2017-04-05ASoC: soc-core: verify Sound Card normalityKuninori Morimoto
Current ALSA SoC Sound Card basically consists of CPU/Codec/Platform components. If system uses Kernel modules, we can disable these drivers by using rmmod command. In such case, we can't disable CPU/Codec/Platform driver without disabling Sound Card driver. But on the other hand, we can disable these drivers by using unbind command. In such case, we can disable these drivers randomly. In this case, we can create dirty Sound Card which is missing necessary components. (1) If user disabled Sound Card first, but did nothing to other drivers, user can't use Sound because Sound Card is no longer exists. (2) If user disabled CPU/Codec/Platform driver randomly, but did nothing to Sound Card, user still be able to use Sound Card, because dirty Sound Card still exists. In this case, Sound system will be crashed if user started sound playback/capture. But we can't block such random unbind now. To avoid Sound Card crash in (2) case, we need to unregister Sound Card whenever CPU/Codec/Platform component were unregistered. This patch solves this issue.

2017-03-24ASoC: core: remove pointless auxiliary from snd_soc_componentKuninori Morimoto
commit 1a653aa44725 ("ASoC: core: replace aux_comp_list to ...") tried to replace aux_comp_list to component_dev_list, but it failed because of binding timing. Thus, Sylwester fixuped it by commit d2e3a1358c37 ("ASoC: Fix binding and probing of auxiliary..."). One of main purpose of commit 1a653aa44725 ("ASoC: core: replace...") was remove replaceable list (= list_aux) from snd_soc_component by using new "auxiliary" flags (but it failed). Because of this background, current code has reborned card_aux_list (= same as original list_aux), and almost pointless "auxiliary" flags. Let's remove pointless "auxiliary" flags by this patch This means, it is same as revert both commit 1a653aa44725 ("ASoC: core: replace aux_comp_list to ...") and commit d2e3a1358c37 ("ASoC: Fix binding and probing of auxiliary...").

Now that %z is standartised in C99 there is no reason to support %Z. Unlike %L it doesn't even make format strings smaller. Use BUILD_BUG_ON in a couple ATM drivers. In case anyone didn't notice lib/vsprintf.o is about half of SLUB which is in my opinion is quite an achievement. Hopefully this patch inspires someone else to trim vsprintf.c more.

2017-01-17ASoC: core: Add API to use DMI name in sound card long nameLiam Girdwood
Intel DSP platform drivers are used by many different devices but are difficult for userspace to differentiate. This patch adds an API to allow the DMI name to be used in the sound card long name, thereby helping userspace load the correct UCM configuration. Usually machine drivers uses their own name as the sound card name (short name), and leave the long name and driver name blank. This API will use the DMI info like vendor, product and board to make up the card long name. If the machine driver has already explicitly set the long name, this API will do nothing. This patch also allows for further differentiation as many devices that share the same DMI name i.e. Minnowboards, UP boards may be configured with different codecs or firmwares. The API supports flavoring the DMI name into the card longname to provide the extra differentiation required for these devices. For Use Case Manager (UCM) in the user space, changing card long name by this API is backward compatible, since the card name does not change. For a given sound card, even if there is no device-specific UCM configuration file that uses the card long name, UCM will fall back to load the default configuration file that uses the card name.

Currently binding of auxiliary devices doesn't work as in soc_bind_aux_dev() function a bound component is not being added to any list and in soc_probe_aux_devices() we are trying to walk the component_dev_list list to probe auxiliary components but at that time this list doesn't contain any auxiliary components since they are being added to the card only in soc_probe_component(). This patch adds a list to the card where are stored bound but not probed auxiliary devices, so that all aux devices can be probed.

2016-01-10ASoC: Make aux_dev more like a generic componentMengdong Lin
aux_dev is mainly used by the machine driver to specify analog devices, which are registered as codecs. Making it more like a generic component can help the machine driver to use it to specify any component with topology info by name. Details: - Remove the stub 'rtd_aux' array from the soc card. - Add a list 'aux_comp_list' to store the components of aux_devs. And add a list head 'list_aux' to struct snd_soc_component, for adding such components to the above list. - Add a 'init' ops to a component for machine specific init. soc_bind_aux_dev() will set it to be aux_dev's init. And it will be called when probing the component. - soc_bind_aux_dev() will also search components by name of an aux_dev, since it may not be a codec. - Move probing of aux_devs before checking new DAI links brought by topology. - Move removal of aux_devs later than removal of links. Because topology of aux components may register DAIs and the DAI drivers will go with removal of the aux components, we want soc_remove_link_dais() to remove the DAIs at first.
