ALSA SoC need to care pinctrl_pm_select_xxx(). It is called at soc-core and soc-pcm. soc-pcm is controlling it for activate DAI. soc-core is controlling it for whole system (= suspend/resume/probe/poweroff). If we focus to soc-core side, it need to care about BIAS level. Then, snd_soc_suspend() only is controlling it by Component base (a). Other functions are DAI base (b). (a) pinctrl_pm_select_xxx(component->dev, xxx); (b) pinctrl_pm_select_xxx(dai->dev, xxx); Because of these unbalance, the code is confusable. Here, dai->dev and component->dev are same pointer. Thus, we can replace it component base. One note here is that it cared DAI (= CPU/Codec) pin before this patch, after this patch, it cares Component (= CPU/Codec/Platform) pin. Signed-off-by:

snd_soc_suspend() are doing below for pinctrl_pm_select_sleep_state() int snd_soc_suspend(struct device *dev) { ... for_each_card_components(card, component) { ... (1) pinctrl_pm_select_sleep_state(component->dev); } for_each_card_rtds(card, rtd) { ... (2) pinctrl_pm_select_sleep_state(cpu_dai->dev); } } (1) is called for all component (CPU/Codec/Platform), and (2) is called for CPU DAIs. Here, component->dev is same as dai->dev. This means, it is called in duplicate on CPU case. This patch removes (2). Signed-off-by: -

Card dai_link has .ignore_suspend, and ALSA SoC cares it when suspend. For example, like this for_each_card_rtds(card, rtd) { if (rtd->dai_link->ignore_suspend) continue; ... } But in snd_soc_suspend(), it doesn't care about it when suspending Component. This patch cares it. Signed-off-by: -

Current ALSA SoC is using struct snd_soc_rtdcom_list to connecting component to rtd by using list_head. struct snd_soc_rtdcom_list { struct snd_soc_component *component; struct list_head list; /* rtd::component_list */ }; struct snd_soc_pcm_runtime { ... struct list_head component_list; /* list of connected components */ ... }; The CPU/Codec/Platform component which will be connected to rtd (a) is indicated via dai_link at snd_soc_add_pcm_runtime() int snd_soc_add_pcm_runtime(...) { ... /* Find CPU from registered CPUs */ rtd->cpu_dai = snd_soc_find_dai(dai_link->cpus); ... (a) snd_soc_rtdcom_add(rtd, rtd->cpu_dai->component); ... /* Find CODEC from registered CODECs */ (b) for_each_link_codecs(dai_link, i, codec) { rtd->codec_dais[i] = snd_soc_find_dai(codec); ... (a) snd_soc_rtdcom_add(rtd, rtd->codec_dais[i]->component); } ... /* Find PLATFORM from registered PLATFORMs */ (b) for_each_link_platforms(dai_link, i, platform) { for_each_component(component) { ... (a) snd_soc_rtdcom_add(rtd, component); } } } It shows, it is possible to know how many components will be connected to rtd by using dai_link->num_cpus dai_link->num_codecs dai_link->num_platforms If so, we can use component pointer array instead of list_head, in such case, code can be more simple. This patch removes struct snd_soc_rtdcom_list that is only of temporary value, and convert to pointer array. Signed-off-by: -

In current driver, locks can be taken as follows: - Register access: take a lock on regmap config and then on clock. - Master clock provider: take a lock on clock and then on regmap config. This can lead to the circular locking summarized below. Remove peripheral clock management through regmap framework, and manage peripheral clock in driver instead. On register access, lock on clock is taken first, which allows to avoid possible locking issue.

Commit 62d5ae4c ("ASoC: max98090: save and restore SHDN when changing sensitive registers") extended the code for handling many controls by adding a custom put function to them. That new custom put function properly handles relations between codec's hardware registers. However they used card->dapm_mutex to properly serialize those operations. This in turn triggers a lockdep warning about possible circular dependency. Fix this by introducing a separate mutex only for serializing the SHDN hardware register related operations. This fixes the following lockdep warning observed on Exynos4412-based Odroid U3 board: ====================================================== WARNING: possible circular locking dependency detected 5.5.0-rc5-next-20200107 #166 Not tainted ------------------------------------------------------ alsactl/1104 is trying to acquire lock: ed0d50f4 (&card->dapm_mutex){+.+.}, at: max98090_shdn_save+0x1c/0x28 but task is already holding lock: edb4b49c (&card->controls_rwsem){++++}, at: snd_ctl_ioctl+0xcc/0xbb8 which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #1 (&card->controls_rwsem){++++}: snd_ctl_add_replace+0x3c/0x84 dapm_create_or_share_kcontrol+0x24c/0x2e0 snd_soc_dapm_new_widgets+0x308/0x594 snd_soc_bind_card+0x80c/0xad4 devm_snd_soc_register_card+0x34/0x6c odroid_audio_probe+0x288/0x34c platform_drv_probe+0x6c/0xa4 really_probe+0x200/0x490 driver_probe_device+0x78/0x1f8 bus_for_each_drv+0x74/0xb8 __device_attach+0xd4/0x16c bus_probe_device+0x88/0x90 deferred_probe_work_func+0x3c/0xd0 process_one_work+0x22c/0x7c4 worker_thread+0x44/0x524 kthread+0x130/0x164 ret_from_fork+0x14/0x20 0x0 -> #0 (&card->dapm_mutex){+.+.}: lock_acquire+0xe8/0x270 __mutex_lock+0x9c/0xb18 mutex_lock_nested+0x1c/0x24 max98090_shdn_save+0x1c/0x28 max98090_put_enum_double+0x20/0x40 snd_ctl_ioctl+0x190/0xbb8 ksys_ioctl+0x470/0xaf8 ret_fast_syscall+0x0/0x28 0xbefaa564 other info that might help us debug this: Possible unsafe locking scenario: CPU0 CPU1 ---- ---- lock(&card->controls_rwsem); lock(&card->dapm_mutex); lock(&card->controls_rwsem); lock(&card->dapm_mutex); *** DEADLOCK *** 1 lock held by alsactl/1104: #0: edb4b49c (&card->controls_rwsem){++++}, at: snd_ctl_ioctl+0xcc/0xbb8 stack backtrace: CPU: 0 PID: 1104 Comm: alsactl Not tainted 5.5.0-rc5-next-20200107 #166 Hardware name: SAMSUNG EXYNOS (Flattened Device Tree) (unwind_backtrace) from [<c010e180>] (show_stack+0x10/0x14) (show_stack) from [<c0b2a09c>] (dump_stack+0xb4/0xe0) (dump_stack) from [<c018a1c0>] (check_noncircular+0x1ec/0x208) (check_noncircular) from [<c018c5dc>] (__lock_acquire+0x1210/0x25ec) (__lock_acquire) from [<c018e2d8>] (lock_acquire+0xe8/0x270) (lock_acquire) from [<c0b49678>] (__mutex_lock+0x9c/0xb18) (__mutex_lock) from [<c0b4a110>] (mutex_lock_nested+0x1c/0x24) (mutex_lock_nested) from [<c0839b3c>] (max98090_shdn_save+0x1c/0x28) (max98090_shdn_save) from [<c083a5b8>] (max98090_put_enum_double+0x20/0x40) (max98090_put_enum_double) from [<c080d0e8>] (snd_ctl_ioctl+0x190/0xbb8) (snd_ctl_ioctl) from [<c02cafec>] (ksys_ioctl+0x470/0xaf8) (ksys_ioctl) from [<c0101000>] (ret_fast_syscall+0x0/0x28) ...

Since ApolloLake, Intel platforms require signed firmware. On all Windows platforms the default is to require the Intel production key be used. But some platforms allow for a community key to be used, which allows developers to compile/build their own firmware. In the linux-firmware tree, the default intel/sof path is used for firmwares signed for the production key, and files signed with the community key are located in intel/sof/community. Since we don't have an API to query which key is used on what platforms, we have to rely on DMI-based quirks. Developers can bypass this mechanism by setting a kernel 'fw_path' module parameter. Additional dynamic debug traces are provided to help debug cases where the wrong file might be used. Signed-off-by:

Some members of the Google_Hatch family include a rt5682 jack codec, but no speaker amplifier. This uses the same driver (sof_rt5682) as a combination of rt5682 jack codec and max98357a speaker amplifier. Within the sof_rt5682 driver, these cases are not currently distinguishable, relying on a DMI quirk to decide the configuration. This causes an incorrect configuration when only the rt5682 is present on a Google_Hatch device. For CML, the jack codec is used as the primary key when matching, with a possible speaker amplifier described in quirk_data. The two cases of interest are the second and third 10EC5682 entries in snd_soc_acpi_intel_cml_machines[]. The second entry matches the combination of rt5682 and max98357a, resulting in the quirk_data field in the snd_soc_acpi_mach being non-null, pointing at max98357a_spk_codecs, the snd_soc_acpi_codecs for the matched speaker amplifier. The third entry matches just the rt5682, resulting in a null quirk_data. The sof_rt5682 driver's DMI data matching identifies that a speaker amplifier is present for all Google_Hatch family devices. Detect cases where there is no speaker amplifier by checking for a null quirk_data in the snd_soc_acpi_mach and remove the speaker amplifier bit in that case. Signed-off-by:
