      ASoC: Add indirection for CODEC private data · b2c812e2
      Mark Brown 提交于
      One of the features of the multi CODEC work is that it embeds a struct
      device in the CODEC to provide diagnostics via a sysfs class rather than
      via the device tree, at which point it's much better to use the struct
      device private data rather than having two places to store it. Provide
      an accessor function to allow this change to be made more easily, and
      update all the CODEC drivers are updated.
      
      To ensure use of the accessor the private data structure member is
      renamed, meaning that if code developed with older an older core that
      still uses private_data is merged it will fail to build.

      ASoC: Codec driver for Texas Instruments tlv320dac33 codec · c8bf93f0
      Peter Ujfalusi 提交于
      Driver for Texas Instruments TLV320DAC33 (SLAS546) low power stereo
      audio DAC.
      
      TLV320DAC33 is a stereo audio codec with integrated 24KB FIFO for low
      power audio playback.
      
      The digital interface can use I2S, DSP (A or B), Right and Left
      justified formats.
      DAC33 has stereo analog input, which can be bypassed to the analog
      outputs.
      
      Regarding to the internal 24KB FIFO the driver implements 'FIFO bypass'
      mode (default) and nSample mode (FIFO is in use).
      a) In 'FIFO bypass' mode the internal FIFO is not in use, the codec is
      working synchronously as a normal codec (it needs constant stream of
      data on the digital interface).
      
      b) The nSample mode implementation uses one interrupt line from DAC33 to
      the host:
      Alarm threshold is set to 10ms of audio data (limit by the driver
      implementation).
      DAC33 will signal an interrupt, when the FIFO level goes under the
      Alarm threshold.
      The host will write to nSample register a value (number of stereo
      samples), to tell DAC33 how many samples it should read in a burst from
      the host. When the DAC33 received the number of samples, it disables the
      clocks on the I2S bus. When the FIFO use again goes under the Alarm
      threshold, DAC33 signals the host with an interrupt, and the process is
      repeated.
