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.
19
20	  This ASoC audio support can also be built as a module.  If so, the module
21	  will be called snd-soc-core.

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.
35
36	   Usually it is safe to disable this option, where cache
37	   compression in used the rbtree option will typically perform
38	   better.
