22 config OMAP_DEBUG_DEVICES
25 For debug cards on TI reference boards.
27 config OMAP_DEBUG_LEDS
29 depends on OMAP_DEBUG_DEVICES
30 default y if LEDS || LEDS_OMAP_DEBUG
32 config OMAP_DEBUG_POWERDOMAIN
33 bool "Emit debug messages from powerdomain layer"
34 depends on ARCH_OMAP2 || ARCH_OMAP3
37 Say Y here if you want to compile in powerdomain layer
38 debugging messages for OMAP2/3. These messages can
39 provide more detail as to why some powerdomain calls
40 may be failing, and will also emit a descriptive message
41 for every powerdomain register write. However, the
42 extra detail costs some memory.
44 config OMAP_DEBUG_CLOCKDOMAIN
45 bool "Emit debug messages from clockdomain layer"
46 depends on ARCH_OMAP2 || ARCH_OMAP3
49 Say Y here if you want to compile in clockdomain layer
50 debugging messages for OMAP2/3. These messages can
51 provide more detail as to why some clockdomain calls
52 may be failing, and will also emit a descriptive message
53 for every clockdomain register write. However, the
54 extra detail costs some memory.
56 config OMAP_RESET_CLOCKS
57 bool "Reset unused clocks during boot"
60 Say Y if you want to reset unused clocks during boot.
61 This option saves power, but assumes all drivers are
62 using the clock framework. Broken drivers that do not
63 yet use clock framework may not work with this option.
64 If you are booting from another operating system, you
65 probably do not want this option enabled until your
66 device drivers work properly.
69 bool "OMAP multiplexing support"
73 Pin multiplexing support for OMAP boards. If your bootloader
74 sets the multiplexing correctly, say N. Otherwise, or if unsure,
78 bool "Multiplexing debug output"
81 Makes the multiplexing functions print out a lot of debug info.
82 This is useful if you want to find out the correct values of the
83 multiplexing registers.
85 config OMAP_MUX_WARNINGS
86 bool "Warn about pins the bootloader didn't set up"
90 Choose Y here to warn whenever driver initialization logic needs
91 to change the pin multiplexing setup. When there are no warnings
92 printed, it's safe to deselect OMAP_MUX for your product.
99 Say Y here if you want support for the OMAP Multichannel
100 Buffered Serial Port.
103 prompt "System timer"
104 default OMAP_MPU_TIMER
106 config OMAP_MPU_TIMER
109 Select this option if you want to use the OMAP mpu timer. This
110 timer provides more intra-tick resolution than the 32KHz timer,
111 but consumes more power.
113 config OMAP_32K_TIMER
114 bool "Use 32KHz timer"
115 depends on ARCH_OMAP16XX || ARCH_OMAP24XX
117 Select this option if you want to enable the OMAP 32KHz timer.
118 This timer saves power compared to the OMAP_MPU_TIMER, and has
119 support for no tick during idle. The 32KHz timer provides less
120 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
121 currently only available for OMAP16XX and 24XX.
125 config OMAP_32K_TIMER_HZ
126 int "Kernel internal timer frequency for 32KHz timer"
128 depends on OMAP_32K_TIMER
131 Kernel internal timer frequency should be a divisor of 32768,
135 bool "Use dual-mode timer"
136 depends on ARCH_OMAP16XX || ARCH_OMAP24XX
138 Select this option if you want to use OMAP Dual-Mode timers.
141 prompt "Low-level debug console UART"
143 default OMAP_LL_DEBUG_UART1
145 config OMAP_LL_DEBUG_UART1
148 config OMAP_LL_DEBUG_UART2
151 config OMAP_LL_DEBUG_UART3
156 config OMAP_SERIAL_WAKE
157 bool "Enable wake-up events for serial ports"
161 Select this option if you want to have your system wake up
162 to data on the serial RX line. This allows you to wake the
163 system from serial console.
