user must write 1 to

Optionally autocompensation can be enabled in the kernel

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 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.
