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_RESET_CLOCKS
33 bool "Reset unused clocks during boot"
36 Say Y if you want to reset unused clocks during boot.
37 This option saves power, but assumes all drivers are
38 using the clock framework. Broken drivers that do not
39 yet use clock framework may not work with this option.
40 If you are booting from another operating system, you
41 probably do not want this option enabled until your
42 device drivers work properly.
45 bool "OMAP bootloader information passing"
49 Say Y, if you have a bootloader which passes information
50 about your board and its peripheral configuration.
52 config OMAP_BOOT_REASON
53 bool "Support for boot reason"
54 depends on OMAP_BOOT_TAG
57 Say Y, if you want to have a procfs entry for reading the boot
60 config OMAP_COMPONENT_VERSION
61 bool "Support for component version display"
62 depends on OMAP_BOOT_TAG && PROC_FS
65 Say Y, if you want to have a procfs entry for reading component
66 versions (supplied by the bootloader) in user-space.
68 config OMAP_GPIO_SWITCH
69 bool "GPIO switch support"
72 Say Y, if you want to have support for reporting of GPIO
73 switches (e.g. cover switches) via sysfs. Your bootloader has
74 to provide information about the switches to the kernel via the
75 ATAG_BOARD mechanism if they're not defined by the board config.
78 bool "OMAP multiplexing support"
82 Pin multiplexing support for OMAP boards. If your bootloader
83 sets the multiplexing correctly, say N. Otherwise, or if unsure,
87 bool "Multiplexing debug output"
90 Makes the multiplexing functions print out a lot of debug info.
91 This is useful if you want to find out the correct values of the
92 multiplexing registers.
94 config OMAP_MUX_WARNINGS
95 bool "Warn about pins the bootloader didn't set up"
99 Choose Y here to warn whenever driver initialization logic needs
100 to change the pin multiplexing setup. When there are no warnings
101 printed, it's safe to deselect OMAP_MUX for your product.
104 bool "STI/XTI support"
105 depends on ARCH_OMAP16XX || ARCH_OMAP24XX
108 config OMAP_STI_CONSOLE
109 bool "STI console support"
112 This enables a console driver by way of STI/XTI.
119 Say Y here if you want support for the OMAP Multichannel
120 Buffered Serial Port.
123 prompt "System timer"
124 default OMAP_MPU_TIMER
126 config OMAP_MPU_TIMER
129 Select this option if you want to use the OMAP mpu timer. This
130 timer provides more intra-tick resolution than the 32KHz timer,
131 but consumes more power.
133 config OMAP_32K_TIMER
134 bool "Use 32KHz timer"
135 depends on ARCH_OMAP16XX || ARCH_OMAP24XX
137 Select this option if you want to enable the OMAP 32KHz timer.
138 This timer saves power compared to the OMAP_MPU_TIMER, and has
139 support for no tick during idle. The 32KHz timer provides less
140 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
141 currently only available for OMAP16XX and 24XX.
145 config OMAP_32K_TIMER_HZ
146 int "Kernel internal timer frequency for 32KHz timer"
148 depends on OMAP_32K_TIMER
151 Kernel internal timer frequency should be a divisor of 32768,
155 bool "Use dual-mode timer"
156 depends on ARCH_OMAP16XX || ARCH_OMAP24XX
158 Select this option if you want to use OMAP Dual-Mode timers.
161 prompt "Low-level debug console UART"
163 default OMAP_LL_DEBUG_UART1
165 config OMAP_LL_DEBUG_UART1
168 config OMAP_LL_DEBUG_UART2
171 config OMAP_LL_DEBUG_UART3
176 config OMAP_SERIAL_WAKE
177 bool "Enable wake-up events for serial ports"
181 Select this option if you want to have your system wake up
182 to data on the serial RX line. This allows you to wake the
183 system from serial console.
