42 | help |
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. | |

73 | help |
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 | |
