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"
62 Say Y, if you want to have support for reporting of GPIO
63 switches (e.g. cover switches) via sysfs. Your bootloader has
64 to provide information about the switches to the kernel via the
65 ATAG_BOARD mechanism if they're not defined by the board config.
68 bool "OMAP multiplexing support"
72 Pin multiplexing support for OMAP boards. If your bootloader
73 sets the multiplexing correctly, say N. Otherwise, or if unsure,
77 bool "Multiplexing debug output"
80 Makes the multiplexing functions print out a lot of debug info.
81 This is useful if you want to find out the correct values of the
82 multiplexing registers.
84 config OMAP_MUX_WARNINGS
85 bool "Warn about pins the bootloader didn't set up"
89 Choose Y here to warn whenever driver initialization logic needs
90 to change the pin multiplexing setup. When there are no warnings
91 printed, it's safe to deselect OMAP_MUX for your product.
94 bool "STI/XTI support"
95 depends on ARCH_OMAP16XX || ARCH_OMAP24XX
98 config OMAP_STI_CONSOLE
99 bool "STI console support"
102 This enables a console driver by way of STI/XTI.
109 Say Y here if you want support for the OMAP Multichannel
110 Buffered Serial Port.
113 prompt "System timer"
114 default OMAP_MPU_TIMER
116 config OMAP_MPU_TIMER
119 Select this option if you want to use the OMAP mpu timer. This
120 timer provides more intra-tick resolution than the 32KHz timer,
121 but consumes more power.
123 config OMAP_32K_TIMER
124 bool "Use 32KHz timer"
125 depends on ARCH_OMAP16XX || ARCH_OMAP24XX
127 Select this option if you want to enable the OMAP 32KHz timer.
128 This timer saves power compared to the OMAP_MPU_TIMER, and has
129 support for no tick during idle. The 32KHz timer provides less
130 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
131 currently only available for OMAP16XX and 24XX.
135 config OMAP_32K_TIMER_HZ
136 int "Kernel internal timer frequency for 32KHz timer"
138 depends on OMAP_32K_TIMER
141 Kernel internal timer frequency should be a divisor of 32768,
145 bool "Use dual-mode timer"
146 depends on ARCH_OMAP16XX || ARCH_OMAP24XX
148 Select this option if you want to use OMAP Dual-Mode timers.
151 prompt "Low-level debug console UART"
153 default OMAP_LL_DEBUG_UART1
155 config OMAP_LL_DEBUG_UART1
158 config OMAP_LL_DEBUG_UART2
161 config OMAP_LL_DEBUG_UART3
166 config OMAP_SERIAL_WAKE
167 bool "Enable wake-up events for serial ports"
171 Select this option if you want to have your system wake up
172 to data on the serial RX line. This allows you to wake the
173 system from serial console.
