[PATCH V2 0/5] ASoC/arizona: Ensure pin searches use widget name prefix

[PATCH V2 0/5] ASoC/arizona: Ensure pin searches use widget name prefix

[Richard Fitzgerald]

The name of a codec pin can have an optional prefix string, which is
defined by the audio machine driver. The snd_soc_dapm_x_pin functions
take the fully-specified name including the prefix and so the existing
code would fail to find the pin if the audio machine driver had added
a prefix.

This patch chain adds new helper functions that take a non-prefixed name
for a specific ASoC component and internally add that component's prefix.
The other patches update the arizona drivers to use these new functions.

[PATCH V2 1/5] ASoC: core: Add component pin control functions

[Richard Fitzgerald]

It's often the case that a codec driver will need to control its
own pins. However, if a name_prefix has been applied to this codec it
must be included in the name passed to any of the snd_soc_dapm_x_pin()
functions.

The behaviour of the existing pin control functions is reasonable, since
you may want to search for a fully-specified name within the scope of an
entire card. This means that we can't apply the prefix in these functions
because it will break card-scope searches.

Constructing a prefixed string "manually" in codec drivers leads to a lot
of repetition of the same code.

To make this tidier in codec drivers this patch adds a new set of
equivalent functions that take a struct snd_soc_component instead of a
dapm context and automatically add the component's name_prefix to the
given name. This makes it a simple change in codec drivers to be
prefix-safe.

The new functions are not quite trivial enough to be inlines and the
compiler won't be able to compile-away any part of them.

Although it looks somewhat inefficient to have to allocate a temporary
buffer and combine strings, the current design of the widget list
doesn't lend itself to a more optimized implementation - it's a single
list of all widgets on a card and is searched linearly for a matching
string. As pin state changes are generally low-frequency events it's
unlikely to be a significant issue - at least not enough to rewrite the
widget list handling just for this.

Applied "ASoC: core: Add component pin control functions" to the asoc tree

[Mark Brown]

The patch

   ASoC: core: Add component pin control functions

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 V2 2/5] ASoC: arizona: Use component pin control functions

[Richard Fitzgerald]

We need to modify the state of some of our own pins and are currently
not taking account that the pin name may have a name_prefix applied
to it.

Replace the snd_soc_dapm_x_pin functions with the equivalent
snd_soc_component_x_pin functions so that any name_prefix will be
handled automatically.

Applied "ASoC: arizona: Use component pin control functions" to the asoc tree

[Mark Brown]

The patch

   ASoC: arizona: Use component pin control functions

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

Subject: [PATCH] ASoC: arizona: Use component pin control functions

We need to modify the state of some of our own pins and are currently
not taking account that the pin name may have a name_prefix applied
to it.

Replace the snd_soc_dapm_x_pin functions with the equivalent
snd_soc_component_x_pin functions so that any name_prefix will be
handled automatically.

[PATCH V2 3/5] regulator: arizona-micsupp: Use SoC component pin control functions

[Richard Fitzgerald]

The name of a codec pin can have an optional prefix string, which is
defined by the SoC machine driver. The snd_soc_dapm_x_pin functions
take the fully-specified name including the prefix and so the existing
code would fail to find the pin if the audio machine driver had added
a prefix.

Switch to using the snd_soc_component_x_pin equivalent functions that
take a specified SoC component and automatically add the name prefix to
the provided pin name.

Re: [PATCH V2 4/5] extcon: arizona: Use SoC component pin control functions

[Chanwoo Choi]

Hi Richard,

I have no any objection for this patch.

But, the patch4 is dependent on patch1.
After finished the review of patch1,
I'll add acekd-by tag. 

Best Regards,
Chanwoo Choi

[PATCH V2 5/5] Input: arizona-haptics - Use SoC component pin control functions

[Richard Fitzgerald]

The name of a codec pin can have an optional prefix string, which is
defined by the SoC machine driver. The snd_soc_dapm_x_pin functions
take the fully-specified name including the prefix and so the existing
code would fail to find the pin if the audio machine driver had added
a prefix.

Switch to using the snd_soc_component_x_pin equivalent functions that
take a specified SoC component and automatically add the name prefix to
the provided pin name.

Please apply though your tree, I should not have anything conflicting in
mine, and grouped on the same branch the changes make more sense.

Thanks!
