Tony Lindgrenbb13b5f2005-07-10 19:58:18 +010025 help
26 Say Y if you want to reset unused clocks during boot.
27 This option saves power, but assumes all drivers are
28 using the clock framework. Broken drivers that do not
29 yet use clock framework may not work with this option.
30 If you are booting from another operating system, you
31 probably do not want this option enabled until your
32 device drivers work properly.

47 Makes the multiplexing functions print out a lot of debug info.

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

75 Select this option if you want to enable the OMAP 32KHz timer.
76 This timer saves power compared to the OMAP_MPU_TIMER, and has
77 support for no tick during idle. The 32KHz timer provides less
78 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
Tony Lindgrena569c6e2006-04-02 17:46:21 +010079 currently only available for OMAP16XX and 24XX.
