   4         bool "Enable sound support"
   5         help
   6           Support making sounds through an audio codec. This is normally a
   7           beep at a chosen frequency for a selected length of time. However
   8           the drivers support playing arbitrary sound samples using a
   9           PCM interface.
  10
  11           Note: At present the sound setup is somewhat tangled up in that the
  12           audio codecs are called from the sound-i2s code. This could be
  13           converted to driver model.

  15 config I2S
  16         bool "Enable I2S support"
  17         depends on SOUND
  18         help
  19           I2S is a serial bus often used to transmit audio data from the
  20           SoC to the audio codec. This option enables sound support using
  21           I2S. It calls either of the two supported codecs (no use is made
  22           of driver model at present).
  23
  24 config I2S_SAMSUNG
  25         bool "Enable I2C support for Samsung SoCs"
  26         depends on SOUND
  27         help
  28           Samsung Exynos SoCs support an I2S interface for sending audio
  29           data to an audio codec. This option enables support for this,
  30           using one of the available audio codec drivers. Enabling this
  31           option provides an implementation for sound_init() and
  32           sound_play().
  33
  34 config SOUND_MAX98095
  35         bool "Support Maxim max98095 audio codec"
  36         depends on I2S_SAMSUNG
  37         help
  38           Enable the max98095 audio codec. This is connected via I2S for
  39           audio data and I2C for codec control. At present it only works
  40           with the Samsung I2S driver.
  41
  42 config SOUND_SANDBOX
  43         bool "Support sandbox emulated audio codec"
  44         depends on SANDBOX && SOUND
  45         help
  46           U-Boot sandbox can emulate a sound device using SDL, playing the
  47           sound on the host machine. This option implements the sound_init()
  48           and sound_play() functions for sandbox. Note that you must install
  49           the SDL libraries for this to work.

  51 config SOUND_WM8994
  52         bool "Support Wolfson Micro wm8994 audio codec"
  53         depends on I2S_SAMSUNG
  54         help
  55           Enable the wm8994 audio codec. This is connected via I2S for
  56           audio data and I2C for codec control. At present it only works
  57           with the Samsung I2S driver.
