Current rsnd sets "channels_min" which is used from snd_soc_dai_stream_valid() without checking DT playback/capture property. Thus, "aplay -l" or "arecord -l" will indicate un-exising device. This patch checks DT proerty and do nothing playback/capture settings if not exist. Signed-off-by:

Merge series from Stefan Binding <sbinding@opensource.cirrus.com>: The CS42L42 has a SoundWire interface for control and audio. This chain of patches adds support for this. Patches #1 .. #5 split out various changes to the existing code that are needed for adding Soundwire. These are mostly around clocking and supporting the separate probe and enumeration stages in SoundWire. Patches #6 .. #8 actually adds the SoundWire handling.

Merge series from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>: struct snd_soc_dai need to have info for playback/capture, but it is using "playback/capture_xxx" or "tx/tx_xxx" or array. This kind of random definition is very difficult to read. This patch-set add helper functions and each driver use it. And cleanup the definition.

Since clock stop causes bus reset on Intel controllers, we need to wait for the debounce interval on resume, to ensure all the interrupt status registers are set correctly. Signed-off-by:

idle_bias_on was set because cs42l42 has a "VMID" type pseudo-midrail supply (named FILT+), and these typically take a long time to charge. But the driver never enabled pm_runtime so it would never have powered- down the cs42l42 anyway. In fact, FILT+ can charge to operating voltage within 12.5 milliseconds of enabling HP or ADC. This time is already covered by the startup delay of the HP/ADC. The datasheet warning about FILT+ taking up to 1 second to charge only applies in the special cases that either the PLL is started or DETECT_MODE set to non-zero while both HP and ADC are off. The driver never does either of these. Removing idle_bias_on allows the Soundwire host controller to suspend if there isn't a snd_soc_jack handler registered. Signed-off-by:

This adds support for using CS42L42 as a SoundWire device. SoundWire-specifics are kept separate from the I2S implementation as much as possible, aiming to limit the risk of breaking the I2C+I2S support. There are some important differences in the silicon behaviour between I2S and SoundWire mode that are reflected in the implementation: - ASP (I2S) most not be used in SoundWire mode because the two interfaces share pins. - The SoundWire capture (record) port only supports 1 channel. It does not have left-to-right duplication like the ASP. - DP2 can only be prepared if the HP has powered-up. DP1 can only be prepared if the ADC has powered-up. (This ordering restriction does not exist for ASPs.) The SoundWire core port-prepare step is triggered by the DAI-link prepare(). This happens before the codec DAI prepare() or the DAPM sequence so these cannot be used to enable HP/ADC. Instead the HP/ADC enable/disable are done during the port_prep callback. - The SRCs are an integral part of the audio chain but in silicon their power control is linked to the ASP. There is no equivalent power link to SoundWire DPs so the driver must take "manual" control of SRC power. - The SoundWire control registers occupy the lower part of the SoundWire address space so cs42l42 registers are offset by 0x8000 (non-paged) in SoundWire mode. - Register addresses are 8-bit paged in I2C mode but 16-bit unpaged in SoundWire. - Special procedures are needed on register read/writes to (a) ensure that the previous internal bus transaction has completed, and (b) handle delayed read results, when the read value could not be returned within the SoundWire read command. There are also some differences in driver implementation between I2S and SoundWire operation: - CS42L42 I2S does not runtime_suspend, but runtime_suspend/resume support has been added into the driver in SoundWire mode as the most convenient way to power-up the bus manager and to handle the unattach_request condition, though the CS42L42 chip does not itself suspend or resume. - Intel SoundWire host controllers have a low-power clock-stop mode that requires resetting all peripherals when resuming. This means that the interrupt registers will be reset in between the interrupt being generated and the interrupt being handled, and since the interrupt status is debounced, these values may not be accurate immediately, and may cause spurious unplug events before settling. - As in I2S mode, the PLL is only used while audio is active because of clocking quirks in the silicon. For SoundWire the cs42l42_pll_config() is deferred until the DAI prepare(), to allow the cs42l42_bus_config() callback to set the SCLK. Signed-off-by:

Setup of the ASP (audio serial port) was being done as a side-effect of cs42l42_pll_config() and forces a restriction on the ratio of sample_rate to bit_clock that is invalid for Soundwire. Move the ASP setup into a dedicated function. Signed-off-by:

The chosen clocking configuration must give an internal MCLK (MCLKint) that is an integer multiple of the sample rate. On I2S each of the supported bit clock frequencies can only be generated from one sample rate group (either the 44100 or the 48000) so the code could use only the bitclock to look up a PLL config. The relationship between sample rate and bitclock frequency is more complex on Soundwire and so it is possible to set a frame shape to generate a bitclock from the "wrong" group. For example 2*147 with a 48000 sample rate would give a bitclock of 14112000 which on I2S could only be derived from a 44100 sample rate. Signed-off-by:

Currently, port_prep callback only has commands for PRE_PREP, PREP, and POST_PREP, which doesn't directly say whether this is for a prepare or deprepare call. Extend the command list enum to say whether the call is for prepare or deprepare aswell. Also remove SDW_OPS_PORT_PREP from sdw_port_prep_ops as this is unused, and update this enum to be simpler and more consistent with enum sdw_clk_stop_type. Note: Currently, the only users of SDW_OPS_PORT_POST_PREP are codec drivers sound/soc/codecs/wsa881x.c and sound/soc/codecs/wsa883x.c, both of which seem to assume that POST_PREP only occurs after a prepare, even though it would also have occurred after a deprepare. Since it doesn't make sense to mark the port prepared after a deprepare, changing the enum to separate PORT_DEPREP from PORT_PREP should make the check for PORT_PREP in those drivers be more logical.

Current snd_soc_dai has data for Playback/Capture, but it is very random. Someone is array (A), someone is playback/capture (B), and someone is tx/rx (C); struct snd_soc_dai { ... (A) unsigned int stream_active[SNDRV_PCM_STREAM_LAST + 1]; (B) struct snd_soc_dapm_widget *playback_widget; (B) struct snd_soc_dapm_widget *capture_widget; (B) void *playback_dma_data; (B) void *capture_dma_data; ... (C) unsigned int tx_mask; (C) unsigned int rx_mask; }; Because of it, the code was very complicated. This patch creates new data structure to merge these into one, and tidyup the code.
