35 help
36 Say Y if you want to reset unused clocks during boot.
37 This option saves power, but assumes all drivers are
38 using the clock framework. Broken drivers that do not
39 yet use clock framework may not work with this option.
40 If you are booting from another operating system, you
41 probably do not want this option enabled until your
42 device drivers work properly.

50 sets the multiplexing correctly, say N. Otherwise, or if unsure,

57 Makes the multiplexing functions print out a lot of debug info.
58 This is useful if you want to find out the correct values of the
59 multiplexing registers.

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

92 help
93 Select this option if you want to enable the OMAP 32KHz timer.
94 This timer saves power compared to the OMAP_MPU_TIMER, and has
95 support for no tick during idle. The 32KHz timer provides less
96 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
a569c6ec 97 currently only available for OMAP16XX and 24XX.
