To enable the automatic voltage 37 compensation for vdd mpu and vdd core from user space, 38 user must write 1 to 39 /debug/smartreflex/sr_<X>/autocomp, 40 where X is mpu_iva or core for OMAP3. 41 Optionally autocompensation can be enabled in the kernel 42 by default during system init via the enable_on_init flag 43 which an be passed as platform data to the smartreflex driver. 44 45config POWER_AVS_OMAP_CLASS3 46 bool "Class 3 mode of Smartreflex Implementation" 47 depends on POWER_AVS_OMAP && TWL4030_CORE 48 help 49 Say Y to enable Class 3 implementation of Smartreflex 50 51 Class 3 implementation of Smartreflex employs continuous hardware 52 voltage calibration. 53 54config OMAP_RESET_CLOCKS 55 bool "Reset unused clocks during boot" 56 depends on ARCH_OMAP 57 help 58 Say Y if you want to reset unused clocks during boot. 59 This option saves power, but assumes all drivers are 60 using the clock framework. Broken drivers that do not 61 yet use clock framework may not work with this option. 62 If you are booting from another operating system, you 63 probably do not want this option enabled until your 64 device drivers work properly. 65 66config OMAP_MUX 67 bool "OMAP multiplexing support" 68 depends on ARCH_OMAP 69 default y 70 help 71 Pin multiplexing support for OMAP boards.
