ASoC: simple-card-utils: add link-trigger-order support

2024-06-26T16:47:56+00:00

Some Sound Card might need special trigger ordering which is based on CPU/Codec connection. It is already supported on ASoC, but Simple Audio Card / Audio Graph Card still not support it. Let's support it. Cc: Maxim Kochetkov Signed-off-by: Kuninori Morimoto Link: https://patch.msgid.link/87r0d2zojq.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown

ASoC: simple-card-utils: remove both playback/capture_only check

2024-06-03T14:59:33+00:00

soc-pcm.c :: soc_get_playback_capture() will indicate error if both playback_only / capture_only were true. Thus, graph_util_parse_link_direction() which setup playback_only / capture_only don't need to check it. And, its return value is not used on existing driver. Let's remove it.

ASoC: simple-card-utils: Split simple_fixup_sample_fmt func

2024-05-27T12:59:49+00:00

Split the simple_fixup_sample_fmt() into two functions by adding one more function named simple_util_get_sample_fmt() to return the sample format value. This is useful for drivers that wish to simply get the sample format without setting the mask.

ASoC: audio-graph-card2: Introduce playback-only/capture-only DAI link flags

2023-12-14T10:56:47+00:00

We need this to support MICFIL PDM found on i.MX8MP where the DAI link supports only capture direction. Signed-off-by: Daniel Baluta Link: https://msgid.link/r/20231128081119.106360-2-daniel.baluta@oss.nxp.com Signed-off-by: Mark Brown

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

2023-10-23T12:29:45+00:00

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. simple_util_remove() returned zero unconditionally. Make it return void instead and convert all users to struct platform_device::remove_new().

ASoC: remove asoc_xxx() compatible macro

No driver is using asoc_xxx() any more. This patch removes compatible macro for asoc_xxx(). Signed-off-by: Kuninori Morimoto Link: https://lore.kernel.org/r/878r8tfo06.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown

ASoC: simple_card_utils.h: convert not to use asoc_xxx()

2023-09-25T12:16:14+00:00

ASoC is using 2 type of prefix (asoc_xxx() vs snd_soc_xxx()), but these are unified into snd_soc_xxx(). simple_card / audio_graph drivers are historically using asoc_xxx() prefix too. simple_card / audio_graph are not ASoC framework, so let's use simple_card_xxx_() / audio_graph_xxx() for global function prefix. This patch has asoc_xxx() as define to keep compatible. It will be removed if all drivers were switched to new style.

ASoC: simple-card-utils.c: enable multi Component support

2023-07-17T05:15:47+00:00

If CPU/Codec driver keeps its DAI node, we can directly identify actual DAI by using snd_soc_get_dai_via_args(). This means we can use multi Component. This patch enables multi Component support on Audio Graph Card/Card2.

ASoC: simple_card_utils: remove unused cpus/codecs/platforms from props

2023-06-15T11:08:41+00:00

simple_dai_props has cpus/codecs/platforms. These pointer were used for dai_link before, but are allocated today since commit 050c7950fd70 ("ASoC: simple-card-utils: alloc dai_link information for CPU/Codec/Platform").
