MIC BIAS Internal1 is broken at the moment because we always enable the internal rbias resistor to the TX2 line (connected to the headset microphone), rather than enabling the resistor connected to TX1. Move the RBIAS code to pm8916_wcd_analog_enable_micbias_int1/2() to fix this.

MIC BIAS External1 sets pm8916_wcd_analog_enable_micbias_ext1() as event handler, which ends up in pm8916_wcd_analog_enable_micbias_ext(). But pm8916_wcd_analog_enable_micbias_ext() only handles the POST_PMU event, which is not specified in the event flags for MIC BIAS External1. This means that the code in the event handler is never actually run. Set SND_SOC_DAPM_POST_PMU as the only event for the handler to fix this.

In case system has multiple HDA controllers, it can happen that same HDA codec driver is used for codecs of multiple controllers. In this case, SOF may fail to probe the HDA driver and SOF initialization fails. SOF HDA code currently relies that a call to request_module() will also run device matching logic to attach driver to the codec instance. However if driver for another HDA controller was already loaded and it already loaded the HDA codec driver, this breaks current logic in SOF. In this case the request_module() SOF does becomes a no-op and HDA Codec driver is not attached to the codec instance sitting on the HDA bus SOF is controlling. Typical scenario would be a system with both external and internal GPUs, with driver of the external GPU loaded first. Fix this by adding similar logic as is used in legacy HDA driver where an explicit device_attach() call is done after request_module(). Also add logic to propagate errors reported by device_attach() back to caller. This also works in the case where drivers are not built as modules.

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.

dsp_box is used to keep DSP initiated messages. The value of dsp_offset is set by the DSP with the first message, so we need a way to bootstrap it in order to get the first message. We do this by setting the correct default dsp_box offset which on i.MX8 is not zero. Very interesting is why it has worked until now. On i.MX8, DSP communicates with ARM core using a shared SDRAM memory area. Actually, there are two shared areas: * SDRAM0 - starting at 0x92400000, size 0x800000 * SDRAM1 - starting at 0x92C00000, size 0x800000 SDRAM0 keeps the data sections, starting with .rodata. By chance fw_ready structure was placed at the beginning of .rodata. dsp_box_base is defined as SDRAM0 + dsp_box_offset and it is placed at the beginning of SDRAM1 (dsp_box_offset should be 0x800000). But because it is zero initialized by default it points to SDRAM0 where by chance the fw_ready was placed in the SOF firmware. Anyhow, SOF commit 7466bee378dd811b ("clk: make freq arrays constant") fw_ready is no longer at the beginning of SDRAM0 and everything shows how lucky we were until now. Fix this by properly setting the default dsp_box offset.

The error path of soc_new_pcm_runtime() invokes soc_free_pcm_runtime() that may cause a few problems. First off, it calls list_del() for rtd->list that may not be initialized. Similarly, snd_soc_pcm_component_free() traverses over the component list that may not be initialized, either. Such access to the uninitialized list head would lead to either a BUG_ON() or a memory corruption. This patch fixes the access to uninitialized list heads by initializing the list heads properly at the beginning before those error paths.

When the PCM_PARAM IPC fails while configuring the FE, the kernel oopses in the HDaudio link DMA .hw_free operation. The root cause is a NULL dma_data since the BE .hw_params was never called by the SOC core. This error can also happen if the HDaudio link DMA configuration IPC fails in the BE .hw_params. This patches makes sure the dma_data is properly saved in .hw_params, and tested before being use in hw_free.

On CML boards with the RT5682 headset codec and RT1011 speaker amplifier, the platform firmware exposes three ACPI HIDs (10EC5682, 10EC1011 and MX98357A). The last HID is a mistake in DSDT tables, which causes the wrong machine driver to be loaded. This patch changes the key used to identify boards and changes the order of entries in the table to load the correct machine driver. The order does matter and should not be modified to work-around this firmware issue.

Adding a platform property to a link description like: simple-audio-card,dai-link { cpu { sound-dai = <&sai1>; }; plat { sound-dai = <&dsp>; }; codec { sound-dai = <&wm8960>; } will result in the creation of two links: * sai1 <-> wm8960 * dsp <-> wm8960 which is obviously not what we want. We just want one single link with: * sai1 <-> wm8960 (and platform set to dsp).

Because of that, the link will not get added into the card list, so any attempt to remove it later ends up in a panic. Fix that by checking the return status and free the memory in case of an error.

There are many paths to soc_free_pcm_runtime which can both have and have not yet inited the workqueue yet. When we flush the queue when we have not yet inited the queue we cause warnings to be printed. An example is soc_cleanup_card_resources which is called by snd_soc_bind_card which has multiple failure points before and after soc_link_init -> soc_new_pcm which is where the queue is inited.

When the Teclast X89 quirk was added we did not have jack-detection support yet. Note the over-current detection limit is set to 2mA instead of the usual 1.5mA because this tablet tends to give false-positive button-presses when it is set to 1.5mA.

There are cases where we fail before we reach soc_new_pcm which would init the workqueue. When we fail we attempt to flush the queue which generates warnings from the workqueue subsystem when we have not inited the queue. Solution is to use a proxy function to get around this issue.

max98090_interrupt() and max98090_pll_work() run in 2 different threads. There are 2 possible races: Note: M98090_REG_DEVICE_STATUS = 0x01. Note: ULK == 0, PLL is locked; ULK == 1, PLL is unlocked. max98090_interrupt max98090_pll_work ---------------------------------------------- schedule max98090_pll_work restart max98090 codec receive ULK INT assert ULK == 0 schedule max98090_pll_work (1). In the case (1), the PLL is locked but max98090_interrupt unnecessarily schedules another max98090_pll_work. max98090_interrupt max98090_pll_work max98090 codec ---------------------------------------------------------------------- ULK = 1 receive ULK INT read 0x01 ULK = 0 (clear on read) schedule max98090_pll_work restart max98090 codec ULK = 1 receive ULK INT read 0x01 ULK = 0 (clear on read) read 0x01 assert ULK == 0 (2). In the case (2), both max98090_interrupt and max98090_pll_work read the same clear-on-read register. max98090_pll_work would falsely thought PLL is locked. Note: the case (2) race is introduced by the previous commit ("ASoC: max98090: exit workaround earlier if PLL is locked") to check the status and exit the loop earlier in max98090_pll_work. There are 2 possible solution options: A. turn off ULK interrupt before scheduling max98090_pll_work; and turn on again before exiting max98090_pll_work. B. remove the second thread of execution. Option A cannot fix the case (2) race because it still has 2 threads access the same clear-on-read register simultaneously. Although we could suppose the register is volatile and read the status via I2C could be much slower than the hardware raises the bits. Option B introduces a maximum 10~12 msec penalty delay in the interrupt handler. However, it could only punish the jack detection by extra 10~12 msec. Adopts option B which is the better solution overall.

According to the datasheet, PLL lock time typically takes 2 msec and at most takes 7 msec. Check the lock status every 1 msec and exit the workaround if PLL is locked.

It was observed Baytrail-based chromebooks could cause continuous PLL unlocked when using playback stream and capture stream simultaneously. Specifically, starting a capture stream after started a playback stream. As a result, the audio data could corrupt or turn completely silent. As the datasheet suggested, the maximum PLL lock time should be 7 msec. The workaround resets the codec softly by toggling SHDN off and on if PLL failed to lock for 10 msec. Notably, there is no suggested hold time for SHDN off. On Baytrail-based chromebooks, it would easily happen continuous PLL unlocked if there is a 10 msec delay between SHDN off and on. Removes the msleep().

The simple-card tries to signal the codec to disable rate constraints, see commit 2458adb8 ("SoC: simple-card-utils: set 0Hz to sysclk when shutdown"). This wasn't handled by the codec, instead it would set the FLL frequency to 0Hz which isn't working. Since we don't have any rate constraints just ignore this request.
