|  | 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. |

|  | 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. |
