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.

Class 3 implementation of Smartreflex employs continuous hardware
voltage calibration.
config OMAP_RESET_CLOCKS
bool "Reset unused clocks during boot"
depends on ARCH_OMAP
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
bool "Use mpu timer"
depends on ARCH_OMAP1
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.
config OMAP_32K_TIMER
bool "Use 32KHz timer"
depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
default y if (ARCH_OMAP16XX || ARCH_OMAP2PLUS)
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.

Without this option, L2 Auxiliary control register contents are
lost during off-mode entry on HS/EMU devices. This feature
requires support from PPA / boot-loader in HS/EMU devices, which
currently does not exist by default.
