[PATCH 0/7] ASoC: pxa: code refactoring

[PATCH 0/7] ASoC: pxa: code refactoring

[Daniel Mack]

This is a series to clean up the code base in the ASoC/PXA area a bit.
It folds some implementations, removes some files and brings pcm ops to
the CPU DAIS, so they can be used on DT platforms without platform
drivers.

They are a preparation for some more patches that will follow on top.

Daniel Mack (7):
  ASoC: fold pxa2xx-pcm into its only user, pxa2xx-ac97
  ASoC: pxa: clean up function names in pxa2xx-lib
  ASoC: pxa: move some functions to pxa2xx-lib
  ASoC: pxa2xx-pcm-lib: fix indenting
  ASoC: pxa: provide PCM ops for ssp, i2s and ac97 components
  ASoC: pxa: remove bindings from pxa2xx-pcm
  ASoC: pxa: make SND_PXA2XX_SOC_I2S selectable

[PATCH 1/7] ASoC: fold pxa2xx-pcm into its only user, pxa2xx-ac97

[Daniel Mack]

Now that the PXA SSP bits are ported over to generic DMA, the pxa2xx-pcm
code only has a single user left. This patch folds the remaining bits into
its only user and removes the unnecessary glue layer along with its header
file.

The include dependency to linux/dma/pxa-dma.h is also gone now.

[PATCH 2/7] ASoC: pxa: clean up function names in pxa2xx-lib

[Daniel Mack]

Clean up the namespace a bit and drop the __ prefix of all functions
exported by pxa2xx-lib. This improves the readability of the code.

[PATCH 3/7] ASoC: pxa: move some functions to pxa2xx-lib

[Daniel Mack]

To get rid of some intermediate platform layers, move pxa2xx_soc_pcm_new()
and pxa2xx_pcm_ops in pxa2xx-lib.

[PATCH 5/7] ASoC: pxa: provide PCM ops for ssp, i2s and ac97 components

[Daniel Mack]

Now that the functions are now available through pxa2xx-lib, hook them up
to pxa-sspi, pxa-ac97 and pxa-i2s. This allows DT platforms to use the DAIs
without a platform driver.

[PATCH 6/7] ASoC: pxa: remove bindings from pxa2xx-pcm

[Daniel Mack]

This platform is no longer needed on DT boards, so let's remove them to
avoid confusion. DT bindings should use the CPU DAIs (I2S/SSP/AC97)
directly.

Applied "ASoC: pxa: make SND_PXA2XX_SOC_I2S selectable" to the asoc tree

[Mark Brown]

The patch

   ASoC: pxa: make SND_PXA2XX_SOC_I2S selectable

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

Applied "ASoC: pxa: remove bindings from pxa2xx-pcm" to the asoc tree

[Mark Brown]

The patch

   ASoC: pxa: remove bindings from pxa2xx-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

Subject: [PATCH] ASoC: pxa: remove bindings from pxa2xx-pcm

This platform is no longer needed on DT boards, so let's remove them to
avoid confusion. DT bindings should use the CPU DAIs (I2S/SSP/AC97)
directly.

Applied "ASoC: fold pxa2xx-pcm into its only user, pxa2xx-ac97" to the asoc tree

[Mark Brown]

The patch

   ASoC: fold pxa2xx-pcm into its only user, pxa2xx-ac97

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: fold pxa2xx-pcm into its only user, pxa2xx-ac97

Now that the PXA SSP bits are ported over to generic DMA, the pxa2xx-pcm
code only has a single user left. This patch folds the remaining bits into
its only user and removes the unnecessary glue layer along with its header
file.

The include dependency to linux/dma/pxa-dma.h is also gone now.
