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
12 If you want ASoC support, you should say Y here and also to the
13 specific driver for your SoC platform below.
15 ASoC provides power efficient ALSA support for embedded battery powered
16 SoC based systems like PDA's, Phones and Personal Media Players.
18 This ASoC audio support can also be built as a module. If so, the module
19 will be called snd-soc-core.
23 config SND_SOC_CACHE_LZO
24 bool "Support LZO compression for register caches"
28 Select this to enable LZO compression for register caches.
29 This will allow machine or CODEC drivers to compress register
30 caches in memory, reducing the memory consumption at the
31 expense of performance. If this is not present and is used
32 the system will fall back to uncompressed caches.
34 Usually it is safe to disable this option, where cache
35 compression in used the rbtree option will typically perform
38 config SND_SOC_AC97_BUS
