  	  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_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.

  	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.

  	help
  	  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.

  	int "Service ID for the support routine to set L2 AUX control"

  	  Select this option if you want to have your system wake up
