As sparse warns, the PCM format type can't be dealt as integer as found in Intel SST driver codes. Fix them in the following two ways: - The open code with snd_mask_set() and params->masks reference is replaced with params_set_format() - The rest codes with snd_mask_set(fmt, SNDRV_PCM_FORMAT_XXX) are replaced with the new helper, snd_mask_set_format().

The example code in dpcm.rst contains an open code calling snd_mask_set(), and this can be better represented with params_set_format() instead. This automatically fixes the sparse warning about snd_pcm_format_t handling, too. Signed-off-by:

Many drivers calling snd_mask_set() need to do ugly cast with __force for shutting up the sparse warnings. Actually almost all of them are about setting the format, so it's far better to provide a common helper snd_mask_set_format() to pass SNDRV_PCM_FORMAT_* directly without the cast. There are a few other calls of snd_mask_set(), but they are in the PCM core code, so we leave them for now. Signed-off-by:

This helps solve 0-day compilation issues when CONFIG_SND_DMA_SGBUF is not defined.

fmt in snd_soc_dai_link_event() contains the format bit position, not the format bit itself. Hence it can be a simple integer instead of the explicit u64. Signed-off-by:

It seems that __user prefix was forgotten to be added to dmaengine_copy_user callback while we refactored the user-copy PCM core. This patch adds the missing prefix, remove the superfluous cast, and add the needed cast (__force is needed for downgrading from user pointer to kernel pointer), too. Spotted by a sparse warning like: sound/soc/soc-generic-dmaengine-pcm.c:397:27: warning: incorrect type in initializer (incompatible argument 4 (different address spaces)) Signed-off-by:

zx-tdm driver sets the DAI driver definitions with the format bits wrongly set with SNDRV_PCM_FORMAT_*, instead of SNDRV_PCM_FMTBIT_*. This patch corrects the definitions.

Amlogic's axg card driver can't use snd_soc_of_parse_tdm_slot() directly because it needs to handle 4 mask for each direction. Yet the parsing of each mask is the same, so export snd_soc_of_get_slot_mask() to reuse the the existing code. Signed-off-by:

Add Amlogic's axg TDM interface driver. This driver manages the format and clocks provided on the pads. On this SoC, each stream direction provides 4 serial lanes. This makes a maximum of 8 channels in i2s modes and 128 channels in DSP modes. While each lanes operate on the same slot number (same bit clock), they may have different TDM masks. This requires to provide a function to let the card set the 4 masks, in lieu of the usual set_tdm_slots() callback of the dai driver. Signed-off-by:

Add Amlogic's axg TDM core driver. On this SoC, tdm is bit more complex than usual, mainly because the different TDM input decoders can be attached to any of TDM pad interface, including the output pads. For the this, TDM on this SoC is modeled like this: - TDM interface provides the DAIs the codecs will be attached to. The main responsibility of this driver is to manage the pad format and the TDM clock rates. - TDM Formatters: These are the entities which are actually dealing with the TDM signal. TDMOUT produce a TDM signal from the audio sample provided by FRDDR using the clocks provided the TDM interface. TDMIN feeds TODDR with audio sample using the clocks and TDM signal provided by the TDM Interface. - TDM Streams: This provides the link between 1 DAI stream of the TDM interface and one (or more) TDM formatters. This driver provides the TDM formatter and TDM stream operations. Signed-off-by:
