30 config OMAP_DEBUG_DEVICES
33 For debug cards on TI reference boards.
35 config OMAP_DEBUG_LEDS
37 depends on OMAP_DEBUG_DEVICES
38 default y if LEDS || LEDS_OMAP_DEBUG
40 config OMAP_DEBUG_POWERDOMAIN
41 bool "Emit debug messages from powerdomain layer"
42 depends on ARCH_OMAP2 || ARCH_OMAP3
45 Say Y here if you want to compile in powerdomain layer
46 debugging messages for OMAP2/3. These messages can
47 provide more detail as to why some powerdomain calls
48 may be failing, and will also emit a descriptive message
49 for every powerdomain register write. However, the
50 extra detail costs some memory.
52 config OMAP_DEBUG_CLOCKDOMAIN
53 bool "Emit debug messages from clockdomain layer"
54 depends on ARCH_OMAP2 || ARCH_OMAP3
57 Say Y here if you want to compile in clockdomain layer
58 debugging messages for OMAP2/3. These messages can
59 provide more detail as to why some clockdomain calls
60 may be failing, and will also emit a descriptive message
61 for every clockdomain register write. However, the
62 extra detail costs some memory.
64 config OMAP_RESET_CLOCKS
65 bool "Reset unused clocks during boot"
68 Say Y if you want to reset unused clocks during boot.
69 This option saves power, but assumes all drivers are
70 using the clock framework. Broken drivers that do not
71 yet use clock framework may not work with this option.
72 If you are booting from another operating system, you
73 probably do not want this option enabled until your
74 device drivers work properly.
77 bool "OMAP bootloader information passing"
81 Say Y, if you have a bootloader which passes information
82 about your board and its peripheral configuration.
84 config OMAP_BOOT_REASON
85 bool "Support for boot reason"
86 depends on OMAP_BOOT_TAG
89 Say Y, if you want to have a procfs entry for reading the boot
92 config OMAP_COMPONENT_VERSION
93 bool "Support for component version display"
94 depends on OMAP_BOOT_TAG && PROC_FS
97 Say Y, if you want to have a procfs entry for reading component
98 versions (supplied by the bootloader) in user-space.
100 config OMAP_GPIO_SWITCH
101 bool "GPIO switch support"
104 Say Y, if you want to have support for reporting of GPIO
105 switches (e.g. cover switches) via sysfs. Your bootloader has
106 to provide information about the switches to the kernel via the
107 ATAG_BOARD mechanism if they're not defined by the board config.
110 bool "OMAP multiplexing support"
114 Pin multiplexing support for OMAP boards. If your bootloader
115 sets the multiplexing correctly, say N. Otherwise, or if unsure,
118 config OMAP_MUX_DEBUG
119 bool "Multiplexing debug output"
122 Makes the multiplexing functions print out a lot of debug info.
123 This is useful if you want to find out the correct values of the
124 multiplexing registers.
126 config OMAP_MUX_WARNINGS
127 bool "Warn about pins the bootloader didn't set up"
131 Choose Y here to warn whenever driver initialization logic needs
132 to change the pin multiplexing setup. When there are no warnings
133 printed, it's safe to deselect OMAP_MUX for your product.
140 Say Y here if you want support for the OMAP Multichannel
141 Buffered Serial Port.
144 tristate "Mailbox framework support"
148 Say Y here if you want to use OMAP Mailbox framework support for
149 DSP, IVA1.0 and IVA2 in OMAP1/2/3.
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.
