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@xxxxxxxxxxxxx> Cc: Codrin Ciubotariu <codrin.ciubotariu@xxxxxxxxxxxxx> Cc: alsa-devel@xxxxxxxxxxxxxxxx Cc: Liam Girdwood <lgirdwood@xxxxxxxxx> Cc: Mark Brown <broonie@xxxxxxxxxx> Cc: Michał Mirosław <mirq-linux@xxxxxxxxxxxx> Cc: Alexandre Belloni <alexandre.belloni@xxxxxxxxxxxxxxxxxx> --- v2: rebase & resend; drop Cc: to Bo Shen <voice.shen@xxxxxxxxx> # bounced sound/soc/atmel/Kconfig | 6 ++++++ 1 file changed, 6 insertions(+) --- linux-next-20210628.orig/sound/soc/atmel/Kconfig +++ linux-next-20210628/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
