c9afc183 - ASoC: dwc: Disallow building designware_pcm as a module

Fri, 28 Apr 2017 09:55:25 +0000

ASoC: dwc: Disallow building designware_pcm as a moduleDesignware PCM is an extension to Designware I2S and they are dependenton each other. For this reason, make Designware PCM a boolean which willcompile with Desigwnare I2S module. The name of the module is not changedbut the name of the files need to be changed.Also, without this commit we get errors when probbing designware_i2s modulebecause of unspecified license:designware_pcm: module license 'unspecified' taints kernel.Disabling lock debugging due to kernel taintdesignware_pcm: Unknown symbol __rcu_read_lock (err 0)designware_pcm: Unknown symbol devm_snd_soc_register_platform (err 0)designware_pcm: Unknown symbol synchronize_rcu (err 0)designware_pcm: Unknown symbol __rcu_read_unlock (err 0)designware_pcm: Unknown symbol snd_soc_set_runtime_hwparams (err 0)So, this is really needed as a fix.Fixes: 79361b2b98b7 ("ASoC: dwc: Add PIO PCM extension")Signed-off-by: Lubomir Rintel Signed-off-by: Jose Abreu Signed-off-by: Mark Brown List of files: /linux-6.15/sound/soc/dwc/Makefile

3276d0aa - ASoC: dwc: make pcm support built-in when necessary

Mon, 20 Jun 2016 16:01:19 +0000

ASoC: dwc: make pcm support built-in when necessaryThe new PIO mode for the dwc audio driver causes a link failurewhen it is built as a loadable module but the audio driver is built-in:sound/built-in.o: In function `i2s_irq_handler'::(.text+0x58c64): undefined reference to `dw_pcm_push_tx'sound/built-in.o: In function `dw_i2s_probe'::(.text+0x593dc): undefined reference to `dw_pcm_register'We could link both into a single module, but apparently theauthor intended them to be separate, so this instead changesthe Makefile to force the pcm module to be built-in if thebase module is. This is a bit hacky but not as bad as tryingto work around it in Kconfig language.Signed-off-by: Arnd Bergmann Fixes: 79361b2b98b7 ("ASoC: dwc: Add PIO PCM extension")Signed-off-by: Mark Brown List of files: /linux-6.15/sound/soc/dwc/Makefile

79361b2b - ASoC: dwc: Add PIO PCM extension

Thu, 09 Jun 2016 11:47:05 +0000

ASoC: dwc: Add PIO PCM extensionA PCM extension was added to I2S driver so that audiosamples are transferred using PIO mode.The PCM supports two channels @ 16 or 32 bits with rates32k, 44.1k and 48k.Although the mainline I2S driver uses ALSA DMA engine theI2S controller can be built without DMA support, thereforethis is the reason why this extension was added.Signed-off-by: Jose Abreu Cc: Carlos Palminha Cc: Mark Brown Cc: Liam Girdwood Cc: Jaroslav Kysela Cc: Takashi Iwai Cc: Rob Herring Cc: Alexey Brodkin Cc: linux-snps-arc@lists.infradead.orgCc: alsa-devel@alsa-project.orgCc: linux-kernel@vger.kernel.orgSigned-off-by: Mark Brown List of files: /linux-6.15/sound/soc/dwc/Makefile
