I'd guess it's just because that's the standard set of headphone buttons that Intel uses for their platforms.

[PATCH] ASoC: atmel: ATMEL drivers depend on HAS_DMA
by Randy Dunlap 28 Jun '21

28 Jun '21

On a config (such as arch/sh/) which does not set HAS_DMA when MMU is not set, several ATMEL ASoC drivers select symbols that cause kconfig warnings. There is one "depends on HAS_DMA" here but several more are needed to prevent kconfig warnings since 'select' does not recognize any dependencies. Fix the following kconfig warnings: WARNING: unmet direct dependencies detected for SND_ATMEL_SOC_PDC Depends on [n]: SOUND [=m] && !UML && SND [=m] && SND_SOC [=m] && SND_ATMEL_SOC [=m] && HAS_DMA [=n] Selected by [m]: - SND_ATMEL_SOC_SSC [=m] && SOUND [=m] && !UML && SND [=m] && SND_SOC [=m] && SND_ATMEL_SOC [=m] - SND_ATMEL_SOC_SSC_PDC [=m] && SOUND [=m] && !UML && SND [=m] && SND_SOC [=m] && SND_ATMEL_SOC [=m] && ATMEL_SSC [=m] WARNING: unmet direct dependencies detected for SND_ATMEL_SOC_SSC_PDC Depends on [n]: SOUND [=m] && !UML && SND [=m] && SND_SOC [=m] && SND_ATMEL_SOC [=m] && ATMEL_SSC [=m] && HAS_DMA [=n] Selected by [m]: - SND_AT91_SOC_SAM9G20_WM8731 [=m] && SOUND [=m] && !UML && SND [=m] && SND_SOC [=m] && SND_ATMEL_SOC [=m] && (ARCH_AT91 || COMPILE_TEST [=y]) && ATMEL_SSC [=m] && SND_SOC_I2C_AND_SPI [=m] WARNING: unmet direct dependencies detected for SND_ATMEL_SOC_SSC Depends on [n]: SOUND [=m] && !UML && SND [=m] && SND_SOC [=m] && SND_ATMEL_SOC [=m] && HAS_DMA [=n] Selected by [m]: - SND_ATMEL_SOC_SSC_DMA [=m] && SOUND [=m] && !UML && SND [=m] && SND_SOC [=m] && SND_ATMEL_SOC [=m] && ATMEL_SSC [=m] WARNING: unmet direct dependencies detected for SND_ATMEL_SOC_SSC_DMA Depends on [n]: SOUND [=m] && !UML && SND [=m] && SND_SOC [=m] && SND_ATMEL_SOC [=m] && ATMEL_SSC [=m] && HAS_DMA [=n] Selected by [m]: - SND_ATMEL_SOC_WM8904 [=m] && SOUND [=m] && !UML && SND [=m] && SND_SOC [=m] && SND_ATMEL_SOC [=m] && (ARCH_AT91 || COMPILE_TEST [=y]) && ATMEL_SSC [=m] && I2C [=m] - SND_AT91_SOC_SAM9X5_WM8731 [=m] && SOUND [=m] && !UML && SND [=m] && SND_SOC [=m] && SND_ATMEL_SOC [=m] && (ARCH_AT91 || COMPILE_TEST [=y]) && ATMEL_SSC [=m] && SND_SOC_I2C_AND_SPI [=m] Fixes: 3951e4aae2ce ("ASoC: atmel-pcm: dma support based on pcm dmaengine") Fixes: 18291410557f ("ASoC: atmel: enable SOC_SSC_PDC and SOC_SSC_DMA in Kconfig") Fixes: 061981ff8cc8 ("ASoC: atmel: properly select dma driver state") Signed-off-by: Randy Dunlap <rdunlap(a)infradead.org> Cc: Codrin Ciubotariu <codrin.ciubotariu(a)microchip.com> Cc: alsa-devel(a)alsa-project.org Cc: Liam Girdwood <lgirdwood(a)gmail.com> Cc: Mark Brown <broonie(a)kernel.org> Cc: Bo Shen <voice.shen(a)atmel.com> Cc: Michał Mirosław <mirq-linux(a)rere.qmqm.pl> Cc: Alexandre Belloni <alexandre.belloni(a)free-electrons.com> --- sound/soc/atmel/Kconfig | 6 ++++++ 1 file changed, 6 insertions(+) --- linux-next-20210528.orig/sound/soc/atmel/Kconfig +++ linux-next-20210528/sound/soc/atmel/Kconfig @@ -19,12 +19,14 @@ config SND_ATMEL_SOC_DMA config SND_ATMEL_SOC_SSC tristate + depends on HAS_DMA select SND_ATMEL_SOC_DMA select SND_ATMEL_SOC_PDC config SND_ATMEL_SOC_SSC_PDC tristate "SoC PCM DAI support for AT91 SSC controller using PDC" depends on ATMEL_SSC + depends on HAS_DMA select SND_ATMEL_SOC_PDC select SND_ATMEL_SOC_SSC help @@ -34,6 +36,7 @@ config SND_ATMEL_SOC_SSC_PDC config SND_ATMEL_SOC_SSC_DMA tristate "SoC PCM DAI support for AT91 SSC controller using DMA" depends on ATMEL_SSC + depends on HAS_DMA select SND_ATMEL_SOC_DMA select SND_ATMEL_SOC_SSC help @@ -44,6 +47,7 @@ config SND_AT91_SOC_SAM9G20_WM8731 tristate "SoC Audio support for WM8731-based At91sam9g20 evaluation board" depends on ARCH_AT91 || COMPILE_TEST depends on ATMEL_SSC && SND_SOC_I2C_AND_SPI + depends on HAS_DMA select SND_ATMEL_SOC_SSC_PDC select SND_SOC_WM8731 help @@ -54,6 +58,7 @@ config SND_ATMEL_SOC_WM8904 tristate "Atmel ASoC driver for boards using WM8904 codec" depends on ARCH_AT91 || COMPILE_TEST depends on ATMEL_SSC && I2C + depends on HAS_DMA select SND_ATMEL_SOC_SSC_DMA select SND_SOC_WM8904 help @@ -64,6 +69,7 @@ config SND_AT91_SOC_SAM9X5_WM8731 tristate "SoC Audio support for WM8731-based at91sam9x5 board" depends on ARCH_AT91 || COMPILE_TEST depends on ATMEL_SSC && SND_SOC_I2C_AND_SPI + depends on HAS_DMA select SND_ATMEL_SOC_SSC_DMA select SND_SOC_WM8731 help

Starting with 1.2.5 alsactl tries to initialize UCM even if it is not supported
by GitHub issues - edited 27 Jun '21

27 Jun '21

alsa-project/alsa-utils issue #101 was edited from nmeum: Starting with alsa-utils 1.2.5 I observed the following warning on my machine when running `alsactl restore 0`, which I didn't receive prevously with alsa-utils 1.2.4: ``` $ alsactl -E 'HOME=/var/run/alsasound' -I -f /var/lib/alsa/asound.state restore 0 alsa-lib parser.c:2372:(load_toplevel_config) Unable to find the top-level configuration file '/usr/share/alsa/ucm2/ucm.conf'. alsa-lib main.c:1405:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -2 ``` The error message tells me that alsa-utils 1.2.5 now tries to initialize UCM by default which doesn't work since I don't have [alsa-ucm-conf](https://github.com/alsa-project/alsa-ucm-conf) installed. After installing alsa-ucm-conf, the error message looks as follows: ``` $ alsactl -E 'HOME=/var/run/alsasound' -I -f /var/lib/alsa/asound.state restore 0 alsa-lib parser.c:242:(error_node) UCM is not supported for this HDA model (HDA Intel PCH at 0xf2530000 irq 35) alsa-lib main.c:1405:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -6 ``` >From reading the alsactl man page, it seems to me that UCM should only be initialized by default if it is available. Since alsactl 1.2.4 did not attempt to initialize UCM on my machine, this seems to be a regression introduced in alsactl 1.2.5. If I disable UCM explicitly using `alsactl -U`, everything works as expected. Similarly, downgrading to alsactl 1.2.4 again also resolves the issue. I am not familiar at all with alsa internals but if desired, I can check with `git-bisect(1)` which commit between `v1.2.4..v1.2.5` introduced this regression.

alsa-project/alsa-utils issue #101 was opened from nmeum: Hello, Starting with alsa-utils 1.2.5 I observed the following warning on my machine when running `alsactl restore 0`, which I didn't receive prevously with alsa-utils 1.2.4: ``` $ alsactl -E 'HOME=/var/run/alsasound' -I -f /var/lib/alsa/asound.state restore 0 alsa-lib parser.c:2372:(load_toplevel_config) Unable to find the top-level configuration file '/usr/share/alsa/ucm2/ucm.conf'. alsa-lib main.c:1405:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -2 ``` The error message tells me that alsa-utils 1.2.5 now tries to initialize UCM by default which doesn't work since I don't have [alsa-ucm-conf](https://github.com/alsa-project/alsa-ucm-conf) installed. After installing alsa-ucm-conf, the error message looks as follows: ``` $ alsactl -E 'HOME=/var/run/alsasound' -I -f /var/lib/alsa/asound.state restore 0 alsa-lib parser.c:242:(error_node) UCM is not supported for this HDA model (HDA Intel PCH at 0xf2530000 irq 35) alsa-lib main.c:1405:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -6 ``` >From reading the alsactl man page, it seems to me that UCM should only be initialized by default if it is available. Since alsactl 1.2.4 did not attempt to initialize UCM on my machine, this seems to be a regression introduced in alsactl 1.2.5. If I disable UCM explicitly using `alsactl -U`, everything works as expected. Similarly, downgrading to alsactl 1.2.4 again also resolves the issue. I am not familiar at all with alsa internals but if desired, I can check with `git-bisect(1)` which commit between `v1.2.4..v1.2.5` introduced this regression.
