2 # SoC audio configuration
6 tristate "ALSA for SoC audio support"
8 select AC97_BUS if SND_SOC_AC97_BUS
9 select SND_JACK if INPUT=y || INPUT=SND
10 select REGMAP_I2C if I2C
11 select REGMAP_SPI if SPI_MASTER
14 If you want ASoC support, you should say Y here and also to the
15 specific driver for your SoC platform below.
17 ASoC provides power efficient ALSA support for embedded battery powered
18 SoC based systems like PDA's, Phones and Personal Media Players.
20 This ASoC audio support can also be built as a module. If so, the module
21 will be called snd-soc-core.
25 config SND_SOC_CACHE_LZO
26 bool "Support LZO compression for register caches"
30 Select this to enable LZO compression for register caches.
31 This will allow machine or CODEC drivers to compress register
32 caches in memory, reducing the memory consumption at the
33 expense of performance. If this is not present and is used
34 the system will fall back to uncompressed caches.
36 Usually it is safe to disable this option, where cache
37 compression in used the rbtree option will typically perform
40 config SND_SOC_AC97_BUS
