These structures are only stored in the ops field of a snd_soc_dai_driver structure. That field is declared const, so snd_soc_dai_ops structures that have this property can be declared as const also.

2017-01-17ASoC: Intel: rename SND_SST_MFLD_PLATFORM to SND_SST_ATOM_HIFI2_PLATFORMAndy Shevchenko1-0/+1
Rename SND_SST_MFLD_PLATFORM to SND_SST_ATOM_HIFI2_PLATFORM to make it clear that is not only about Medfield platform. The new name is derived from Intel Atom and HiFi2. HiFi2 is the DSP version, it's public information for Intel *Field/*Trail parts, see https://www.alsa-project.org/main/index.php/Firmware. By combining HiFi2 with Atom we get a unique non-ambiguous description of the core+DSP hardware for Intel Medfield through Intel Cherrytrail.

2016-09-12ASoC: constify snd_pcm_ops structuresJulia Lawall1-1/+1
Check for snd_pcm_ops structures that are only stored in the ops field of a snd_soc_platform_driver structure or passed as the third argument to snd_pcm_set_ops. The corresponding field or parameter is declared const, so snd_pcm_ops structures that have this property can be declared as const also. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r disable optional_qualifier@ identifier i; position p; @@ static struct snd_pcm_ops i@p = { ... }; @ok1@ identifier r.i; struct snd_soc_platform_driver e; position p; @@ e.ops = &i@p; @ok2@ identifier r.i; expression e1, e2; position p; @@ snd_pcm_set_ops(e1, e2, &i@p) @bad@ position p != {r.p,ok1.p,ok2.p}; identifier r.i; struct snd_pcm_ops e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct snd_pcm_ops i = { ... }; // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-02-02ASoC: Intel: Atom: fix regression on compress DAIPierre-Louis Bossart1-0/+1
Commit a106804 ("ASoC: compress: Fix compress device direction check") added a dependency on the compress-cpu-dai channel_min field which was removed earlier by commit 77095796 ("ASoC: Intel: Atom: clean-up compressed DAI definition") as part of the baytrail cleanups. The net result was a regression at probe on all Atom platforms with no sound card created. Fix by adding explicit initialization for channel_min to 1 for the compress-cpu-dai.

the fields channels_min, channels_max, rate and formats are irrelevant for compressed playback, they will depend on the content.

2015-11-18ASoC: Change the PCM runtime array to a listMengdong Lin1-6/+6
Currently the number of DAI links is statically defined by the machine driver at build time using an array. This makes it difficult to shrink/ grow the number of DAI links at runtime in order to reflect any changes in topology. We can change the DAI link array in the core to a list so that PCMs and FE DAI links can be added and deleted at runtime to reflect changes in use case and DSP topology. The machine driver can still register DAI links as an array. As the 1st step, this patch change the PCM runtime array to a list. A new PCM runtime is added to the list when a DAI link is bound successfully. Later patches will further implement the DAI link list. More: - define snd_soc_new/free_pcm_runtime() to create/free a runtime. - define soc_add_pcm_runtime() to add a runtime to the rtd list. - define soc_remove_pcm_runtimes() to clean up the runtime list. - traverse the rtd list to probe the link components and dais. - Add a field "num" to PCM runtime struct, used to specify the device number when creating the pcm device, and for a soc card to access its dai_props array. - The following 3rd party machine/platform drivers iterate the rtd list to check the runtimes: sound/soc/intel/atom/sst-mfld-platform-pcm.c sound/soc/intel/boards/cht_bsw_rt5645.c sound/soc/intel/boards/cht_bsw_rt5672.c sound/soc/intel/boards/cht_bsw_max98090_ti.c Signed-off-by: Mengdong Lin <mengdong.lin@linux.intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>
