| config SOUND |
| bool "Enable sound support" |
| help |
| Support making sounds through an audio codec. This is normally a |
| beep at a chosen frequency for a selected length of time. However |
| the drivers support playing arbitrary sound samples using a |
| PCM interface. |
| |
| Note: At present the sound setup is somewhat tangled up in that the |
| audio codecs are called from the sound-i2s code. This could be |
| converted to driver model. |
| |
| config DM_SOUND |
| bool "Use driver model for sound" |
| help |
| Enable this option to use driver model for sound devices. This is a |
| migration option and will be removed. |
| |
| config I2S |
| bool "Enable I2S support" |
| depends on SOUND |
| help |
| I2S is a serial bus often used to transmit audio data from the |
| SoC to the audio codec. This option enables sound support using |
| I2S. It calls either of the two supported codecs (no use is made |
| of driver model at present). |
| |
| config I2S_SAMSUNG |
| bool "Enable I2C support for Samsung SoCs" |
| depends on SOUND |
| help |
| Samsung Exynos SoCs support an I2S interface for sending audio |
| data to an audio codec. This option enables support for this, |
| using one of the available audio codec drivers. Enabling this |
| option provides an implementation for sound_init() and |
| sound_play(). |
| |
| config SOUND_MAX98095 |
| bool "Support Maxim max98095 audio codec" |
| depends on I2S_SAMSUNG |
| help |
| Enable the max98095 audio codec. This is connected via I2S for |
| audio data and I2C for codec control. At present it only works |
| with the Samsung I2S driver. |
| |
| config SOUND_SANDBOX |
| bool "Support sandbox emulated audio codec" |
| depends on SANDBOX && SOUND |
| help |
| U-Boot sandbox can emulate a sound device using SDL, playing the |
| sound on the host machine. This option implements the sound_init() |
| and sound_play() functions for sandbox. Note that you must install |
| the SDL libraries for this to work. |
| |
| config SOUND_WM8994 |
| bool "Support Wolfson Micro wm8994 audio codec" |
| depends on I2S_SAMSUNG |
| help |
| Enable the wm8994 audio codec. This is connected via I2S for |
| audio data and I2C for codec control. At present it only works |
| with the Samsung I2S driver. |
