Currently we are searching dai name in snd_soc_find_dai, which could either be dai driver name or component device name(for legacy naming). Allow searching dai driver name in snd_soc_find_dai too, so that we can use dai driver name to find legacy naming dais.

Basically, current ALSA SoC framework is based on CPU/Codec/Platform, but its operation doesn't have consistent. Thus, source code was unreadable, and difficult to understand. This patch connects each component (= CPU/Codec/Platform) to rtd by using snd_soc_rtdcom_add(), and convert uneven operations to consistent operation.

Current snd_soc_pcm_runtime has platform / codec pointers, and we could use these specific pointer. But these will be replaced to more generic "component" soon, and will need more generic method to get each connected component pointer from rtd. This patch adds new snd_soc_rtdcom_xxx() to connect/disconnect component to rtd. It means same as previous "platform" / "codec" pointer style, but more generic. We can find necessary component pointer from rtd by using component driver name on snd_soc_rtdcom_lookup(). Here, the reason why it uses "driver name" is that "component name" was created by fmt_single_name() and difficult to use it from driver. Driver of course knows its "driver name", thus, using it is more easy.

Sometimes DMI fields may be invalid and so can't give useful vendor, product or board info, such as "Type2 - Board Manufacturer" or "Type1 - TBD by OEM". Including such invalid DMI fileds may create silly card long name. So this patch creates a black list of invalid strings. And if a DMI field contains any string in this list, it will be excluded from the card long name.

ALSA SoC needs to know connected DAI ID for detecting. It is not a big problem if device/driver was only for sound, but getting DAI ID will be difficult if device includes both Video/Sound, like HDMI. To solve this issue, this patch adds new snd_soc_get_dai_id() and its related .of_xlate_dai_id callback on component driver. In below case, we can handle Sound port (= port@2) as ID = 0 if .of_xlate_dai_id has its support. hdmi { port@0 { /* VIDEO */ }; port@1 { /* VIDEO */ }; port@2 { /* SOUND */ }; }; Signed-off-by: NKuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: NMark Brown <broonie@kernel.org>

soc_cleanup_card_resources() call snd_card_free() at the last of its procedure. This turned out to lead to a use-after-free. PCM runtimes have been already removed via soc_remove_pcm_runtimes(), while it's dereferenced later in soc_pcm_free() called via snd_card_free(). The fix is simple: just move the snd_card_free() call to the beginning of the whole procedure. This also gives another benefit: it guarantees that all operations have been shut down before actually releasing the resources, which was racy until now.

Since recently UCM can pick up a configuration specific to the board via card longname field, and we introduced a helper function snd_soc_set_dmi_name() for that. So far, it was used only in one place (sound/soc/intel/boards/broadwell.c), but it should be more widely applied. This patch puts a big hammer for that: it lets snd_soc_register_card() calling snd_soc_set_dmi_name() unconditionally, so that all x86 devices get the better longname string. This would have no impact for other systems without DMI support, as snd_soc_set_dmi_name() is no-op on them.

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.

commit 1a653aa4 ("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 d2e3a135 ("ASoC: Fix binding and probing of auxiliary..."). One of main purpose of commit 1a653aa4 ("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 1a653aa4 ("ASoC: core: replace aux_comp_list to ...") and commit d2e3a135 ("ASoC: Fix binding and probing of auxiliary...").

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.
