46 Say Y if you want to enable SmartReflex.

48 SmartReflex can perform continuous dynamic voltage
49 scaling around the nominal operating point voltage
50 according to silicon characteristics and operating
51 conditions. Enabling SmartReflex reduces power
52 consumption.
53
54 Please note, that by default SmartReflex is only
55 initialized. To enable the automatic voltage
56 compensation for vdd mpu and vdd core from user space,
57 user must write 1 to
58 /debug/voltage/vdd_<X>/smartreflex/autocomp,
59 where X is mpu or core for OMAP3.
19f52522 60 Optionally autocompensation can be enabled in the kernel

76 help
77 Say Y if you want to reset unused clocks during boot.
78 This option saves power, but assumes all drivers are
79 using the clock framework. Broken drivers that do not
80 yet use clock framework may not work with this option.
81 If you are booting from another operating system, you
82 probably do not want this option enabled until your
83 device drivers work properly.
