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