Components can define multiple DAIs and hence using just a device name won't help either. Thus DT device node reference and DAI names are used to uniquely represent DAI link names.

Such DAI links have CPU component which implement either pcm_construct() or pcm_new() at component or dai level respectively. Based on this, current patch exposes a helper function to identify such components and populate 'no_pcm' flag for DPCM DAI link. This helps to have BE<->BE component links where PCM devices need not be created for CPU component involved in such links.

Idea is to leverage simple or graph card driver as much as possible and vendor can maintain a thin driver to control the behavior by populating these newly exposed members. Following are the members added in 'asoc_simple_priv': - 'ops' struct: In some cases SoC vendor drivers may want to implement 'snd_soc_ops' callbacks differently. In such cases custom callbacks would be used. - 'force_dpcm' flag: Right now simple or graph card drivers detect DAI links as DPCM links if: * The dpcm_selectable is set AND * Codec is connected to multiple CPU endpoints or aconvert property is used for rate/channels. So there is no way to directly specify usage of DPCM alone. So a flag is exposed to mark all links as DPCM. Vendor driver can set this if required. - 'dpcm_selectable': Currently simple or audio graph drivers provide a way to enable this for specific compatibles. However vendor driver may want to define some additional info. Thus expose this variable where vendor drivers can set this if required. - 'data': A void pointer member is provided. This would be useful when vendor driver wants to define its own structure for internal usage and still wants to rely on most of the other members from 'asoc_simple_priv'. Subsequent patches in the series illustrate usage for above.

Functionally there is no change in behavior if these are not populated. So following changes are made as part of this. - Update 'dai_link->ops' for DPCM links if a custom 'snd_soc_ops' is defined by the vendor driver. - Consider 'force_dpcm' flag status when deciding if a DAI link needs to be treated as DPCM or not. In doing so the logic is moved to a separate inline function for a better readability. - Populate 'dpcm_selectable' flag which is then used to detect DPCM DAI links.

Idea is vendors can have a thin driver and re-use common stuff from audio graph driver. - graph_card_probe() - graph_get_dais_count() - graph_parse_of() In doing so a new header file is added for audio graph which can be included by vendor drivers.

It re-uses most of the common stuff from audio graph driver and uses the same DT binding. Required Tegra specific customizations are done in the driver. Details on the customizations done: - Update PLL rates at runtime: Tegra HW supports multiple sample rates (multiples of 8x and 11.025x) and both of these groups require different PLL rates. Hence there is a requirement to update this at runtime. This is achieved by providing a custom 'snd_soc_ops' and in hw_param() callback PLL rate is updated as per the sample rate. - Internal structure 'tegra_audio_graph_data' is used to maintain clock handles of PLL. - The 'force_dpcm' flag is set to use DPCM for all DAI links. - The 'component_chaining' flag is set to use DPCM with component model.
