   4           Support making sounds through an audio codec. This is normally a
   5           beep at a chosen frequency for a selected length of time. However
   6           the drivers support playing arbitrary sound samples using a
   7           PCM interface.

   9           Note: At present the sound setup is somewhat tangled up in that the
  10           audio codecs are called from the sound-i2s code. This could be
  11           converted to driver model.

  17           I2S is a serial bus often used to transmit audio data from the
  18           SoC to the audio codec. This option enables sound support using
  19           I2S. It calls either of the two supported codecs (no use is made
  20           of driver model at present).

  26           Samsung Exynos SoCs support an I2S interface for sending audio
  27           data to an audio codec. This option enables support for this,
  28           using one of the available audio codec drivers. Enabling this
  29           option provides an implementation for sound_init() and
  30           sound_play().
