| 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. |

| 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). |

| 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(). |
