22 config OMAP_RESET_CLOCKS
23 bool "Reset unused clocks during boot"
27 Say Y if you want to reset unused clocks during boot.
28 This option saves power, but assumes all drivers are
29 using the clock framework. Broken drivers that do not
30 yet use clock framework may not work with this option.
31 If you are booting from another operating system, you
32 probably do not want this option enabled until your
33 device drivers work properly.
36 bool "OMAP multiplexing support"
40 Pin multiplexing support for OMAP boards. If your bootloader
41 sets the multiplexing correctly, say N. Otherwise, or if unsure,
45 bool "Multiplexing debug output"
49 Makes the multiplexing functions print out a lot of debug info.
50 This is useful if you want to find out the correct values of the
51 multiplexing registers.
53 config OMAP_MUX_WARNINGS
54 bool "Warn about pins the bootloader didn't set up"
58 Choose Y here to warn whenever driver initialization logic needs
59 to change the pin multiplexing setup. When there are no warnings
60 printed, it's safe to deselect OMAP_MUX for your product.
64 default OMAP_MPU_TIMER
69 Select this option if you want to use the OMAP mpu timer. This
70 timer provides more intra-tick resolution than the 32KHz timer,
71 but consumes more power.
74 bool "Use 32KHz timer"
75 depends on ARCH_OMAP16XX
77 Select this option if you want to enable the OMAP 32KHz timer.
78 This timer saves power compared to the OMAP_MPU_TIMER, and has
79 support for no tick during idle. The 32KHz timer provides less
80 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
81 currently only available for OMAP-16xx.
85 config OMAP_32K_TIMER_HZ
86 int "Kernel internal timer frequency for 32KHz timer"
88 depends on OMAP_32K_TIMER
91 Kernel internal timer frequency should be a divisor of 32768,
95 bool "Use dual-mode timer"
97 depends on ARCH_OMAP16XX
99 Select this option if you want to use OMAP Dual-Mode timers.
102 prompt "Low-level debug console UART"
104 default OMAP_LL_DEBUG_UART1
106 config OMAP_LL_DEBUG_UART1
109 config OMAP_LL_DEBUG_UART2
112 config OMAP_LL_DEBUG_UART3
117 config OMAP_SERIAL_WAKE
118 bool "Enable wake-up events for serial ports"
122 Select this option if you want to have your system wake up
123 to data on the serial RX line. This allows you to wake the
124 system from serial console.
