[PATCH 0/7] ASoC: omap: Deprecate omap-pcm for sdma-pcm

[Peter Ujfalusi]

Hi,

omap-pcm served us well over the years, but there is no reason to keep it around
as we can rely on generic dmaengine_pcm code without the need to maintain custom
code.

The series has been tested on:
omap3 beagle-xm, omap4 PandaES, omap4 Blaze (SDP), am57xx beagle-x15, dra7 evm.

McBSP, McASP, McPDM, DMIC and HDMI audio was tested and I have found no issue
with them.

I was not able to test on OMAP1 or OMAP2 for various reasons, but mainly because
neither Nokia 770 or Nokia n810 audio probes with linux-next. It does not matter
if I have omap-pcm or sdma-pcm...

I would be grateful if someone can give tested-by or pointers on how to get
770/n810 audio working.

Regards,
Peter

[PATCH 1/7] ASoC: omap: Introduce the generic_dmaengine_pcm based sdma-pcm

[Peter Ujfalusi]

With the generic dmaengine_pcm support the omap-cpm can be replaced with a
much smaller wrapper.

CPU DAI drivers can use the:
int sdma_pcm_platform_register(struct device *dev,
			       char *txdmachan, char *rxdmachan);

To register the platform driver, txdmachan/rxdmachan is only needed to be
provided if the DMA channel names are not standard tx/rx, like in case of
McPDM, or the DAI is only capable of one audio direction (DMIC, HDMI).

This patch only introduces the source file and changes to the
Kconfig/Makefile, but does not change any of the DAI drivers to use it.

[PATCH 7/7] ASoC: omap: Mark the omap-pcm as deprecated, but keep it in the tree

[Peter Ujfalusi]

All DAI drivers are now using the new sdma-pcm platform driver. Do not
build the omap-pcm, but keep the sources for one kernel cycle for easier
comparison of omap-pcm and sdma-pcm if there is an interest to do that.

What I noticed some time ago on N810 but not time to fix it that OMAP mux
change dropped muxing audio McBSP pins. Those pins are muxed by reset or

Probably a few lines to arch/arm/boot/dts/omap2420-n810.dts etc.

Hmm do you have a link or commit id to a patch that does the muxing
to see which pins need to be muxed?

FWIW I have this at the moment:
https://pastebin.com/WNT9wnD5

I see that the card is there, but I'm fighting buildroot to have nfs
filesystem with aplay :o

There are few things going to be needed to get things in a shape, like
converting the sound/soc/omap/n810.c to platform driver to be probed via DT.
Proper bindings for the card,
support for mclk handling in aic3x codec driver (n810 is hackinig that in the
machine driver)

In theory audio _should_ work with the DT changes and the fixup in the n810.c...

Should...

Could it have been as old as 5a87cde490e1 ("ARM: OMAP2+: Remove legacy
booting support for n8x0")? At least it is dropping the McBSP muxing
from board-n8x0.c.

Yup OK makes sense. I probably thought it's safe to do as I recall
the Nokia kernels doing all the muxing in the bootloader. But seems
I was wrong, sorry about that.

Cool. The pinctrl fixes at least make sense to me, that could be
a separate patch maybe with Fixes: 5a87cde490e1 ("ARM: OMAP2+: Remove
legacy booting support for n8x0") as pointed out by Jarkko.

The two GPIO for the headphone and speaker amp might also need pinctrl entry.

The clock sys_clkout2 reparenting and rate setting is done with the
assigned-clock stuff.

As I mentioned the only thing that we will need is the mclk handling in the
codec driver.

Most likely we could have a series dealing with DT only, then rewrite the n810.c.

The only thing might cause issue is that if the aic3x driver starts to handle
the sys_clkout2 (mclk) and the n810.c also wants to grab it and control it...
That might break along the way.

The sdma-pcm is working fine on omap2 as well, audio playback and
recording is working on n810 here.

Applied "ASoC: omap-hdmi-audio: Convert to use the sdma-pcm instead of omap-pcm" to the asoc tree

[Mark Brown]

The patch

   ASoC: omap-hdmi-audio: Convert to use the sdma-pcm instead of omap-pcm

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
