• d7821953c   ASoC: wm8962: Let CODEC driver enable and disable its own MCLK ... Browse Code »

  snd_soc_open() will trigger pm_runtime resume() which will then enable
  the regulator and initialization. So we should make sure the MCLK is
  enabled before this resume().

  Previously we let the machine driver get the clock and enable it in
  its probe(). However, considering about power saving, it'll be better
  to enable it when it's going to be used and disable it after using.

  So this patch just simply adds clk_get() and clk_enable() to WM8962
  driver. Meanwhile, it marks clock pointer to NULL if no clock assigned
  to it so it will not break any current function.

  When the hardware is configured with one or both of the IN4 inputs used
  for DC measurement (with no DC blocking capacitor connected) then we can
  improve power consumption slightly in idle modes by applying a register
  write sequence. Provide platform data to enable this, implemented using
  a regmap patch.

  Add the widget for MICBIAS power control and allow configuration of the
  microphone bias setup via the platform data for the WM8962. When
  microphone status signals are brought out to GPIO this should be
  sufficient to enable microphone detection.

  Provide an initial hookup for interrupts on the WM8962. Currently we simply
  report error status via log messages if an IRQ is provided for the device.

  The WM8962 is a low power, high performance stereo CODEC designed for
  portable digital audio applications.

  This initial driver release supports the key audio paths of the WM8962.
  Extended functionality, such as microphone detection, digital microphones
  and the advanced DSP signal enhancements provided by the device are not
  yet supported.
