[PATCH 1/2] ASoC: wm_adsp: Declare firmware controls from codec driver

[PATCH 1/2] ASoC: wm_adsp: Declare firmware controls from codec driver

[Richard Fitzgerald]

To allow for more flexibility in naming of DSP-type cores
move the creation of the firmware controls to the codec
drivers instead of having a hardcoded list in wm_adsp.

[PATCH 2/2] ASoC: wm_adsp: Make DSP name configurable by codec driver

[Richard Fitzgerald]

Instead of harcoding that a core must always be called "DSPn"
add a name member to struct wm_adsp so that the owning codec
driver can provide a custom name. This allows for re-use of
the wm_adsp driver with parts where the processing cores are
named differently.

If no name is provided the default DSPn name is used.

Applied "ASoC: wm_adsp: Make DSP name configurable by codec driver" to the asoc tree

[Mark Brown]

The patch

   ASoC: wm_adsp: Make DSP name configurable by codec driver

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: wm_adsp: Declare firmware controls from codec driver" to the asoc tree

[Mark Brown]

The patch

   ASoC: wm_adsp: Declare firmware controls from codec driver

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: wm_adsp: Declare firmware controls from codec driver

To allow for more flexibility in naming of DSP-type cores
move the creation of the firmware controls to the codec
drivers instead of having a hardcoded list in wm_adsp.
