| V2 is the update for the 45nm version of the IP used in OMAP3630 | |
| and OMAP4430 | |
| Please note, that by default SmartReflex is only | |
| initialized and not enabled. To enable the automatic voltage | |
| compensation for vdd mpu and vdd core from user space, | |
| user must write 1 to | |
| /debug/smartreflex/sr_<X>/autocomp, | |
| where X is mpu_iva or core for OMAP3. | |
| Optionally autocompensation can be enabled in the kernel | |

| which an be passed as platform data to the smartreflex driver. | |

| help | |
| 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 | |
| yet use clock framework may not work with this option. | |
| If you are booting from another operating system, you | |
| probably do not want this option enabled until your | |
| device drivers work properly. | |
