[PATCH 00/11] ASoC: qdsp6: Fix dt based module loading

[PATCH 00/11] ASoC: qdsp6: Fix dt based module loading

[Srinivas Kandagatla]

Recent discussion on https://lkml.org/lkml/2018/6/18/1282 suggested
that qdsp6 code is using less common of_platform apis which would
not give dt based module loading support.

Suggestion from Rob was to add compatible strings to the dais nodes
This patchset adds this. Also this patchset has 2 trivial fixes which
is removing redundant owner and fix a error check in q6routing.

Thanks,
srini

[PATCH 06/11] ASoC: qdsp6: q6afe: use of_platform_populate/depopulate()

[Srinivas Kandagatla]

Now that the child nodes have there own compatible strings,
Use of_platform_populate/depopulate() instead of less common
of_platform_device_create()/destroy().

Perhaps have the compatible before #sound-dai-cells
(and #size-cells, #address-cells) like in two previous
patches.

Why is this removed?
If it's a cleanup, perhaps it should be in a separate patch.

I'm not sure if Rob agrees with me or not,
but since this patch is less than 10 lines,
I think that it would be simpler to review
if it was squashed together with the patch
adding the compatible to the DT binding.

You can remove pdev_routing from struct q6adm,
since it is no longer in use.

Since adding the compatible is a prerequisite for using
of_platform_populate()/of_platform_depopulate(),
I think that the patches that make use of
of_platform_populate()/of_platform_depopulate() should
come after the patches that adds the of_table entries.

Since adding the compatible is a prerequisite for using
of_platform_populate()/of_platform_depopulate(),
I think that the patches that make use of
of_platform_populate()/of_platform_depopulate() should
come after the patches that adds the of_table entries.

Applied "ASoC: qdsp6: q6afe: use of_platform_populate/depopulate()" to the asoc tree

[Mark Brown]

The patch

   ASoC: qdsp6: q6afe: use of_platform_populate/depopulate()

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] ASoC: qdsp6: q6afe: use of_platform_populate/depopulate()

Now that the child nodes have there own compatible strings,
Use of_platform_populate/depopulate() instead of less common
of_platform_device_create()/destroy().
