[PATCH 1/6] ASoC: wm5110: Fix up snd_soc_register_platform error path

[PATCH 1/6] ASoC: wm5110: Fix up snd_soc_register_platform error path

[Charles Keepax]

Whilst there is nothing wrong with the error path here it looks a little
bit odd, this patches makes the code a little more idiomatic.

[PATCH 2/6] ASoC: wm_adsp: Use more generic naming for regions and caps definitions

[Charles Keepax]

The region definition will be shared by most firmwares so give this a
more generic name and whilst we are there improve the naming of the
voice control capabilities array as well.

[PATCH 4/6] ASoC: wm5110: Add support for audio trace firmware

[Charles Keepax]

Mainly this adds DAI links for the audio trace, however, it is also
necessary to update the data IRQ handler to check more cores. We have
the handler check every core so it should not be necessary to update
this function if more compressed firmwares are added in the future.

I'm a bit unclear on how exactly we're ensuring that the relevant

So this code is basically just working out which DSP core we
should be opening (at the moment this is fixed a DAI coresponds
to a particular DSP core). At the bottom of the function we call
wm_adsp_compr_open which will check that the firmware supports
compressed operation in the correct direction and will lock out
changes of firmware until compr_free is called.

Thanks,
Charles

Applied "ASoC: wm5102: Add support for the audio trace firmware" to the asoc tree

[Mark Brown]

The patch

   ASoC: wm5102: Add support for the audio trace firmware

has been applied to the asoc tree at

   git://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

[PATCH 6/6] ASoC: wm_adsp: Move setting of DSP speed into CODEC specific code

[Charles Keepax]

The ADSP code should be agnostic of which CODEC it runs upon, currently
there is only one remaining part of the implementation that doesn't
follow this. When the DSP is booted on ADSP2 we read
ARIZONA_SYSTEM_CLOCK_1 and use that to set the initial speed for the DSP
clock. This patch factors that out into CODEC specific code, leaving the
ADSP code entirely CODEC agnostic.

Applied "ASoC: wm_adsp: Move setting of DSP speed into CODEC specific code" to the asoc tree

[Mark Brown]

The patch

   ASoC: wm_adsp: Move setting of DSP speed into CODEC specific code

has been applied to the asoc tree at

   git://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

Thanks,

Subject: [PATCH] ASoC: wm_adsp: Move setting of DSP speed into CODEC specific
 code

The ADSP code should be agnostic of which CODEC it runs upon, currently
there is only one remaining part of the implementation that doesn't
follow this. When the DSP is booted on ADSP2 we read
ARIZONA_SYSTEM_CLOCK_1 and use that to set the initial speed for the DSP
clock. This patch factors that out into CODEC specific code, leaving the
ADSP code entirely CODEC agnostic.
