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_/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 bool "Class 3 mode of Smartreflex Implementation" depends on OMAP_SMARTREFLEX && TWL4030_CORE help Say Y to enable Class 3 implementation of Smartreflex 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. config OMAP_MBOX_FWK tristate "Mailbox framework support" depends on ARCH_OMAP help Say Y here if you want to use OMAP Mailbox framework support for DSP, IVA1.0 and IVA2 in OMAP1/2/3. config OMAP_MBOX_KFIFO_SIZE int "Mailbox kfifo default buffer size (bytes)" depends on OMAP_MBOX_FWK default 256 help Specify the default size of mailbox's kfifo buffers (bytes). This can also be changed at runtime (via the mbox_kfifo_size module parameter). config OMAP_IOMMU_IVA2 bool 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 and OMAP4. config OMAP3_L2_AUX_SECURE_SAVE_RESTORE bool "OMAP3 HS/EMU save and restore for L2 AUX control register" depends on ARCH_OMAP3 && PM default n 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. config OMAP3_L2_AUX_SECURE_SERVICE_SET_ID int "Service ID for the support routine to set L2 AUX control" depends on OMAP3_L2_AUX_SECURE_SAVE_RESTORE default 43 help PPA routine service ID for setting L2 auxiliary control register. config OMAP_32K_TIMER_HZ int "Kernel internal timer frequency for 32KHz timer" range 32 1024 depends on OMAP_32K_TIMER default "128" 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 || ARCH_OMAP2PLUS help Select this option if you want to use OMAP Dual-Mode timers. config OMAP_SERIAL_WAKE bool "Enable wake-up events for serial ports" depends on ARCH_OMAP1 && OMAP_MUX default y help 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. choice prompt "OMAP PM layer selection" depends on ARCH_OMAP default OMAP_PM_NOOP config OMAP_PM_NOOP bool "No-op/debug PM layer" endchoice endmenu endif
