From 94f99c875c109e51decf0d8c25ec2c946db20c56 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Mon, 16 Jun 2014 18:13:01 +0200 Subject: ASoC: Move name_prefix from CODEC to component Move the name_prefix from the CODEC struct to the component struct. This will eventually allow to specify prefixes for all types of components. It is also necessary to make the DAPM code component type independent (i.e. a DAPM context does not need to know whether it belongs to a CODEC or a platform or something else).

Using a 2-stage registration approach has the advantage that it is possible to modify the component after it has been initialized, but before it is made visible to the system. This e.g. allows CODECs or platforms to overwrite some of the default settings made in snd_soc_component_initialize(). Similar snd_soc_component_unregister() is split into two steps as well, snd_soc_component_delete(), which removes the component from the system, and snd_soc_component_cleanup(), which frees all the resources allocated by the component. Furthermore this patch makes sure that if a component is visible on two list (e.g. the component list and the CODEC list) it is added or removed to both lists atomically.

This makes sense since widgets which qualify for auto-disconnection are only found in CODEC DAPM contexts. But with componentisation this is going to change, so consider all widgets for auto-disconnection. Also it is probably faster to walk the widgets list only once rather than once for each CODEC.

This patch adds a new set_bias_level() callback to the DAPM context struct. The DAPM code will use this new callback instead of the CODEC callback. For CODECs the new callback is set up to call the CODEC specific set_bias_level callback(). Not looking directly at the CODEC driver struct will allow non CODEC DAPM contexts to implement a set_bias_level() callback. This is also similar to how the seq_notifier() and stream_event() callbacks are currently handled.

Previously there was only full DAPM support for CODECs and partial DAPM support (e.g. no Mixers nor MUXs) for platforms. Having DAPM support at the component level will allow all types of components to use DAPM and also help in consolidating the DAPM support between CODECs and platforms. Since the DAPM context is directly embedded into the snd_soc_codec and snd_soc_platform struct and the 'dapm' field is directly referenced in a lot of drivers moving the field just right now is not possible without causing code churn. The approach this patch takes is to add two new fields to the component struct. One field which is the pointer to the actual DAPM context used by the component and one DAPM context that will be used as the default if no other context was specified. For CODECs and platforms the pointer is initialized to point to the CODEC or platform DAPM context. All generic code when referencing a component's DAPM struct will go via the pointer. This will make it possible to eventually seamlessly move the DAPM context from snd_soc_codec and snd_soc_platform struct over once all direct references have been eliminated.

This is meant to unify the handling of these callbacks across different types of components and will eventually allow their removal from the CODEC and platfrom driver structs. The new callbacks are slightly different from the old ones in that they take a snd_soc_component as a parameter rather than a snd_soc_dapm_context. This was done since otherwise casting from the DAPM context to the component would typically be the first thing to do in the callback. And the interface becomes slightly cleaner by passing a snd_soc_component to all callbacks in the snd_soc_component_driver struct. The patch also already removes the stream_event() callback from the snd_soc_codec_driver and snd_soc_platform_driver structs as it is currently unused.

This means that we need to lookup the aux dev again in soc_probe_aux_dev(). This patch changes the behavior to assign the aux dev to the rtd in soc_check_aux_dev() (and renames it to soc_bind_aux_dev()). This simplifies the implementation a bit and also removes the need for soc_post_component_init() to know about the specific CODEC that was assigned to the rtd. The later is necessary for componentization as the code should work for all types of components not just CODECs. This new behavior is also more in sync with how soc_bind_dai_link()/soc_probe_link_dais() works.

In some cases, the same CPU DAI can be connected to several codecs. This is the case for example, if you connect two mono codecs to the same I2S link in order to have a stereo card. The current ASoC implementation does not allow such setup. Add support for DAI links composed of a single CPU DAI and multiple CODECs. Sound cards have to pass the CODECs array in the corresponding DAI link through a new 'snd_soc_dai_link_component' struct. Each CODEC in this array is described in the same manner single CODEC DAIs are (either DT/OF node or codec_name). Multi-codec links are not supported in the case of CODEC to CODEC links. Just print a warning if it happens. Based on an original code done by Misael.

This patch moves the card field to the component level which will allow further code consolidation between platforms and CODECS. Since there are only a handful of users of the snd_soc_codec struct's card field (and none of the snd_soc_platform's) these are update in this patch as well, which allows it to be removed from the snd_soc_codec struct.
