Commit 2dc98af6 ("ASoC: max98090: fix lockdep warning") introduced a helpful-less small lock: shdn_lock. Reverts the commit. Reasons: 1. Lockdep should not be happy by either the original or current code. From lockdep's point of view, there is a lock inversion anyway. Let d = dapm_mutex, c = controls_rwsem, s = shdn_lock, From the reported calling stack: lock acquisition order of snd_soc_register_card() is: d -> c. > 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 If calling snd_soc_dapm_put_enum_double() in kcontrol's put (e.g. SOC_DAPM_ENUM_EXT), lock acquisition order is: c -> d. Note that, snd_soc_dapm_put_enum_double() acquires d. The possible lock inversion is always there if registering sound card and putting mixer control happen at the same time. In fact, it never happens because the control device don't show up to the userspace until the sound card build success. Commit 2dc98af6 ("ASoC: max98090: fix lockdep warning") changes the order to: c -> s -> d. The lock inversion is still there. 2. Commit 62d5ae4c ("ASoC: max98090: save and restore SHDN when changing sensitive registers SHDN bit") designed to use dapm_mutex to protect SHDN bit. Use a separate lock breaks the protection. DAPM changes SHDN bit automatically when it finds the path. Thus, any code wants to change the SHDN bit, need to acquire the dapm_mutex first. > SND_SOC_DAPM_SUPPLY("SHDN", M98090_REG_DEVICE_SHUTDOWN, > M98090_SHDNN_SHIFT, 0, NULL, 0), Fixes: 2dc98af6 ("ASoC: max98090: fix lockdep warning") Signed-off-by: Tzung-Bi Shih <tzungbi@google.com> Link: https://lore.kernel.org/r/20200117073814.82441-2-tzungbi@google.comSigned-off-by: Mark Brown <broonie@kernel.org>

Now, snd_soc_dai_driver::bus_control is used for how to resume. But, no driver which has bus_control has DAI driver suspend/resume support. This patch removes pointless bus_control from ALSA SoC.

Historically, CPU and Codec were implemented different, but now it is merged as Component. ALSA SoC is supporting suspend/resume at DAI and Component level. The method is like below. 1) Suspend/Resume all CPU DAI if bus-control was 0 2) Suspend/Resume all Component 3) Suspend/Resume all CPU DAI if bus-control was 1 Historically 2) was Codec special operation. Because CPU and Codec were merged into Component, CPU suspend/resume has 3 chance to suspend(= 1/2/3), but Codec suspend/resume has 1 chance (= 2). Here, DAI side suspend/resume is caring bus-control, but no driver which is supporting suspend/resume is setting bus-control. This means 3) was never used. Here, used parameter for suspend/resume component->dev and dai->dev are same pointer. For that reason, we can merge DAI and Component suspend/resume. One note is that we should use 2), because it is caring BIAS level. This patch removes 1) and 3).

There is no big difference at implementation for .suspend/.resume between DAI driver and Component driver. But because some driver is using DAI version, thus ALSA SoC needs to keep supporting it, hence, framework becoming verbose. If we can switch all DAI driver .suspend/.resume to Component driver, we can remove verbose code from ALSA SoC. Driver is getting its private data via dai->dev. But dai->dev and component->dev are same dev, thus, we can convert these. For same reason, we can convert dai->active to component->active if necessary.

PM8916 has three TX inputs that each have an (optional) internal RBIAS resistor. MIC BIAS Internal1/2 (for TX1/2) are already supported. TX3 does not have its own MIC BIAS supply, instead it is also supplied from MIC_BIAS1. Now that we have simplified the MIC BIAS Internal* implementation we can easily add support for it: Add a MIC BIAS Internal3 supply that enables the internal RBIAS resistor on TX3, and make sure to also enable the MIC_BIAS1 supply.

At the moment, MIC BIAS Internal* and MIC BIAS External* both reference the same register, and have a part of their initialization sequence duplicated. For example, the sequence for enabling MIC BIAS Internal1 is: I1. Enable MIC_BIAS1 supply (MICB_EN bit in CDC_A_MICB_1_EN) I2. Enable internal RBIAS (TX1_INT_RBIAS_EN bit in CDC_A_MICB_1_INT_RBIAS) The sequence for enabling MIC BIAS External1 is: E1. Enable MIC_BIAS1 supply (MICB_EN bit in CDC_A_MICB_1_EN) (E2. Ideally, make sure internal RBIAS is disabled. However, this should not happen in practice because DAPM will disable unused supplies...) Right now we have: SND_SOC_DAPM_SUPPLY("MIC BIAS Internal1", CDC_A_MICB_1_EN, 7, 0, ...) // I1 SND_SOC_DAPM_SUPPLY("MIC BIAS External1", CDC_A_MICB_1_EN, 7, 0, ...) // E1 and I2 is done in the PM event handler (pm8916_wcd_analog_enable_micbias_int1). We can simplify this by defining a common DAPM supply for I1/E1 ("MIC_BIAS1"), and one DAPM supply for I2 ("MIC BIAS Internal1"). Additional DAPM routes ensure that we also enable the MIC_BIAS1 supply for the internal and external pull up resistor. Another advantage of this is that we now disable the internal RBIAS when it is not needed. This makes it much easier to add support for MIC BIAS Internal3 as a next step.

ASoC: Fixes for v5.5 This is mostly driver specific fixes, plus an error handling fix in the core. There is a rather large diffstat for the stm32 SAI driver, this is a very large but mostly mechanical update which wraps every register access in the driver to allow a fix to the locking which avoids circular locks, the active change is much smaller and more reasonably sized.

Support multiple endpoints on SGTL5000 codec port when used in of_graph context. This patch allows to share the codec port between two CPU DAIs. Example: Custom STM32MP157C board uses SGTL5000 audio codec. This codec is connected to two serial audio interfaces, which are configured either as rx or tx. From AsoC point of view the topolgy is the following: // 2 CPU DAIs (SAI2A/B), 1 Codec (SGTL5000) Playback: CPU-A-DAI(slave) -> (master)CODEC-DAI/port0 Record: CPU-B-DAI(slave) <- (master)CODEC-DAI/port0 In the DT two endpoints have to be associated to the codec port: sgtl5000_port: port { sgtl5000_tx_endpoint: endpoint@0 { remote-endpoint = <&sai2a_endpoint>; }; sgtl5000_rx_endpoint: endpoint@1 { remote-endpoint = <&sai2b_endpoint>; }; }; However, when the audio graph card parses the codec nodes, it expects to find DAI interface indexes matching the endpoints indexes. The current patch forces the use of DAI id 0 for both endpoints, which allows to share the codec DAI between the two CPU DAIs for playback and capture streams respectively.

There are two asrc module in imx8qm & imx8qxp, each module has different clock configuration, and the DMA type is EDMA. So in this patch, we define the new clocks, refine the clock map, and include struct fsl_asrc_soc_data for different soc usage. The EDMA channel is fixed with each dma request, one dma request corresponding to one dma channel. So we need to request dma channel with dma request of asrc module.

Add compatible string "fsl,imx8qm-asrc" for imx8qm platform, "fsl,imx8qxp-asrc" for imx8qxp platform. There are two asrc modules in imx8qm & imx8qxp, the clock mapping is different for each other, so add new property "fsl,asrc-clk-map" to distinguish them.

Comparing the voltage of VDDA and VDDIO to determine whether or not to enable VDDC manual override is insufficient. This is a problem in case the VDDA is supplied from different regulator than VDDIO, while both report the same voltage to the regulator framework. In that case where VDDA and VDDIO is supplied by different regulators, the VDDC manual override must not be applied.

Add regulator_is_equal() helper to compare whether two regulators are the same. This is useful for checking whether two separate regulators in a driver are actually the same supply.
