| * ASoC: fill in snd_soc_pcm_runtime.card before calling snd_soc_dai_link.init()Janusz Krzysztofik2011-02-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The .card member of the snd_soc_pcm_runtime structure pointed to by the snd_soc_dai_link.init() argument used to be initialized before the function being called. This has changed, probably unintentionally, after recent refactorings. Since the function implementations are free to make use of this pointer, move its assignment back before the function is called to avoid NULL pointer dereferences.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make the format of the codec_reg file more easily parsable. Remove the header field which gives the codec name. These changes are important when it comes to extend the debugfs codec_reg file to dump more than PAGE_SIZE bytes to make it easier to calculate offsets within the file. We still need to handle the case when the snd_soc_read() call fails and <no data: %d> is outputted.

| | | | | | | | | | | | | | | | | | | | | | All ASoC cards need snd_soc_initialize_card_lists called. Previously, it was only called for cards backed by a "soc-audio" platform device, via soc_probe(). However, it's also needed for cards backed by other platform devices, and registered directly via snd_soc_register_card().

* | ASoC: Provide per widget type callback when executing DAPM sequencesMark Brown2011-01-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Many modern devices have features such as DC servos which take time to start. Currently these are handled by per-widget events but this makes it difficult to paralleise operations on multiple widgets, meaning delays can end up being needlessly serialised. By providing a callback to drivers when all widgets of a given type have been handled during a DAPM sequence the core allows drivers to start operations separately and wait for them to complete much more simply.

* ASoC: Extend DAPM to handle power changes on cross-device pathsJarkko Nikula2010-12-151-0/+2
| | | | | | | | | | | | | | | | | | | Power change event like stream start/stop or kcontrol change in a cross-device path originates from one device but codec bias and widget power changes must be populated to another devices on that path as well. This patch modifies the dapm_power_widgets so that all the widgets on a sound card are checked for a power change, not just those that are specific to originating device. Also bias management is extended to check all the devices. Only exception in bias management are widgetless codecs whose bias state is changed only if power change is originating from that context. DAPM context test is added to dapm_seq_run to take care of if power sequence extends to an another device which requires separate register writes.

* ASoC: Move widgets from DAPM context to snd_soc_cardJarkko Nikula2010-12-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Decoupling widgets from DAPM context is required when extending the ASoC core to cross-device paths. Even the list of widgets are now kept in struct snd_soc_card, the widget listing in sysfs and debugs remain sorted per device. This patch makes possible to build cross-device paths but does not extend yet the DAPM to handle codec bias and widget power changes of an another device. Cross-device paths are registered by listing the widgets from device A in a map for device B. In case of conflicting widget names between the devices, a uniform name prefix is needed to separate them. See commit ead9b91 "ASoC: Add optional name_prefix for kcontrol, widget and route names" for help. An example below shows a path that connects MONO out of A into Line In of B: static const struct snd_soc_dapm_route mapA[] = { {"MONO", NULL, "DAC"}, }; static const struct snd_soc_dapm_route mapB[] = { {"Line In", NULL, "MONO"}, }; Signed-off-by: Jarkko Nikula <jhnikula@gmail.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

* | ASoC: soc-core: Generalize snd_soc_prefix_map and rename to snd_soc_codec_confDimitris Papastamos2010-12-031-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The snd_soc_codec_conf struct now holds codec specific configuration information. A new configuration option has been added to allow machine drivers to override the compression type set by the codec driver. In the absence of providing an snd_soc_codec_conf struct or when providing one but not setting the compress_type member to anything, the one supplied by the codec driver will be used instead. In all other cases the one set in the snd_soc_codec_conf struct takes effect.
