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.

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.
