4 bool "Enable sound support"
6 Support making sounds through an audio codec. This is normally a
7 beep at a chosen frequency for a selected length of time. However
8 the drivers support playing arbitrary sound samples using a
11 Note: At present the sound setup is somewhat tangled up in that the
12 audio codecs are called from the sound-i2s code. This could be
13 converted to driver model.
16 bool "Use driver model for sound"
18 Enable this option to use driver model for sound devices. This is a
19 migration option and will be removed.
22 bool "Enable I2S support"
25 I2S is a serial bus often used to transmit audio data from the
26 SoC to the audio codec. This option enables sound support using
27 I2S. It calls either of the two supported codecs (no use is made
28 of driver model at present).
31 bool "Enable I2C support for Samsung SoCs"
34 Samsung Exynos SoCs support an I2S interface for sending audio
35 data to an audio codec. This option enables support for this,
36 using one of the available audio codec drivers. Enabling this
37 option provides an implementation for sound_init() and
41 bool "Support Maxim max98095 audio codec"
42 depends on I2S_SAMSUNG
44 Enable the max98095 audio codec. This is connected via I2S for
45 audio data and I2C for codec control. At present it only works
46 with the Samsung I2S driver.
49 bool "Support sandbox emulated audio codec"
50 depends on SANDBOX && SOUND
52 U-Boot sandbox can emulate a sound device using SDL, playing the
53 sound on the host machine. This option implements the sound_init()
54 and sound_play() functions for sandbox. Note that you must install
55 the SDL libraries for this to work.
58 bool "Support Wolfson Micro wm8994 audio codec"
59 depends on I2S_SAMSUNG
61 Enable the wm8994 audio codec. This is connected via I2S for
62 audio data and I2C for codec control. At present it only works
63 with the Samsung I2S driver.
