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_SMARTREFLEX
60 bool "SmartReflex support"
61 depends on ARCH_OMAP34XX && TWL4030_CORE
63 Say Y if you want to enable SmartReflex.
65 SmartReflex can perform continuous dynamic voltage
66 scaling around the nominal operating point voltage
67 according to silicon characteristics and operating
68 conditions. Enabling SmartReflex reduces power
71 Please note, that by default SmartReflex is only
72 initialized. To enable the automatic voltage
73 compensation for VDD1 and VDD2, user must write 1 to
74 /sys/power/sr_vddX_autocomp, where X is 1 or 2.
76 config OMAP_SMARTREFLEX_TESTING
77 bool "Smartreflex testing support"
78 depends on OMAP_SMARTREFLEX
81 Say Y if you want to enable SmartReflex testing with SW hardcoded
82 NVALUES intead of E-fuse NVALUES set in factory silicon testing.
84 In some devices the E-fuse values have not been set, even though
85 SmartReflex modules are included. Using these hardcoded values set
86 in software, one can test the SmartReflex features without E-fuse.
88 WARNING: Enabling this option may cause your device to hang!
90 config OMAP_RESET_CLOCKS
91 bool "Reset unused clocks during boot"
94 Say Y if you want to reset unused clocks during boot.
95 This option saves power, but assumes all drivers are
96 using the clock framework. Broken drivers that do not
97 yet use clock framework may not work with this option.
98 If you are booting from another operating system, you
99 probably do not want this option enabled until your
100 device drivers work properly.
103 bool "OMAP bootloader information passing"
107 Say Y, if you have a bootloader which passes information
108 about your board and its peripheral configuration.
110 config OMAP_BOOT_REASON
111 bool "Support for boot reason"
112 depends on OMAP_BOOT_TAG
115 Say Y, if you want to have a procfs entry for reading the boot
116 reason in user-space.
118 config OMAP_COMPONENT_VERSION
119 bool "Support for component version display"
120 depends on OMAP_BOOT_TAG && PROC_FS
123 Say Y, if you want to have a procfs entry for reading component
124 versions (supplied by the bootloader) in user-space.
126 config OMAP_GPIO_SWITCH
127 bool "GPIO switch support"
130 Say Y, if you want to have support for reporting of GPIO
131 switches (e.g. cover switches) via sysfs. Your bootloader has
132 to provide information about the switches to the kernel via the
133 ATAG_BOARD mechanism if they're not defined by the board config.
136 bool "OMAP multiplexing support"
140 Pin multiplexing support for OMAP boards. If your bootloader
141 sets the multiplexing correctly, say N. Otherwise, or if unsure,
144 config OMAP_MUX_DEBUG
145 bool "Multiplexing debug output"
148 Makes the multiplexing functions print out a lot of debug info.
149 This is useful if you want to find out the correct values of the
150 multiplexing registers.
152 config OMAP_MUX_WARNINGS
153 bool "Warn about pins the bootloader didn't set up"
157 Choose Y here to warn whenever driver initialization logic needs
158 to change the pin multiplexing setup. When there are no warnings
159 printed, it's safe to deselect OMAP_MUX for your product.
166 Say Y here if you want support for the OMAP Multichannel
167 Buffered Serial Port.
170 bool "MMU framework support"
174 Say Y here if you want to use OMAP MMU framework support for
175 DSP, IVA1.0 and Camera in OMAP1/2.
178 tristate "Mailbox framework support"
182 Say Y here if you want to use OMAP Mailbox framework support for
183 DSP and IVA1.0 in OMAP1/2.
186 prompt "System timer"
187 default OMAP_MPU_TIMER
189 config OMAP_MPU_TIMER
192 Select this option if you want to use the OMAP mpu timer. This
193 timer provides more intra-tick resolution than the 32KHz timer,
194 but consumes more power.
196 config OMAP_32K_TIMER
197 bool "Use 32KHz timer"
198 depends on ARCH_OMAP16XX || ARCH_OMAP24XX || ARCH_OMAP34XX
200 Select this option if you want to enable the OMAP 32KHz timer.
201 This timer saves power compared to the OMAP_MPU_TIMER, and has
202 support for no tick during idle. The 32KHz timer provides less
203 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
204 currently only available for OMAP16XX, 24XX and 34XX.
208 config OMAP_32K_TIMER_HZ
209 int "Kernel internal timer frequency for 32KHz timer"
211 depends on OMAP_32K_TIMER
214 Kernel internal timer frequency should be a divisor of 32768,
218 bool "Use dual-mode timer"
219 depends on ARCH_OMAP16XX || ARCH_OMAP24XX || ARCH_OMAP34XX
221 Select this option if you want to use OMAP Dual-Mode timers.
224 prompt "Low-level debug console UART"
226 default OMAP_LL_DEBUG_UART1
228 config OMAP_LL_DEBUG_UART1
231 config OMAP_LL_DEBUG_UART2
234 config OMAP_LL_DEBUG_UART3
239 config OMAP_SERIAL_WAKE
240 bool "Enable wake-up events for serial ports"
244 Select this option if you want to have your system wake up
245 to data on the serial RX line. This allows you to wake the
246 system from serial console.
