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_POWERDOMAIN
36 bool "Emit debug messages from powerdomain layer"
37 depends on ARCH_OMAP2 || ARCH_OMAP3
40 Say Y here if you want to compile in powerdomain layer
41 debugging messages for OMAP2/3. These messages can
42 provide more detail as to why some powerdomain calls
43 may be failing, and will also emit a descriptive message
44 for every powerdomain register write. However, the
45 extra detail costs some memory.
47 config OMAP_DEBUG_CLOCKDOMAIN
48 bool "Emit debug messages from clockdomain layer"
49 depends on ARCH_OMAP2 || ARCH_OMAP3
52 Say Y here if you want to compile in clockdomain layer
53 debugging messages for OMAP2/3. These messages can
54 provide more detail as to why some clockdomain calls
55 may be failing, and will also emit a descriptive message
56 for every clockdomain register write. However, the
57 extra detail costs some memory.
59 config OMAP_RESET_CLOCKS
60 bool "Reset unused clocks during boot"
63 Say Y if you want to reset unused clocks during boot.
64 This option saves power, but assumes all drivers are
65 using the clock framework. Broken drivers that do not
66 yet use clock framework may not work with this option.
67 If you are booting from another operating system, you
68 probably do not want this option enabled until your
69 device drivers work properly.
72 bool "OMAP bootloader information passing"
76 Say Y, if you have a bootloader which passes information
77 about your board and its peripheral configuration.
79 config OMAP_BOOT_REASON
80 bool "Support for boot reason"
81 depends on OMAP_BOOT_TAG
84 Say Y, if you want to have a procfs entry for reading the boot
87 config OMAP_COMPONENT_VERSION
88 bool "Support for component version display"
89 depends on OMAP_BOOT_TAG && PROC_FS
92 Say Y, if you want to have a procfs entry for reading component
93 versions (supplied by the bootloader) in user-space.
95 config OMAP_GPIO_SWITCH
96 bool "GPIO switch support"
99 Say Y, if you want to have support for reporting of GPIO
100 switches (e.g. cover switches) via sysfs. Your bootloader has
101 to provide information about the switches to the kernel via the
102 ATAG_BOARD mechanism if they're not defined by the board config.
105 bool "OMAP multiplexing support"
109 Pin multiplexing support for OMAP boards. If your bootloader
110 sets the multiplexing correctly, say N. Otherwise, or if unsure,
113 config OMAP_MUX_DEBUG
114 bool "Multiplexing debug output"
117 Makes the multiplexing functions print out a lot of debug info.
118 This is useful if you want to find out the correct values of the
119 multiplexing registers.
121 config OMAP_MUX_WARNINGS
122 bool "Warn about pins the bootloader didn't set up"
126 Choose Y here to warn whenever driver initialization logic needs
127 to change the pin multiplexing setup. When there are no warnings
128 printed, it's safe to deselect OMAP_MUX for your product.
135 Say Y here if you want support for the OMAP Multichannel
136 Buffered Serial Port.
139 bool "MMU framework support"
143 Say Y here if you want to use OMAP MMU framework support for
144 DSP, IVA1.0 and Camera in OMAP1/2.
147 tristate "Mailbox framework support"
151 Say Y here if you want to use OMAP Mailbox framework support for
152 DSP and IVA1.0 in OMAP1/2.
155 prompt "System timer"
156 default OMAP_MPU_TIMER
158 config OMAP_MPU_TIMER
161 Select this option if you want to use the OMAP mpu timer. This
162 timer provides more intra-tick resolution than the 32KHz timer,
163 but consumes more power.
165 config OMAP_32K_TIMER
166 bool "Use 32KHz timer"
167 depends on ARCH_OMAP16XX || ARCH_OMAP24XX || ARCH_OMAP34XX
169 Select this option if you want to enable the OMAP 32KHz timer.
170 This timer saves power compared to the OMAP_MPU_TIMER, and has
171 support for no tick during idle. The 32KHz timer provides less
172 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
173 currently only available for OMAP16XX, 24XX and 34XX.
177 config OMAP_32K_TIMER_HZ
178 int "Kernel internal timer frequency for 32KHz timer"
180 depends on OMAP_32K_TIMER
183 Kernel internal timer frequency should be a divisor of 32768,
187 bool "Use dual-mode timer"
188 depends on ARCH_OMAP16XX || ARCH_OMAP24XX || ARCH_OMAP34XX
190 Select this option if you want to use OMAP Dual-Mode timers.
193 prompt "Low-level debug console UART"
195 default OMAP_LL_DEBUG_UART1
197 config OMAP_LL_DEBUG_UART1
200 config OMAP_LL_DEBUG_UART2
203 config OMAP_LL_DEBUG_UART3
208 config OMAP_SERIAL_WAKE
209 bool "Enable wake-up events for serial ports"
213 Select this option if you want to have your system wake up
214 to data on the serial RX line. This allows you to wake the
215 system from serial console.
