ALSA SoC has some duplicate parameter. snd_soc_component::dai_drv is one of them. Each DAI is keeping its driver as snd_soc_dai::driver, and component has dai_list. This means, we can reach to each DAI and its driver by using dai_link. Thus, there is no need to keep DAI driver pointer on component. Let's remove it Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>

Codec will be replaced into Component, then Codec side doesn't use legacy_dai_naming on snd_soc_register_dais(). This patch adds new non_legacy_dai_naming flag on Component driver and use converted its value for snd_soc_register_dais(). When Codec is replaced into Component, Codec driver needs to have non_legacy_dai_naming = 1 flags. Existing CPU side of course doesn't have this flag, thus CPU calls it as true.

Codec will be replaced into Component, then Codec side only needs to call fixup_codec_formats() at this point. This patch adds new endianness flag on Component driver and call convert_endianness_formats() (= was fixup_codec_format()) if endianness was true. When Codec is replaced into Component, Codec driver needs to have endianness = 1 flags. Existing CPU side of course doesn't have this flag, thus CPU doesn't call it.

ALSA SoC platform/codec will be replaced to component soon. This means 1 device might have multiple components. But current unregister component function only checks "dev" to find it. This means, unexpected component might be unregistered by current function. But, it is no problem if driver registered only 1 component. To prepare avoid this issue, this patch adds new component lookup function. it finds component by "dev" and "driver name". 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. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>

In current ALSA SoC, Codec only has set_bias_level feature. Codec will be merged into Component in next generation ALSA SoC, thus current Codec specific feature need to be merged into it. This is glue patch for it. Codec driver has .idle_bias_off for dapm bias. But Component driver doesn't have it, and dapm->idle_bias_off is set as "true". To keep compatibility, this patch adds "idle_bias_on" instead of ".idle_bias_off" on Component driver. dapm->idle_bias_off will be set by inverted idle_bias_on. When we replace Codec to Component, the driver which has ".idle_bias_off = true" is just remove it, and the driver which doesn't have it will have new ".idle_bias_on = true".

Currently we're taking power_lock at each card component for assuring the power-up sequence, but it doesn't help anything in the implementation at the moment: it just serializes unnecessarily the callers, but it doesn't protect about the power state change itself. It used to have some usefulness in the early days where we managed the PM manually. But now the suspend/resume core procedure is beyond our hands, and power_lock lost its meaning. This patch drops the power_lock from allover the places. There shouldn't be any issues by this change, as it's no helper regarding the power state change. Rather we'll get better performance by removing the serialization; which is the only slight concern of any behavior change, but it can't be a showstopper, after all.

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.

Fix inconsistent use of of_graph_get_port_parent() where asoc_simple_card_parse_graph_dai() does of_node_get() before calling it while other callers do not. We can fix this by not trashing the node passed to of_graph_get_port_parent(). Let's also make sure the callers have correct refcounts and remove related incorrect of_node_put() calls for of_for_each_phandle as that's done by of_phandle_iterator_next() except when we break out of the loop early. Let's fix both issues with a single patch to avoid kobject refcounts getting messed up more if two patches are merged separately. Otherwise strange issues can happen caused by memory corruption caused by too many kobject_del() calls such as: BUG: sleeping function called from invalid context at kernel/locking/mutex.c:747 ...

This reverts commit 99b04f4c ("ASoC: add Component level pcm_new/pcm_free"), which started calling the pcm_new callback for every component in a *card* when creating a new pcm, something which does not seem to make any sense. This specifically led to memory leaks in systems with more than one platform component and where DMA memory is allocated in the platform-driver callback. For example, when both mcasp devices are being used on an am335x board, DMA memory would be allocated twice for every DAI link during probe. When CONFIG_SND_VERBOSE_PROCFS was set this fortunately also led to warnings such as: WARNING: CPU: 0 PID: 565 at ../fs/proc/generic.c:346 proc_register+0x110/0x154 proc_dir_entry 'sub0/prealloc' already registered Since there seems to be no users of the new component callbacks, and the current implementation introduced a regression, let's revert the offending commit for now.

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: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark 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.
