McBSP is able to drive bit clock and consume frame clock but BP_FC format is not handled by McBSP driver. Add BP_FC format support. When BP_FC is selected: - CLKX and CLKR are configured as outputs - The sample rate generator is configured to be able to provide bit clock.

TDM is not supported by the McBSP driver. The McBSP datasheet does not name explicitly TDM as a supported format but it is possible to configure the McBSP to do TDM if all slots are used by McBSP. Add TDM support. It uses single-phase frame. Slot width is used to compute the McBSP's word length. Implement the set_tdm_slot() hook of snd_soc_dai_ops struct. It only supports TDM if all slots are used by McBSP. The snd_soc_dai_driver's channels_max is updated from 2 to 128. This was tested with BP_FC format on a platform designed off of DAVINCI/OMAP_L138. A check is done in davinci_i2s_set_dai_fmt() to prevent TDM to be used with BC_FC and BC_FP formats. Signed-off-by:

McBSP's internal sample rate generator can be programed to be driven by its internal clock or by an external clock source located on CLKS pin. The external clock source case is not handled by the driver. Handle an optional clock related to this external clock source. If present, the driver uses the clock located on CLKS pin as input for the sample rate generator. Thus, the external clock rate is used to compute divisors. If this optional clock is not present, the sample rate generator is driven by the McBSP's functional clock. Signed-off-by:

The clk_input_pin attribute of davinci_mcbsp_dev struct is not set since commit 257ade78 ("ASoC: davinci-i2s: Convert to use edma-pcm"). Remove the attribute. Keep the behaviour of the MCBSP_CLKR case as MCBSP_CLKR == 0. I can't test the BC_FP format so I added back the initial comment that was removed by commit ec637553 ("ASoC: DaVinci: Added selection of clk input pin for McBSP"). This was the last dependency to linux/platform_data/davinci_asp.h so it is not included anymore. Remove the enum mcbsp_clk_input_pin from davinci_asp.h as it is not used anywhere else. Signed-off-by:

The McBSP uses an internal sample rate generator to provide bit clock or frame clock. This sample rate generator can be programmed to be driven by McBSP's internal clock source or by an external clock source (located on CLKS pin). The external clock source is not described in the bindings. Add an optional clock item that allows to select an external clock as sample rate generator's input. Signed-off-by:

Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>: For LunarLake, the SoundWire in-band wake detection is reported with the HDAudio WAKE_EN/WAKE_STS registers. In the existing code, these registers are only handled for HDaudio codecs. Now the same registers have to be handled with care as shared resources. The in-band wake detection mainly used for jack detection. Without this patchset, the SoundWire headset codecs signal an event that would be ignored and not reported.

Merge series from Cezary Rojewski <cezary.rojewski@intel.com>: Set of changes targeting the avs-driver only. No new features, patchset either fixes or fortifies existing code.

While HDAudio controller supports buffer packets up to 128 bytes low, audio format shall be taken into consideration when calculating buffer and period sizes to avoid undesired xruns. As *_size in ALSA terms means frames (channels times bit-depth-bytes), hw_rules can calculate minimal buffer and period sizes solely from sample rate and the number of milliseconds commonly used on the AudioDSP firmware side.

When a PME wake happens due to a SoundWire wake, we currently clear all WAKESTS bits during the resume operation initiated by the PCI subsystem. As a result, we are unable to identify which SoundWire links need to be resumed and don't properly handle jack detection. This patch only clears the WAKESTS bits for the HDaudio codecs detected earlier. Note that we still clear all WAKESTS bits unconditionally in hda_dsp_ctrl_stop_chip(). The existing behavior is potentially racy if e.g. a jack event happens during a suspend routine, but there's a risk of breaking shutdown or reboot sequences so the code is left as is for now.

Since LunarLake, we use the HDadio WAKEEN/WAKESTS to detect wakes for SoundWire codecs. Unfortunately, the existing code in hda_codec_jack_wake_enable() unconditionally resets the WAKEEN bits. This patch changes the initialization to preserve SoundWire WAKEEN bits. For HDAudio codecs the same strategy is used, WAKEEN is only set when the jacktbl.used property is set.

For some reason, the programming sequences in the SOF driver do not include a clear of the WAKE_STS bits before resetting the controller. This clear is not formally required by the HDaudio specification, but was added to harden the snd-hda-reset back in 2007. Adding this sequence back avoids an issue reported by the Intel CI.

The HDaudio stream interrupts are ignored unless the stream is PCM or compressed audio. For alternate non-audio usages, such as code loader or SoundWire BPT case, the IOC interrupt on the last buffer transferred is silently ignored. This patch adds a 'struct completion' for each HDaudio stream. This capability helps detect if the non-audio data transfers completed. There is no performance impact for audio streams. In the code loader case, the code currently starts the DMA and directly checks if the firmware status changes, without checking if the DMA succeeded. With a first pass waiting for the DMA to complete, system validation engineers can gather more precise timing information on firmware boot time or root-cause boot failures more accurately. A timeout of 500ms was selected for the code loader DMA. This is an experimental value which should be more than enough - higher values would certainly be problematic from a usage/latency perspective. Signed-off-by:

We need to reuse cl_prepare, cl_trigger and cl_cleanup helpers from a SoundWire context where only the device information is available. Rather than pass the 'sdev' argument, use get_drvdata() to retrieve the required structure. For consistency, rename hda_cl_stream_prepare() as hda_cl_prepare(). These three helpers are also exported so that they can be referenced from another module. Signed-off-by:
