23 config OMAP_DEBUG_LEDS
26 For debug card leds on TI reference boards.
28 config OMAP_RESET_CLOCKS
29 bool "Reset unused clocks during boot"
32 Say Y if you want to reset unused clocks during boot.
33 This option saves power, but assumes all drivers are
34 using the clock framework. Broken drivers that do not
35 yet use clock framework may not work with this option.
36 If you are booting from another operating system, you
37 probably do not want this option enabled until your
38 device drivers work properly.
41 bool "OMAP multiplexing support"
45 Pin multiplexing support for OMAP boards. If your bootloader
46 sets the multiplexing correctly, say N. Otherwise, or if unsure,
50 bool "Multiplexing debug output"
53 Makes the multiplexing functions print out a lot of debug info.
54 This is useful if you want to find out the correct values of the
55 multiplexing registers.
57 config OMAP_MUX_WARNINGS
58 bool "Warn about pins the bootloader didn't set up"
62 Choose Y here to warn whenever driver initialization logic needs
63 to change the pin multiplexing setup. When there are no warnings
64 printed, it's safe to deselect OMAP_MUX for your product.
71 Say Y here if you want support for the OMAP Multichannel
76 default OMAP_MPU_TIMER
81 Select this option if you want to use the OMAP mpu timer. This
82 timer provides more intra-tick resolution than the 32KHz timer,
83 but consumes more power.
86 bool "Use 32KHz timer"
87 depends on ARCH_OMAP16XX || ARCH_OMAP24XX
89 Select this option if you want to enable the OMAP 32KHz timer.
90 This timer saves power compared to the OMAP_MPU_TIMER, and has
91 support for no tick during idle. The 32KHz timer provides less
92 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
93 currently only available for OMAP16XX and 24XX.
97 config OMAP_32K_TIMER_HZ
98 int "Kernel internal timer frequency for 32KHz timer"
100 depends on OMAP_32K_TIMER
103 Kernel internal timer frequency should be a divisor of 32768,
107 bool "Use dual-mode timer"
108 depends on ARCH_OMAP16XX || ARCH_OMAP24XX
110 Select this option if you want to use OMAP Dual-Mode timers.
113 prompt "Low-level debug console UART"
115 default OMAP_LL_DEBUG_UART1
117 config OMAP_LL_DEBUG_UART1
120 config OMAP_LL_DEBUG_UART2
123 config OMAP_LL_DEBUG_UART3
128 config OMAP_SERIAL_WAKE
129 bool "Enable wake-up events for serial ports"
133 Select this option if you want to have your system wake up
134 to data on the serial RX line. This allows you to wake the
135 system from serial console.
