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
bool "OMAP multiplexing support"
depends on ARCH_OMAP
default y
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
default y
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.
choice
prompt "System timer"
default OMAP_MPU_TIMER
config OMAP_MPU_TIMER
bool "Use mpu timer"
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
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 OMAP-16xx.

config OMAP_32K_TIMER_HZ
int "Kernel internal timer frequency for 32KHz timer"

depends on OMAP_32K_TIMER

help
Kernel internal timer frequency should be a divisor of 32768,
such as 64 or 128.
config OMAP_DM_TIMER
bool "Use dual-mode timer"
depends on ARCH_OMAP16XX
help
Select this option if you want to use OMAP Dual-Mode timers.

Select this option if you want to have your system wake up
to data on the serial RX line. This allows you to wake the
system from serial console.
