ASoC: audio-graph-card2.c: remove pre-alloced Codec2Codec space

2022-07-08T10:51:43+00:00

Because Codec2Codec settings becomes optional, we don't need to keep its parameter space when init time. This patch removes its default memory allocation from simple-card-utils.c, and allocate it at audio-graph-card2 ondemand.

ASoC: simple-card-utils: Make asoc_simple_clean_reference() return void

2022-06-07T11:00:43+00:00

asoc_simple_clean_reference() returns zero unconditionally. Letting it return void instead makes it easier to see in the caller that there is no error to handle. This is a preparation for making platform remove callbacks return void.

ASoC: audio_graph_card2: Add support for variable slot widths

2022-03-07T13:12:58+00:00

Some audio hardware cannot support the same slot width for all sample widths, or a slot width equal to the sample width for all sample widths. This is usually due either to limitations of the audio serial port or system clocking restrictions. A typical example would be: - 16-bit samples in 16-bit slots - 24-bit samples in 32-bit slots The new dai-tdm-slot-width-map property allows setting a mapping of sample widths and the corresponding tdm slot widths and slot counts. Although the slot count is usually the same for all cases this does allow for adding padding slots to maintain the same bitclk frequency. The property is added to each endpoint node that needs the component DAI to be told the TDM slot width and count.

ASoC: simple-card-utils: Add new system-clock-fixed flag

2022-01-24T19:45:43+00:00

Add a new system-clock-fixed flag, which can be used to specify that the driver cannot or should not allow the clock frequency of the mapped clock to be modified. This behavior is also implied if the system-clock-frequency parameter is set explicitly - the flag is meant for cases where a clock is mapped to the DAI but which is, or should be treated as, fixed. When mclk-fs is also specified, this causes a PCM constraint to be added which enforces that only the corresponding valid sample rate can be used.

ASoC: simple-card-utils: add asoc_graph_is_ports0()

2021-10-15T15:10:36+00:00

audio-graph-card2 will support DPCM/Multi/Codec2Codec, and these will use almost same DT settings which uses ports0 and ports1. This patch adds asoc_graph_is_ports0() which checks port is under port0 or not.

ASoC: simple-card-utils: Increase maximum DAI links limit to 512

2021-09-20T12:31:28+00:00

The current limit of 128 is not sufficient when more components are added to the audio map on Tegra210 and later platforms. Thus it is resulting in probe failure. The requirement is of nearly ~200 DAI links. To give sufficient room for future additions the maximum limit is increased to 512 DAI links. This is a preparatory patch to add more components like resampler, mixer, multiplexers, demultiplexers and volume controllers to Tegra210 and later platforms.

ASoC: simple-card-utils: Increase maximum number of links to 128

2021-04-16T15:54:48+00:00

On Tegra186 and later, the number of links can go up to 72, so bump the maximum number of links to the next power of two (128).
