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
|
|
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.
