* ASoC: add snd_soc_get_dai_id() functionKuninori Morimoto2017-05-241-0/+3
| | | | | | | | | | | | | | | | | | | | ALSA SoC needs to know connected DAI ID for detecting. It is not a big problem if device/driver was only for sound, but getting DAI ID will be difficult if device includes both Video/Sound, like HDMI. To solve this issue, this patch adds new snd_soc_get_dai_id() and its related .of_xlate_dai_id callback on component driver. In below case, we can handle Sound port (= port@2) as ID = 0 if .of_xlate_dai_id has its support. hdmi { port@0 { /* VIDEO */ }; port@1 { /* VIDEO */ }; port@2 { /* SOUND */ }; }; Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>

| | * ASoC: jack: add snd_soc_codec_set_jackBard Liao2017-04-101-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are many codecs with the capability of jack detection. Usually, we create a jack on machine driver but there is no common function for machine driver to deliver the jack pointer to codec driver. snd_soc_codec_set_jack can be used for delivering the jack pointer to codec driver and enable the jack detection function. To make it work, codec driver need to define a callback function to receive the jack pointer and do all necessary procedure for enabling jack detection.

* / / ASoC: core: remove pointless auxiliary from snd_soc_componentKuninori Morimoto2017-03-241-1/+0
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 1a653aa44725 ("ASoC: core: replace aux_comp_list to ...") tried to replace aux_comp_list to component_dev_list, but it failed because of binding timing. Thus, Sylwester fixuped it by commit d2e3a1358c37 ("ASoC: Fix binding and probing of auxiliary..."). One of main purpose of commit 1a653aa44725 ("ASoC: core: replace...") was remove replaceable list (= list_aux) from snd_soc_component by using new "auxiliary" flags (but it failed). Because of this background, current code has reborned card_aux_list (= same as original list_aux), and almost pointless "auxiliary" flags. Let's remove pointless "auxiliary" flags by this patch This means, it is same as revert both commit 1a653aa44725 ("ASoC: core: replace aux_comp_list to ...") and commit d2e3a1358c37 ("ASoC: Fix binding and probing of auxiliary...").

| * | ASoC: core: Add API to use DMI name in sound card long nameLiam Girdwood2017-01-171-0/+4
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Intel DSP platform drivers are used by many different devices but are difficult for userspace to differentiate. This patch adds an API to allow the DMI name to be used in the sound card long name, thereby helping userspace load the correct UCM configuration. Usually machine drivers uses their own name as the sound card name (short name), and leave the long name and driver name blank. This API will use the DMI info like vendor, product and board to make up the card long name. If the machine driver has already explicitly set the long name, this API will do nothing. This patch also allows for further differentiation as many devices that share the same DMI name i.e. Minnowboards, UP boards may be configured with different codecs or firmwares. The API supports flavoring the DMI name into the card longname to provide the extra differentiation required for these devices. For Use Case Manager (UCM) in the user space, changing card long name by this API is backward compatible, since the card name does not change. For a given sound card, even if there is no device-specific UCM configuration file that uses the card long name, UCM will fall back to load the default configuration file that uses the card 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.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's often the case that a codec driver will need to control its own pins. However, if a name_prefix has been applied to this codec it must be included in the name passed to any of the snd_soc_dapm_x_pin() functions. The behaviour of the existing pin control functions is reasonable, since you may want to search for a fully-specified name within the scope of an entire card. This means that we can't apply the prefix in these functions because it will break card-scope searches. Constructing a prefixed string "manually" in codec drivers leads to a lot of repetition of the same code. To make this tidier in codec drivers this patch adds a new set of equivalent functions that take a struct snd_soc_component instead of a dapm context and automatically add the component's name_prefix to the given name. This makes it a simple change in codec drivers to be prefix-safe. The new functions are not quite trivial enough to be inlines and the compiler won't be able to compile-away any part of them. Although it looks somewhat inefficient to have to allocate a temporary buffer and combine strings, the current design of the widget list doesn't lend itself to a more optimized implementation - it's a single list of all widgets on a card and is searched linearly for a matching string. As pin state changes are generally low-frequency events it's unlikely to be a significant issue - at least not enough to rewrite the widget list handling just for this.

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.

| * ASoC: Support registering a DAI dynamicallyMengdong Lin2016-01-101-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
