      ASoC: Add power supply widget to DAPM · 246d0a17
      Mark Brown 提交于
      Many modern CODECs have shared resources on chip which must be enabled
      for portions of the chip to work but which can be disabled at other times
      in order to achieve power savings. Examples of such resources include
      power supplies and some internal clocks.
      
      Since these widgets are dependencies for the audio path but do not carry
      audio signals they require slightly different handling to most widgets -
      they do not contribute to the audio path and so should not be counted as
      either inputs or outputs during path walks.
      
      Cases where one supply provides a supply for another will require
      additional work. There is also room for more optimisation of the graph
      walking to avoid repeated checks for the same thing.

      ASoC: Provide core support for symmetric sample rates · 06f409d7
      Mark Brown 提交于
      Many devices require symmetric configurations of capture and playback
      data formats, often due to shared clocking but sometimes also due to
      other shared playback and record configuration in the device. Start
      providing core support for this by allowing the DAIs or the machine
      to specify that the sample rates used should be kept symmetric.
      
      A flag symmetric_rates is provided in the snd_soc_dai and
      snd_soc_dai_link structures. If this is set in either of the DAIs or in
      the machine then a constraint will be applied when a stream is already
      open preventing any changes in sample rate.

      ASoC: Add GPIO support for jack reporting interface · ec67624d
      Lopez Cruz, Misael 提交于
      Add GPIO support to jack reporting framework in ASoC using gpiolib calls.
      The gpio support exports two new functions: snd_soc_jack_add_gpios and
      snd_soc_jack_free_gpios.
      
      Client drivers using gpio feature must pass an array of jack_gpio pins
      belonging to a specific jack to the snd_soc_jack_add_gpios function. The
      framework will request the gpios, set the data direction and request irq.
      The framework will update power status of related jack_pins when an event on
      the gpio pins comes according to the reporting bits defined for each gpio.
      
      All gpio resources allocated when adding jack_gpio pins can be released
      using snd_soc_jack_free_gpios function.

      ALSA: Introduce snd_card_create() · 53fb1e63
      Takashi Iwai 提交于
      Introduced snd_card_create() function as a replacement of snd_card_new().
      The new function returns a negative error code so that the probe callback
      can return the proper error code, while snd_card_new() can give only NULL
      check.
      
      The old snd_card_new() is still provided as an inline function but with
      __deprecated attribute.  It'll be removed soon later.
