2017-01-11Tinyalsa: Add support to poll on alsa controlPankaj Bharadiya
ALSA controls support polling on the kcontrols, this is used in HD-A for jack notifcation. In tinyalsa we can use this for notfication from sound card for any events detected by DSP Change-Id: I4193809bfcdb60f4dc11e1c2ad6a07b29cfa80e9 Signed-off-by: Hardik T Shah <hardik.t.shah@intel.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Pankaj Bharadiya <pankaj.laxminarayan.bharadiya@intel.com>
2017-01-10Fix the byte control set/get methodPankaj Bharadiya
The TLV byte controls expect a TLV header as well. Check for TLV access and add TLV header size before invoking mixer API.

2017-01-10mixer: Add support for TLV RW access check apiPankaj Bharadiya
Tinyalsa doesn't expose an api to check TLV RW access Add mixer_ctl_is_access_tlv_rw(). This api will get used by tinymix and audio HALs for checking TLV RW access before managing the byte related mixer controls.

2016-12-02mixer: add ability to update control list with new controlsRichard Fitzgerald
New controls could appear during runtime, for example if a new firmware is downloaded to a DSP. Since ALSA drivers are not supposed to delete or renumber existing controls we can assume that any new controls will be after any controls we already know about. We can use this to enable extending our current list of controls, which is more efficient than closing the mixer session and recreating it.

2016-12-01Added function, mixer_get_num_ctls_by_nameTaylor Holberton
This function is used to get the number of mixer controls by a given name. It was added for use with mixer_get_ctl_by_name_and_index so that client code can expect the last valid index to pass.
2016-12-01Added mixer_get_ctl_constTaylor Holberton
This function was added to make available a mixer control accessor in a function that does not modify its value.
2016-12-01Added const specifier for several mixer functionsTaylor Holberton
Functions changed are: - mixer_get_name - mixer_get_num_ctls - mixer_ctl_get_id - mixer_ctl_get_name - mixer_ctl_get_type - mixer_ctl_get_type_string - mixer_ctl_get_num_values - mixer_ctl_get_num_enums - mixer_ctl_get_enum_string - mixer_ctl_get_percent - mixer_ctl_get_value - mixer_ctl_get_array - mixer_ctl_get_range_min - mixer_ctl_get_range_max
2016-11-23added mixer ctl member documentationTaylor Holberton

2016-11-19added some documentationTaylor Holberton
2016-11-19renamed doxygen group, tinyalsa-mixer to libtinyalsa-mixerTaylor Holberton
2016-10-05included only necessary headersRicardo Biehl Pasquali
If users want to use only pcm.c or mixer.c they can. It's not necessary to include tinyalsa/asoundlib.h because mixer.c doesn't use pcm.h and pcm.c doesn't use mixer.h.
