45 | help |
46 | Say Y if you want to enable SmartReflex. | |
47 | ||
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 |
984aa6db TG |
61 | by default during system init via the enable_on_init flag |
62 | which an be passed as platform data to the smartreflex driver. | |

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. | |
