1config SOUND 2 bool "Enable sound support" 3 help 4 Support making sounds through an audio codec. This is normally a 5 beep at a chosen frequency for a selected length of time. However 6 the drivers support playing arbitrary sound samples using a 7 PCM interface. 8 9 Note: At present the sound setup is somewhat tangled up in that the 10 audio codecs are called from the sound-i2s code. This could be 11 converted to driver model. 12 13config I2S 14 bool "Enable I2S support" 15 depends on SOUND 16 help 17 I2S is a serial bus often used to transmit audio data from the 18 SoC to the audio codec. This option enables sound support using 19 I2S. It calls either of the two supported codecs (no use is made 20 of driver model at present). 21 22config I2S_SAMSUNG 23 bool "Enable I2C support for Samsung SoCs" 24 depends on SOUND 25 help 26 Samsung Exynos SoCs support an I2S interface for sending audio 27 data to an audio codec. This option enables support for this, 28 using one of the available audio codec drivers. Enabling this 29 option provides an implementation for sound_init() and 30 sound_play(). 31 32config SOUND_MAX98095 33 bool "Support Maxim max98095 audio codec" 34 depends on I2S_SAMSUNG 35 help 36 Enable the max98095 audio codec. This is connected via I2S for 37 audio data and I2C for codec control. At present it only works 38 with the Samsung I2S driver. 39 40config SOUND_WM8994 41 bool "Support Wolfson Micro wm8994 audio codec" 42 depends on I2S_SAMSUNG 43 help 44 Enable the wm8994 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. 47
