3config SOUND
4	bool "Enable sound support"
5	help
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
9	  PCM interface.
10
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.
14
15config I2S
16	bool "Enable I2S support"
17	depends on SOUND
18	help
19	  I2S is a serial bus often used to transmit audio data from the
20	  SoC to the audio codec. This option enables sound support using
21	  I2S. It calls either of the two supported codecs (no use is made
22	  of driver model at present).
23
24config I2S_ROCKCHIP
25	bool "Enable I2S support for Rockchip SoCs"
26	depends on I2S
27	help
28	  Rockchip SoCs support an I2S interface for sending audio data to an
29	  audio codec. This option enables support for this, using one of the
30	  available audio codec drivers. This driver does not make use of
31	  DMA, but writes each word directly to the hardware.
32
33config I2S_SAMSUNG
34	bool "Enable I2C support for Samsung SoCs"
35	depends on SOUND
36	help
37	  Samsung Exynos SoCs support an I2S interface for sending audio
38	  data to an audio codec. This option enables support for this,
39	  using one of the available audio codec drivers. Enabling this
40	  option provides an implementation for sound_init() and
41	  sound_play().
42
43config SOUND_MAX98090
44	bool "Support Maxim max98090 audio codec"
45	depends on I2S_SAMSUNG
46	help
47	  Enable the max98090 audio codec. This is connected via I2S for
48	  audio data and I2C for codec control. At present it only works
49	  with the Samsung I2S driver.
50
51config SOUND_MAX98095
52	bool "Support Maxim max98095 audio codec"
53	depends on I2S_SAMSUNG
54	help
55	  Enable the max98095 audio codec. This is connected via I2S for
56	  audio data and I2C for codec control. At present it only works
57	  with the Samsung I2S driver.
58
59config SOUND_SANDBOX
60	bool "Support sandbox emulated audio codec"
61	depends on SANDBOX && SOUND
62	help
63	  U-Boot sandbox can emulate a sound device using SDL, playing the
64	  sound on the host machine. This option implements the sound_init()
65	  and sound_play() functions for sandbox. Note that you must install
66	  the SDL libraries for this to work.
67
68config SOUND_WM8994
69	bool "Support Wolfson Micro wm8994 audio codec"
70	depends on I2S_SAMSUNG
71	help
72	  Enable the wm8994 audio codec. This is connected via I2S for
73	  audio data and I2C for codec control. At present it only works
74	  with the Samsung I2S driver.
