| Say Y to enable AVS(Adaptive Voltage Scaling) |
| support on OMAP containing the version 1 or |
| version 2 of the SmartReflex IP. |
| V1 is the 65nm version used in OMAP3430. |
| 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 |
| 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 |
| 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. |

| help |
| Select this option if you want to enable the OMAP 32KHz timer. |
| This timer saves power compared to the OMAP_MPU_TIMER, and has |
| support for no tick during idle. The 32KHz timer provides less |
| intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is |
| currently only available for OMAP16XX, 24XX, 34XX, OMAP4/5 and DRA7XX. |
| |
| On OMAP2PLUS this value is only used for CONFIG_HZ and |
| CLOCK_TICK_RATE compile time calculation. |
| The actual timer selection is done in the board file |
| through the (DT_)MACHINE_START structure. |
