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.
117 bool "STI/XTI support"
118 depends on ARCH_OMAP16XX || ARCH_OMAP24XX
121 config OMAP_STI_CONSOLE
122 bool "STI console support"
125 This enables a console driver by way of STI/XTI.
132 Say Y here if you want support for the OMAP Multichannel
133 Buffered Serial Port.
136 tristate "MMU framework support"
140 Say Y here if you want to use OMAP MMU framework support for
141 DSP, IVA1.0 and Camera in OMAP1/2.
144 tristate "Mailbox framework support"
148 Say Y here if you want to use OMAP Mailbox framework support for
149 DSP and IVA1.0 in OMAP1/2.
152 prompt "System timer"
153 default OMAP_MPU_TIMER
155 config OMAP_MPU_TIMER
158 Select this option if you want to use the OMAP mpu timer. This
159 timer provides more intra-tick resolution than the 32KHz timer,
160 but consumes more power.
162 config OMAP_32K_TIMER
163 bool "Use 32KHz timer"
164 depends on ARCH_OMAP16XX || ARCH_OMAP24XX || ARCH_OMAP34XX
166 Select this option if you want to enable the OMAP 32KHz timer.
167 This timer saves power compared to the OMAP_MPU_TIMER, and has
168 support for no tick during idle. The 32KHz timer provides less
169 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
170 currently only available for OMAP16XX, 24XX and 34XX.
174 config OMAP_32K_TIMER_HZ
175 int "Kernel internal timer frequency for 32KHz timer"
177 depends on OMAP_32K_TIMER
180 Kernel internal timer frequency should be a divisor of 32768,
184 bool "Use dual-mode timer"
185 depends on ARCH_OMAP16XX || ARCH_OMAP24XX || ARCH_OMAP34XX
187 Select this option if you want to use OMAP Dual-Mode timers.
190 prompt "Low-level debug console UART"
192 default OMAP_LL_DEBUG_UART1
194 config OMAP_LL_DEBUG_UART1
197 config OMAP_LL_DEBUG_UART2
200 config OMAP_LL_DEBUG_UART3
205 config OMAP_SERIAL_WAKE
206 bool "Enable wake-up events for serial ports"
210 Select this option if you want to have your system wake up
211 to data on the serial RX line. This allows you to wake the
212 system from serial console.
