| Say Y if you want to enable SmartReflex. |
| |
| SmartReflex can perform continuous dynamic voltage |
| scaling around the nominal operating point voltage |
| according to silicon characteristics and operating |
| conditions. Enabling SmartReflex reduces power |
| consumption. |
| |
| Please note, that by default SmartReflex is only |
| initialized. To enable the automatic voltage |
| compensation for vdd mpu and vdd core from user space, |
| user must write 1 to |
| /debug/voltage/vdd_<X>/smartreflex/autocomp, |
| where X is mpu or core for OMAP3. |
| Optionally autocompensation can be enabled in the kernel |
| by default during system init via the enable_on_init flag |
| which an be passed as platform data to the smartreflex driver. |

| Say Y if you want to reset unused clocks during boot. |
| This option saves power, but assumes all drivers are |
| using the clock framework. Broken drivers that do not |
