43 Say Y if you want to enable SmartReflex.
44
45 SmartReflex can perform continuous dynamic voltage
46 scaling around the nominal operating point voltage
47 according to silicon characteristics and operating
48 conditions. Enabling SmartReflex reduces power
49 consumption.
50
51 Please note, that by default SmartReflex is only
52 initialized. To enable the automatic voltage
53 compensation for vdd mpu and vdd core from user space,
54 user must write 1 to
55 /debug/voltage/vdd_<X>/smartreflex/autocomp,
56 where X is mpu or core for OMAP3.
57 Optionallly autocompensation can be enabled in the kernel
58 by default during system init via the enable_on_init flag
59 which an be passed as platform data to the smartreflex driver.

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