22 config OMAP_RESET_CLOCKS
23 bool "Reset unused clocks during boot"
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.
35 bool "OMAP bootloader information passing"
39 Say Y, if you have a bootloader which passes information
40 about your board and its peripheral configuration.
42 config OMAP_BOOT_REASON
43 bool "Support for boot reason"
44 depends on OMAP_BOOT_TAG
47 Say Y, if you want to have a procfs entry for reading the boot
50 config OMAP_COMPONENT_VERSION
51 bool "Support for component version display"
52 depends on OMAP_BOOT_TAG && PROC_FS
55 Say Y, if you want to have a procfs entry for reading component
56 versions (supplied by the bootloader) in user-space.
58 config OMAP_GPIO_SWITCH
59 bool "GPIO switch support"
60 depends on OMAP_BOOT_TAG
63 Say Y, if you want to have support for input layer reporting
64 of GPIO switches (e.g. cover switches). Your bootloader has to
65 provide information about the switches to the kernel via the
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.
95 bool "STI/XTI support"
96 depends on ARCH_OMAP16XX || ARCH_OMAP24XX
99 config OMAP_STI_CONSOLE
100 bool "STI console support"
103 This enables a console driver by way of STI/XTI.
106 prompt "System timer"
107 default OMAP_MPU_TIMER
109 config OMAP_MPU_TIMER
112 Select this option if you want to use the OMAP mpu timer. This
113 timer provides more intra-tick resolution than the 32KHz timer,
114 but consumes more power.
116 config OMAP_32K_TIMER
117 bool "Use 32KHz timer"
118 depends on ARCH_OMAP16XX || ARCH_OMAP24XX
120 Select this option if you want to enable the OMAP 32KHz timer.
121 This timer saves power compared to the OMAP_MPU_TIMER, and has
122 support for no tick during idle. The 32KHz timer provides less
123 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
124 currently only available for OMAP16XX and 24XX.
128 config OMAP_32K_TIMER_HZ
129 int "Kernel internal timer frequency for 32KHz timer"
131 depends on OMAP_32K_TIMER
134 Kernel internal timer frequency should be a divisor of 32768,
138 bool "Use dual-mode timer"
139 depends on ARCH_OMAP16XX
141 Select this option if you want to use OMAP Dual-Mode timers.
144 prompt "Low-level debug console UART"
146 default OMAP_LL_DEBUG_UART1
148 config OMAP_LL_DEBUG_UART1
151 config OMAP_LL_DEBUG_UART2
154 config OMAP_LL_DEBUG_UART3
159 config OMAP_SERIAL_WAKE
160 bool "Enable wake-up events for serial ports"
164 Select this option if you want to have your system wake up
165 to data on the serial RX line. This allows you to wake the
166 system from serial console.
