxa-ssp-dai.<N> is a 1-1 match to
ssp.<N>, and the channels are either "rx" or "tx".
- for device tree platforms, the dma node should be hooked into the
pxa2xx-ac97 or pxa-ssp-dai node.

Now the dma_slave_map is available for PXA architecture, switch the SSP
device to it.
This specifically means that :
- for platform data based machines, the DMA requestor channels are
extracted from the slave map, where pxa-ssp-dai.<N> is a 1-1 match to
ssp.<N>, and the channels are either "rx" or "tx".
- for device tree platforms, the dma node should be hooked into the
pxa2xx-ac97 or pxa-ssp-dai node.

Hi Arnd,
Actually after rereading this, I realised that I completely forgot your former
comment about having a NULL parameter for network devices (as there is no
requestor behind).
I will cook it up for v3 ... that will be a minor change in this patch (hence
I'll keep any Ack), but for patches 0006 and 0007, things will change, and
another patch for Vinod will appear.
Cheers.

Didn't spot it. But, sure, I'm okay with the changes :)

We should, however, merge what's left of this management glue code into
the users of it, so the dma related properties can be put in the right
devicetree node.
I'll prepare a patch for that for 4.18. This is a good preparation for
this round though.
Thanks,
Daniel

The patch
ARM: pxa: change SSP DMA channels allocation
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.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,

Subject: [PATCH] ARM: pxa: change SSP DMA channels allocation
Now the dma_slave_map is available for PXA architecture, switch the SSP
device to it.
This specifically means that :
- for platform data based machines, the DMA requestor channels are
extracted from the slave map, where pxa-ssp-dai.<N> is a 1-1 match to
ssp.<N>, and the channels are either "rx" or "tx".
- for device tree platforms, the dma node should be hooked into the
pxa2xx-ac97 or pxa-ssp-dai node.

The patch
ARM: pxa: change SSP DMA channels allocation
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.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,

Subject: [PATCH] ARM: pxa: change SSP DMA channels allocation
Now the dma_slave_map is available for PXA architecture, switch the SSP
device to it.
This specifically means that :
- for platform data based machines, the DMA requestor channels are
extracted from the slave map, where pxa-ssp-dai.<N> is a 1-1 match to
ssp.<N>, and the channels are either "rx" or "tx".
- for device tree platforms, the dma node should be hooked into the
pxa2xx-ac97 or pxa-ssp-dai node.

The patch
ARM: pxa: remove the DMA IO resources
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.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

Please add any relevant lists and maintainers to the CCs when replying

The patch
ARM: pxa: remove the DMA IO resources
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.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

As the last driver using the former mechanism to acquire the DMA
requestor line has be converted to the dma_slave_map, remove all these
resources from the PXA devices.

The patch
ata: pata_pxa: remove the dmaengine compat need
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.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

Subject: [PATCH] ata: pata_pxa: remove the dmaengine compat need
As the pxa architecture switched towards the dmaengine slave map, the
old compatibility mechanism to acquire the dma requestor line number and
priority are not needed anymore.
This patch simplifies the dma resource acquisition, using the more
generic function dma_request_slave_channel().

The patch
media: pxa_camera: remove the dmaengine compat need
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.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

Please add any relevant lists and maintainers to the CCs when replying

Subject: [PATCH] media: pxa_camera: remove the dmaengine compat need
As the pxa architecture switched towards the dmaengine slave map, the
old compatibility mechanism to acquire the dma requestor line number and
priority are not needed anymore.
This patch simplifies the dma resource acquisition, using the more
generic function dma_request_slave_channel().

As the pxa architecture switched towards the dmaengine slave map, the
old compatibility mechanism to acquire the dma requestor line number and
priority are not needed anymore.
This patch simplifies the dma resource acquisition, using the more
generic function dma_request_slave_channel().

Subject: [PATCH] dmaengine: pxa: use a dma slave map
In order to remove the specific knowledge of the dma mapping from PXA
drivers, add a default slave map for pxa architectures.
This won't impact MMP architecture, but is aimed only at all PXA boards.
This is the first step, and once all drivers are converted,
pxad_filter_fn() will be made static, and the DMA resources removed from
device.c.

The patch
dmaengine: pxa: use a dma slave map
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.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

Subject: [PATCH] dmaengine: pxa: use a dma slave map
In order to remove the specific knowledge of the dma mapping from PXA
drivers, add a default slave map for pxa architectures.
This won't impact MMP architecture, but is aimed only at all PXA boards.
This is the first step, and once all drivers are converted,
pxad_filter_fn() will be made static, and the DMA resources removed from
device.c.

The patch
ASoC: pxa: remove the dmaengine compat need
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.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

The patch
ASoC: pxa: remove the dmaengine compat need
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.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] ASoC: pxa: remove the dmaengine compat need
As the pxa architecture switched towards the dmaengine slave map, the
old compatibility mechanism to acquire the dma requestor line number and
priority are not needed anymore.
This patch simplifies the dma resource acquisition, using the more
generic function dma_request_slave_channel().
