ASoC: simple-card-utils: remove asoc_simple_convert_fixup()

2022-11-07T13:58:05Z

No one is using asoc_simple_convert_fixup(), we don't need to export its symbol. This patch removes it. Signed-off-by: Kuninori Morimoto Link: https://lore.kernel.org/r/874jvj8ftp.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown

ASoC: simple-card: Fix up checks for HW param fixups

2022-10-19T12:39:34Z

The "convert-xxx" properties only have an effect for DPCM DAI links. A DAI link is only created as DPCM if the device tree requires it; part of this involves checking for the use of "convert-xxx" properties. When the convert-sample-format property was added, the checks got out of sync. A DAI link that specified only convert-sample-format but did not pass any of the other DPCM checks would not go into DPCM mode and the convert-sample-format property would be silently ignored. Fix this by adding a function to do the "convert-xxx" property checks, instead of open-coding it in simple-card and audio-graph-card. And add "convert-sample-format" to the check function so that DAI links using it will be initialized correctly.

ASoC: simple-card-utils: switch to using gpiod API

2022-09-07T11:42:22Z

This patch switches the driver away from legacy gpio/of_gpio API to gpiod API, and removes use of of_get_named_gpio_flags() which I want to make private to gpiolib.

ASoC: simple-card-utils: Fixup DAI sample format

2022-08-15T00:19:55Z

Parse "convert-sample-format" DT binding and fixup the sample format as applicable. This is similar to the existing "convert-channels" and "convert-rate" properties for channels and rate fixup respectively.

ASoC: simple-card-utils.c: care Codec2Codec vs DPCM:BE

2022-07-08T10:51:46Z

Current asoc_simple_init_for_codec2codec() adds default Codec2Codec settings if rtd was Codec only. But DPCM:BE also judged as Codec only, because dummy-DAI doesn't have "endianness" (which is key parameter to judge as Codec). This patch ignores setup Codec2Codec settings if it was DPCM:BE case.

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

2022-07-08T10:51:43Z

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.

Specify clock provider directly to CPU DAIs

2022-06-09T10:56:32Z

Merge series from Charles Keepax : Currently the set_fmt callback always passes clock provider/consumer with respect to the CODEC. This made sense when the framework was directly broken down into platforms and CODECs. However, as things are now broken down into components which can be connected as either the CPU or CODEC side of a DAI link it simplifies things if each side of the link is just told if it is provider or consumer of the clocks. Making this change allows us to remove one of the last parts of the ASoC core that needs to know if a driver is a CODEC driver, where it flips the clock format specifier if a CODEC driver is used on the CPU side of a DAI link, as well as just being conceptually more consistent with componentisation. The basic idea of this patch chain is to change the set_fmt callback from specifying if the CODEC is provider/consumer into directly specifying if the component is provider/consumer. To do this we add some new defines, and then to preserve bisectability, the migration is done by adding a new callback, converting over all existing CPU side drivers, converting the core, and then finally reverting back to the old callback. Converting the platform drivers makes sense as the existing defines are from the perspective of the CODEC and there are more CODEC drivers than platform drivers. Obviously a fair amount of this patch chain I was only able to build test, so any testing that can be done would be greatly appreciated.

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

2022-06-07T11:00:43Z

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: simple-card-utils: rename asoc_simple_init_dai_link_params() to asoc_simple_init_for_codec2codec()

2022-06-06T11:38:40Z

commit 95cfc0a0aaf5752071 ("ASoC: simple-card: Add support for codec2codec DAI links") added the function asoc_simple_init_dai_link_params() to initialize dai_link "params". It is very straight naming, but difficult to noticed that it is for Codec2Codec support. Handling Codec2Codec is one of very tricky part on ALSA SoC, thus it is very important to clarify it. This patch renames the function name. Signed-off-by: Kuninori Morimoto Link: https://lore.kernel.org/r/87o7zflk3n.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown
