bool "SmartReflex support"
depends on (ARCH_OMAP3 || ARCH_OMAP4) && PM
help
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.
config OMAP_SMARTREFLEX_CLASS3

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_MUX

help
Pin multiplexing support for OMAP boards. If your bootloader
sets the multiplexing correctly, say N. Otherwise, or if unsure,
say Y.
config OMAP_MUX_DEBUG
bool "Multiplexing debug output"
depends on OMAP_MUX
help
Makes the multiplexing functions print out a lot of debug info.
This is useful if you want to find out the correct values of the
multiplexing registers.
config OMAP_MUX_WARNINGS
bool "Warn about pins the bootloader didn't set up"
depends on OMAP_MUX

help
Choose Y here to warn whenever driver initialization logic needs
to change the pin multiplexing setup. When there are no warnings
printed, it's safe to deselect OMAP_MUX for your product.

Buffered Serial Port.

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 and OMAP4.
