| 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. |

| 29 | ---help--- |
| 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. |
