29 config OMAP_DEBUG_DEVICES
32 For debug cards on TI reference boards.
34 config OMAP_DEBUG_LEDS
36 depends on OMAP_DEBUG_DEVICES
37 default y if LEDS_CLASS
39 config OMAP_SMARTREFLEX
40 bool "SmartReflex support"
41 depends on (ARCH_OMAP3 || ARCH_OMAP4) && PM
43 Say Y if you want to enable SmartReflex.
45 SmartReflex can perform continuous dynamic voltage
46 scaling around the nominal operating point voltage
47 according to silicon characteristics and operating
48 conditions. Enabling SmartReflex reduces power
51 Please note, that by default SmartReflex is only
52 initialized. To enable the automatic voltage
53 compensation for vdd mpu and vdd core from user space,
55 /debug/voltage/vdd_<X>/smartreflex/autocomp,
56 where X is mpu or core for OMAP3.
57 Optionallly autocompensation can be enabled in the kernel
58 by default during system init via the enable_on_init flag
59 which an be passed as platform data to the smartreflex driver.
61 config OMAP_SMARTREFLEX_CLASS3
62 bool "Class 3 mode of Smartreflex Implementation"
63 depends on OMAP_SMARTREFLEX && TWL4030_CORE
65 Say Y to enable Class 3 implementation of Smartreflex
67 Class 3 implementation of Smartreflex employs continuous hardware
70 config OMAP_RESET_CLOCKS
71 bool "Reset unused clocks during boot"
74 Say Y if you want to reset unused clocks during boot.
75 This option saves power, but assumes all drivers are
76 using the clock framework. Broken drivers that do not
77 yet use clock framework may not work with this option.
78 If you are booting from another operating system, you
79 probably do not want this option enabled until your
80 device drivers work properly.
83 bool "OMAP multiplexing support"
87 Pin multiplexing support for OMAP boards. If your bootloader
88 sets the multiplexing correctly, say N. Otherwise, or if unsure,
92 bool "Multiplexing debug output"
95 Makes the multiplexing functions print out a lot of debug info.
96 This is useful if you want to find out the correct values of the
97 multiplexing registers.
99 config OMAP_MUX_WARNINGS
100 bool "Warn about pins the bootloader didn't set up"
104 Choose Y here to warn whenever driver initialization logic needs
105 to change the pin multiplexing setup. When there are no warnings
106 printed, it's safe to deselect OMAP_MUX for your product.
113 Say Y here if you want support for the OMAP Multichannel
114 Buffered Serial Port.
117 tristate "Mailbox framework support"
120 Say Y here if you want to use OMAP Mailbox framework support for
121 DSP, IVA1.0 and IVA2 in OMAP1/2/3.
123 config OMAP_MBOX_KFIFO_SIZE
124 int "Mailbox kfifo default buffer size (bytes)"
125 depends on OMAP_MBOX_FWK
128 Specify the default size of mailbox's kfifo buffers (bytes).
129 This can also be changed at runtime (via the mbox_kfifo_size
135 config OMAP_IOMMU_DEBUG
136 tristate "Export OMAP IOMMU internals in DebugFS"
137 depends on OMAP_IOMMU && DEBUG_FS
139 Select this to see extensive information about
140 the internal state of OMAP IOMMU in debugfs.
142 Say N unless you know you need this.
144 config OMAP_IOMMU_IVA2
148 prompt "System timer"
149 default OMAP_32K_TIMER if !ARCH_OMAP15XX
151 config OMAP_MPU_TIMER
154 Select this option if you want to use the OMAP mpu timer. This
155 timer provides more intra-tick resolution than the 32KHz timer,
156 but consumes more power.
158 config OMAP_32K_TIMER
159 bool "Use 32KHz timer"
160 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
162 Select this option if you want to enable the OMAP 32KHz timer.
163 This timer saves power compared to the OMAP_MPU_TIMER, and has
164 support for no tick during idle. The 32KHz timer provides less
165 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
166 currently only available for OMAP16XX, 24XX, 34XX and OMAP4.
170 config OMAP3_L2_AUX_SECURE_SAVE_RESTORE
171 bool "OMAP3 HS/EMU save and restore for L2 AUX control register"
172 depends on ARCH_OMAP3 && PM
175 Without this option, L2 Auxiliary control register contents are
176 lost during off-mode entry on HS/EMU devices. This feature
177 requires support from PPA / boot-loader in HS/EMU devices, which
178 currently does not exist by default.
180 config OMAP3_L2_AUX_SECURE_SERVICE_SET_ID
181 int "Service ID for the support routine to set L2 AUX control"
182 depends on OMAP3_L2_AUX_SECURE_SAVE_RESTORE
185 PPA routine service ID for setting L2 auxiliary control register.
187 config OMAP_32K_TIMER_HZ
188 int "Kernel internal timer frequency for 32KHz timer"
190 depends on OMAP_32K_TIMER
193 Kernel internal timer frequency should be a divisor of 32768,
197 bool "Use dual-mode timer"
198 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
200 Select this option if you want to use OMAP Dual-Mode timers.
202 config OMAP_SERIAL_WAKE
203 bool "Enable wake-up events for serial ports"
204 depends on ARCH_OMAP1 && OMAP_MUX
207 Select this option if you want to have your system wake up
208 to data on the serial RX line. This allows you to wake the
209 system from serial console.
212 prompt "OMAP PM layer selection"
220 bool "No-op/debug PM layer"
