| | * | | | | ASoC: Define add/remove_dai_link ops for a soc cardMengdong Lin2015-12-081-0/+5

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.

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. And they will also be added to the list. Signed-off-by: Mengdong Lin <mengdong.lin@linux.intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>

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>

DSPs can have modules which take audio data, process it and are capable of generating events thus acting as a sink of data. To make the dapm graph complete for such paths we need a dapm sink widget for these modules, so add a SND_SOC_DAPM_SINK to declare such a widget.

Ideally all these should be factored out into hdac_i915.c. This patch does it, adds two new helper functions for setting N/CTS and fetching ELD bytes. One bonus is that the hackish widget vs port mapping is also moved to hdac_i915.c, so that it can be fixed / enhanced more cleanly.

| | * | | ASoC: Add info callback for SX_TLV controlsCharles Keepax2015-10-161-2/+4

Currently every CODEC implementing these controls specifies the minimum as the non-zero value for the minimum and the maximum as the number of gain settings available. This means when the info callback subtracts the minimum value from the maximum value to calculate the number of gain levels available it is actually under reporting the available levels. This patch fixes this issue by adding a new snd_soc_info_volsw_sx callback that does not subtract the minimum value.
