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.

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).

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.

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().

46 help
47 The DA7219 is an ultra-low-power audio codec with Advanced Accessory
48 Detection (AAD). This driver only supports generation of ACPI tables.
49 It does not support sound output or any of the other codec
50 features.

53 bool "Intel i8254 timer / beeper"
54 depends on SOUND
55 help
56 This enables support for a beeper that uses the i8254 timer chip.
57 This can emit beeps at a fixed frequency. It is possible to control
58 the length of the beeps, by turning a beep on, waiting for a period
59 of time, then turning it off.
60
61 This is quite an old feature, called PIT (Programmable Interval
62 Timer), but is nonetheless still available on modern x86 machines.

65 bool "Intel HDA audio codec"
66 depends on SOUND
67 help
68 Most Intel chips have an HDA (High-definition audio) codec which can
69 be used by U-Boot to play simple beeps. This is also sometimes called
70 Azalia which was the development code-name. It requires setup
71 information in the device tree (see intel-hda.txt).

78 Enable sound output on supported Intel Ivybridge-based boards. This
79 driver uses Intel's High-definition Audio (HDA) architecture,
80 sometimes called Azalia. The audio codec is detected using a
81 semi-automatic mechanism.
