Tony Lindgrenbb13b5f2005-07-10 19:58:18 +0100[diff] [blame]36 help
37 Say Y if you want to reset unused clocks during boot.
38 This option saves power, but assumes all drivers are
39 using the clock framework. Broken drivers that do not
40 yet use clock framework may not work with this option.
41 If you are booting from another operating system, you
42 probably do not want this option enabled until your
43 device drivers work properly.

67 Choose Y here to warn whenever driver initialization logic needs
68 to change the pin multiplexing setup. When there are no warnings
69 printed, it's safe to deselect OMAP_MUX for your product.

95 This timer saves power compared to the OMAP_MPU_TIMER, and has
96 support for no tick during idle. The 32KHz timer provides less
