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. |

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. |

config OMAP_MPU_TIMER |

help |

Select this option if you want to use the OMAP mpu timer. This |
|
timer provides more intra-tick resolution than the 32KHz timer, |
|
but consumes more power. |

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. |
