We have newer renoir platforms with different codecs combinations. Add struct in legacy machine driver and add to list of supported renoir machine to support sound card registration on platform with rt5682s as primary headset codec and max98360 and rt1019 as speaker amp codec. This also fixes error reported by kernel robot: "error: 'EN_SPKR_GPIO_DW' undeclared here" Reported-by:

The sc7280 driver really does depend on SOUNDWIRE since it calls various sdw_ functions (eg, sdw_enable_stream(), sdw_prepare_stream()) which do not have stubs when that is disabled so we can't build with COMPILE_TEST. Signed-off-by:

Normally, the clock source of audio module is either 26M or APLL1/APLL2, but APLL1/APLL2 are not the multiple of 26M. In the patch, APLL1 and APLL2 tuners are enabled to handle sample rate mismatch when the data path crosses two different clock domains. Signed-off-by:

There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use "flexible array members"[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. This helps with the ongoing efforts to globally enable -Warray-bounds and get us closer to being able to tighten the FORTIFY_SOURCE routines on memcpy().

On a platform shutdown, the expectation for most drivers is that userspace tasks will release all resources. When those sequences do not complete, it can be the case that PCM devices exposed by ALSA cards are used *after* the DSP shutdown completes, leading to a platform hang. When the clients and machine drivers provide an _unregister callback, let's invoke it in the shutdown sequence. Signed-off-by:

In the case like dmaengine which's not a dai but as a component, the num_dai is zero, dmaengine component has the same component_of_node as cpu dai, when cpu dai component is not ready, but dmaengine component is ready, try to get cpu dai name, the snd_soc_get_dai_name() return -EINVAL, not -EPROBE_DEFER, that cause below error: asoc-simple-card <card name>: parse error -22 asoc-simple-card: probe of <card name> failed with error -22 The sound card failed to probe. So this patch fixes the issue above by skipping the zero num_dai component in searching dai name. Signed-off-by:

On BIAS STANDBY->OFF transition the current implementation sleeps 600ms on suspend in order to discharge the chip. The suspend is propagated from "snd_soc_suspend" call for all audio cards in a serial fashion, thus in case of boards like i.MX8DXL EVK which has 3 distinct WM8960 codecs the total cumulated sleep on suspend is 1.8 seconds. On the other hand the BIAS OFF->STANDBY transition happens asynchronously with regard to "snd_soc_resume" - the call is propagated from "soc_resume_deferred" which is just scheduled from "snd_soc_resume", each card having its own work scheduled to execute "soc_resume_deferred" call. The patch performs discharge completion on BIAS OFF->STANDBY transition so that the cumulated effect on suspend described above is avoided and discharge is completed in paralel in case of multiple WM8960 codecs on the board.

When checking if the requested parameters are supported, the driver uses PCM3168A_FMT_DSP_MASK to check for PCM3168A_FMT_DSP_* values. However, formally not only PCM3168A_FMT_DSP_* values match that condition, PCM3168A_FMT_I2S_TDM and PCM3168A_FMT_LEFT_J_TDM also do. The check still gives correct result because those extra values can't be in 'fmt' at the check location. Still, to make the code less cryptic, better to compare 'fmt' with PCM3168A_FMT_DSP_* values explicitly. Signed-off-by:

Newer firmwares will support compressed buffers that may or may not exist, for example debugging streams. Update the driver to make a compressed stream optional. A warning will still be generated at DSP boot time and opening the stream will fail if the compressed buffer in question does not exist, however the DSP can still be booted and other features used.

The TLV320ADC3001/3101 have an internal DSP, which can either be used in various preset configurations (called "Processing Blocks" in the data sheet), or as a freely programmable (using the "PurePath Studio" graphical programming tool from TI) but rather small DSP ("miniDSP"). Using the default configuration (PRB_R1) it's possible to set up filtering using a first-order IIR, which can be useful for adding a digital high pass filter to the signal chain, for instance. This patch adds support for configuring the IIR filter coefficients. The filter itself is always enabled; the default coefficients implement a pass-through function.

Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>: The Linux SOF implementation is historically monolithic in a sense that all features accessible in the firmware can be used via the snd_sof_dev struct in one way or another. Support for features can not be added or removed runtime and with the current way of things it is hard if not impossible to implement support for dynamic feature support when based on the firmware manifest we can easily enable/access independent modules with the SOF. In order to be able to support such modularity this series introduces a small framework within SOF for client support using the Auxiliary bus. Client drivers can be removed runtime and later re-loaded if needed without affecting the core's behaviour, but it is the core's and the platform's duty to create the Auxiliary devices usable in the platform and via the firmware. There is still a need for SOF manifest update to convey information about features to really make the full dynamic client device creation. The series will introduce the core SOF client support and converts the generic ipc flood test, ipc message injector and the probes (Intel HDA only) to a client driver.
