25 config OMAP_DEBUG_DEVICES
28 For debug cards on TI reference boards.
30 config OMAP_DEBUG_LEDS
32 depends on OMAP_DEBUG_DEVICES
33 default y if LEDS || LEDS_OMAP_DEBUG
35 config OMAP_DEBUG_SRAM_PATCH
36 bool "Extra sanity checking for SRAM patch code"
40 Say Y here if you want the kernel to use extra caution
41 in patching SRAM virtual addresses. If you are
42 confident in your SRAM code, disabling this will save
45 config OMAP_RESET_CLOCKS
46 bool "Reset unused clocks during boot"
49 Say Y if you want to reset unused clocks during boot.
50 This option saves power, but assumes all drivers are
51 using the clock framework. Broken drivers that do not
52 yet use clock framework may not work with this option.
53 If you are booting from another operating system, you
54 probably do not want this option enabled until your
55 device drivers work properly.
58 bool "OMAP bootloader information passing"
62 Say Y, if you have a bootloader which passes information
63 about your board and its peripheral configuration.
65 config OMAP_BOOT_REASON
66 bool "Support for boot reason"
67 depends on OMAP_BOOT_TAG
70 Say Y, if you want to have a procfs entry for reading the boot
73 config OMAP_COMPONENT_VERSION
74 bool "Support for component version display"
75 depends on OMAP_BOOT_TAG && PROC_FS
78 Say Y, if you want to have a procfs entry for reading component
79 versions (supplied by the bootloader) in user-space.
81 config OMAP_GPIO_SWITCH
82 bool "GPIO switch support"
85 Say Y, if you want to have support for reporting of GPIO
86 switches (e.g. cover switches) via sysfs. Your bootloader has
87 to provide information about the switches to the kernel via the
88 ATAG_BOARD mechanism if they're not defined by the board config.
91 bool "OMAP multiplexing support"
95 Pin multiplexing support for OMAP boards. If your bootloader
96 sets the multiplexing correctly, say N. Otherwise, or if unsure,
100 bool "Multiplexing debug output"
103 Makes the multiplexing functions print out a lot of debug info.
104 This is useful if you want to find out the correct values of the
105 multiplexing registers.
107 config OMAP_MUX_WARNINGS
108 bool "Warn about pins the bootloader didn't set up"
112 Choose Y here to warn whenever driver initialization logic needs
113 to change the pin multiplexing setup. When there are no warnings
114 printed, it's safe to deselect OMAP_MUX for your product.
121 Say Y here if you want support for the OMAP Multichannel
122 Buffered Serial Port.
125 bool "MMU framework support"
129 Say Y here if you want to use OMAP MMU framework support for
130 DSP, IVA1.0 and Camera in OMAP1/2.
133 tristate "Mailbox framework support"
137 Say Y here if you want to use OMAP Mailbox framework support for
138 DSP and IVA1.0 in OMAP1/2.
141 prompt "System timer"
142 default OMAP_MPU_TIMER
144 config OMAP_MPU_TIMER
147 Select this option if you want to use the OMAP mpu timer. This
148 timer provides more intra-tick resolution than the 32KHz timer,
149 but consumes more power.
151 config OMAP_32K_TIMER
152 bool "Use 32KHz timer"
153 depends on ARCH_OMAP16XX || ARCH_OMAP24XX || ARCH_OMAP34XX
155 Select this option if you want to enable the OMAP 32KHz timer.
156 This timer saves power compared to the OMAP_MPU_TIMER, and has
157 support for no tick during idle. The 32KHz timer provides less
158 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
159 currently only available for OMAP16XX, 24XX and 34XX.
163 config OMAP_32K_TIMER_HZ
164 int "Kernel internal timer frequency for 32KHz timer"
166 depends on OMAP_32K_TIMER
169 Kernel internal timer frequency should be a divisor of 32768,
173 bool "Use dual-mode timer"
174 depends on ARCH_OMAP16XX || ARCH_OMAP24XX || ARCH_OMAP34XX
176 Select this option if you want to use OMAP Dual-Mode timers.
179 prompt "Low-level debug console UART"
181 default OMAP_LL_DEBUG_UART1
183 config OMAP_LL_DEBUG_UART1
186 config OMAP_LL_DEBUG_UART2
189 config OMAP_LL_DEBUG_UART3
194 config OMAP_SERIAL_WAKE
195 bool "Enable wake-up events for serial ports"
199 Select this option if you want to have your system wake up
200 to data on the serial RX line. This allows you to wake the
201 system from serial console.
