1 | config SOUND |
| 2 | bool "Enable sound support" | |
| 3 | help | |
| 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. | |
| 8 | ||
| 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. | |

| 14 | bool "Enable I2S support" | |
| 15 | depends on SOUND | |
| 16 | help | |
| 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). | |

| 23 | bool "Enable I2C support for Samsung SoCs" | |
| 24 | depends on SOUND | |
| 25 | help | |
| 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(). | |

| 33 | bool "Support Maxim max98095 audio codec" | |
| 34 | depends on I2S_SAMSUNG | |
| 35 | help | |
| 36 | Enable the max98095 audio codec. This is connected via I2S for | |
| 37 | audio data and I2C for codec control. At present it only works | |
| 38 | with the Samsung I2S driver. | |

| 41 | bool "Support sandbox emulated audio codec" | |
| 42 | depends on SANDBOX && SOUND | |
| 43 | help | |
| 44 | U-Boot sandbox can emulate a sound device using SDL, playing the | |
| 45 | sound on the host machine. This option implements the sound_init() | |
| 46 | and sound_play() functions for sandbox. Note that you must install | |
| 47 | the SDL libraries for this to work. | |

| 52 | help | |
| 53 | Enable the wm8994 audio codec. This is connected via I2S for | |
| 54 | audio data and I2C for codec control. At present it only works | |
| 55 | with the Samsung I2S driver. |
