2018-11-26ASoC: soc.h: makes snd_soc_of_parse_audio_prefix() inlineKuninori Morimoto1-3/+9
commit 3b7103562c03c ("ASoC: soc-core: add snd_soc_of_parse_node_prefix()") maked snd_soc_of_parse_audio_prefix() as #define. But it'd be better to make this a static inline rather than a #define. It helps with error messages and type safety. This patch makes it inline. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2018-11-23ASoC: soc-core: add snd_soc_of_parse_node_prefix()Kuninori Morimoto1-1/+5
Current ASoC has snd_soc_of_parse_audio_prefix() to get codec_conf settings from DT which is used to avoid DAI naming conflict when CPU/Codec matching. Currently, it is parsing from "top node", but, we want to parse from "each sub node" if sound card had multi cpus/codecs. This patch adds new snd_soc_of_parse_node_prefix() to allow parsing settings from selected node. It is keeping existing snd_soc_of_parse_audio_prefix() by using macro.

2018-11-05ASoC: wm97xx: fix uninitialized regmap pointer problemArnd Bergmann1-1/+1
gcc notices that without either the ac97 bus or the pdata, we never initialize the regmap pointer, which leads to an uninitialized variable access: sound/soc/codecs/wm9712.c: In function 'wm9712_soc_probe': sound/soc/codecs/wm9712.c:666:2: error: 'regmap' may be used uninitialized in this function [-Werror=maybe-uninitialized] Since that configuration is invalid, it's better to return an error here. I tried to avoid adding complexity to the conditions, and turned the #ifdef into a regular if(IS_ENABLED()) check for readability. This in turn requires moving some header file declarations out of an #ifdef. The same code is used in three drivers, all of which I'm changing the same way.

2018-09-12ASoC: core: add support to card rebindSrinivas Kandagatla1-0/+2
Current behaviour of ASoC core w.r.t to component removal is that it unregisters dependent sound card totally. There is no support to rebind the card if the component comes back. Typical use case is DSP restart or kernel modules itself. With this patch, core now maintains list of cards that are unbind due to any of its depended components are removed and card not unregistered yet. This list is cleared when the card is rebind successfully or when the card is unregistered from machine driver. This list of unbind cards are tried to bind once again after every new component is successfully added, giving a fair chance for card bind to be successful.

2018-08-31ASoC: soc-core: use snd_soc_dai_link_component for platformKuninori Morimoto1-0/+2
Current struct snd_soc_dai_link is supporting multicodec, and it is supporting legacy style of codec_name codec_of_node code_dai_name This is handled as single entry of multicodec. We don't have multicpu support yet, but in the future we will. In such case, we can use snd_soc_dai_link_component for both cpu/codec. Then the code will be more simple and readble. As next step, we want to use it for platform, too. This patch adds snd_soc_dai_link_component style for platform. We might have multiplatform support in the future, but we don't know yet. To avoid un-known issue / complex code, this patch supports just single-platform as 1st step. If we could use snd_soc_dai_link_component for all CPU/Codec/Platform, we will switch to new style, and remove legacy code. This is prepare for it.

2018-08-02ASoC: core: remove support for card rebind using component frameworkSrinivas Kandagatla1-7/+0
DRM based audio components get registered inside the component framework bind callback. However component framework has a big mutex lock taken for every call to component_add, component_del and bind, unbind callbacks. This can lead to deadlock situation if we are trying to add new/remove component within a bind/unbind callbacks. Which is what was happening with bcm2837 rpi 3. Revert this change till we sort out the mutex issue.

2018-07-03ASoC: core: Allow topology to override machine driver FE DAI link config.Liam Girdwood1-0/+13
Machine drivers statically define a number of DAI links that currently cannot be changed or removed by topology. This means PCMs and platform components cannot be changed by topology at runtime AND machine drivers are tightly coupled to topology. This patch allows topology to override the machine driver DAI link config in order to reuse machine drivers with different topologies and platform components. The patch supports :- 1) create new FE PCMs with a topology defined PCM ID. 2) destroy existing static FE PCMs 3) change the platform component driver. 4) assign any new HW params fixups. 5) assign a new card name prefix to differentiate this topology to userspace. The patch requires no changes to the machine drivers, but does add some platform component flags that the platform component driver can assign before loading topologies.
