snd_soc_get_dai_name() is used from snd_soc_of_get_dai_name(), and it is assuming that DT is using "sound-dai" / "#sound-dai-cells". But graph base DT is using "remote-endpoint".

2016-11-09ASoC: core: If a platform doesn't have an of_node use parent's nodeCharles Keepax
Support was added to allow location of both CPU and CODEC components of a DAI link from their parent's of_node if they did not have an of_node themselves in this commit: commit 3e0aa8d83bf8 ("ASoC: core: If component doesn't have of_node use parent's node instead") However this leaves platforms as something of a special case as the major DAI component that doesn't do this. Since this is useful for MFD devices which often utilise a single device tree entry for the whole device, add support for looking up platforms from the parent's of_node as well.

2016-11-04ASoC: Define API to find a dai linkMengdong Lin
Define the API to find an existing DAI link of the soc card by matching the ID, name and stream name. Some cards may use unique ID for each DAI link, so matching ID is enough, and name or stream name are not necessary. But user need to specify name or stream name as well if not sure whether link ID is unique since most cards use 0 as the default link ID. Topology can use this API to find an existing BE link and configure it. Signed-off-by: Mengdong Lin <mengdong.lin@linux.intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2016-08-19ASoC: core: Clean up DAPM before the card debugfsMark Brown
Both the card and DAPM cleanups recursively delete their debugfs directories. Since the DAPM debugfs subdirectory for the card is located within the card debugfs this means we end up trying to double free the DAPM subdirectory. Reorder the cleanup to free the card debugfs after we've cleaned up DAPM and it has deleted its own subdirectory.

2016-08-11ASoC: Fix leak of rtd in soc_bind_dai_linkCharles Keepax
If we fail to find a platform we simply return EPROBE_DEFER, but we have allocated the rtd pointer. All error paths before soc_add_pcm_runtime need to call soc_free_pcm_runtime first to avoid leaking the rtd pointer. A suitable error path already exists and is used else where in the function so simply use that here as well.

2016-01-10ASoC: Make aux_dev more like a generic componentMengdong Lin
aux_dev is mainly used by the machine driver to specify analog devices, which are registered as codecs. Making it more like a generic component can help the machine driver to use it to specify any component with topology info by name. Details: - Remove the stub 'rtd_aux' array from the soc card. - Add a list 'aux_comp_list' to store the components of aux_devs. And add a list head 'list_aux' to struct snd_soc_component, for adding such components to the above list. - Add a 'init' ops to a component for machine specific init. soc_bind_aux_dev() will set it to be aux_dev's init. And it will be called when probing the component. - soc_bind_aux_dev() will also search components by name of an aux_dev, since it may not be a codec. - Move probing of aux_devs before checking new DAI links brought by topology. - Move removal of aux_devs later than removal of links. Because topology of aux components may register DAIs and the DAI drivers will go with removal of the aux components, we want soc_remove_link_dais() to remove the DAIs at first.

2016-01-10ASoC: Support registering a DAI dynamicallyMengdong Lin
Define API snd_soc_register_dai() to add a DAI dynamically and create the DAI widgets. Topology can use this API to register DAIs when probing a component with topology info. These DAIs's playback & capture widgets will be freed when the sound card is unregistered and the DAIs will be freed when cleaning up the component. And a dobj is embedded into the struct snd_soc_dai_driver. Topology can use the dobj to find the DAI drivers created by it and free them when the topology component is removed.

2015-12-08ASoC: Define add/remove_dai_link ops for a soc cardMengdong Lin
A machine driver can register the two ops. When a DAI link is added or removed by a component's topology, the ASoC core can call the ops to notify the machine driver for extra intialization or destruction. E.g. topology can create FE DAI links from a cpu DAI component, and the machine driver may define an add_dai_link ops to set machine-specific .init ops for the DAI link.

Implement a dai link list for the soc card. Add APIs to add/remove a DAI links dynamically, e.g. by topology. And a dobj is embedded into the struct snd_soc_dai_link. Topology can use the dobj to find the links created by it and remove them when the topology component is unloaded. The predefined DAI links are reserved to keep backward compatibility.

2015-11-18ASoC: Change the PCM runtime array to a listMengdong Lin
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>

This fixes a sparse warning couple of lines later when be32_to_cpup() is used to convert from big endian to cpu endian.
