The U-Boot sound system provides basic support for beeping. At present it does not use driver model, but it needs to be converted. Add an option to enable driver model for sound. For now it is not connected to anything. Future work will add drivers which use this option. It will then be removed once everything is converted. Signed-off-by: Simon Glass <sjg@chromium.org>

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).

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().

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.

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.
