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.

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).

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().

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.
