28 config OMAP_DEBUG_DEVICES
31 For debug cards on TI reference boards.
33 config OMAP_DEBUG_LEDS
35 depends on OMAP_DEBUG_DEVICES
36 default y if LEDS_CLASS
38 config OMAP_SMARTREFLEX
39 bool "SmartReflex support"
40 depends on ARCH_OMAP3 && PM
42 Say Y if you want to enable SmartReflex.
44 SmartReflex can perform continuous dynamic voltage
45 scaling around the nominal operating point voltage
46 according to silicon characteristics and operating
47 conditions. Enabling SmartReflex reduces power
50 Please note, that by default SmartReflex is only
51 initialized. To enable the automatic voltage
52 compensation for vdd mpu and vdd core from user space,
54 /debug/voltage/vdd_<X>/smartreflex/autocomp,
55 where X is mpu or core for OMAP3.
56 Optionallly autocompensation can be enabled in the kernel
57 by default during system init via the enable_on_init flag
58 which an be passed as platform data to the smartreflex driver.
60 config OMAP_RESET_CLOCKS
61 bool "Reset unused clocks during boot"
64 Say Y if you want to reset unused clocks during boot.
65 This option saves power, but assumes all drivers are
66 using the clock framework. Broken drivers that do not
67 yet use clock framework may not work with this option.
68 If you are booting from another operating system, you
69 probably do not want this option enabled until your
70 device drivers work properly.
73 bool "OMAP multiplexing support"
77 Pin multiplexing support for OMAP boards. If your bootloader
78 sets the multiplexing correctly, say N. Otherwise, or if unsure,
82 bool "Multiplexing debug output"
85 Makes the multiplexing functions print out a lot of debug info.
86 This is useful if you want to find out the correct values of the
87 multiplexing registers.
89 config OMAP_MUX_WARNINGS
90 bool "Warn about pins the bootloader didn't set up"
94 Choose Y here to warn whenever driver initialization logic needs
95 to change the pin multiplexing setup. When there are no warnings
96 printed, it's safe to deselect OMAP_MUX for your product.
103 Say Y here if you want support for the OMAP Multichannel
104 Buffered Serial Port.
107 tristate "Mailbox framework support"
110 Say Y here if you want to use OMAP Mailbox framework support for
111 DSP, IVA1.0 and IVA2 in OMAP1/2/3.
113 config OMAP_MBOX_KFIFO_SIZE
114 int "Mailbox kfifo default buffer size (bytes)"
115 depends on OMAP_MBOX_FWK
118 Specify the default size of mailbox's kfifo buffers (bytes).
119 This can also be changed at runtime (via the mbox_kfifo_size
125 config OMAP_IOMMU_DEBUG
126 tristate "Export OMAP IOMMU internals in DebugFS"
127 depends on OMAP_IOMMU && DEBUG_FS
129 Select this to see extensive information about
130 the internal state of OMAP IOMMU in debugfs.
132 Say N unless you know you need this.
134 config OMAP_IOMMU_IVA2
138 prompt "System timer"
139 default OMAP_32K_TIMER if !ARCH_OMAP15XX
141 config OMAP_MPU_TIMER
144 Select this option if you want to use the OMAP mpu timer. This
145 timer provides more intra-tick resolution than the 32KHz timer,
146 but consumes more power.
148 config OMAP_32K_TIMER
149 bool "Use 32KHz timer"
150 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
152 Select this option if you want to enable the OMAP 32KHz timer.
153 This timer saves power compared to the OMAP_MPU_TIMER, and has
154 support for no tick during idle. The 32KHz timer provides less
155 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
156 currently only available for OMAP16XX, 24XX, 34XX and OMAP4.
160 config OMAP3_L2_AUX_SECURE_SAVE_RESTORE
161 bool "OMAP3 HS/EMU save and restore for L2 AUX control register"
162 depends on ARCH_OMAP3 && PM
165 Without this option, L2 Auxiliary control register contents are
166 lost during off-mode entry on HS/EMU devices. This feature
167 requires support from PPA / boot-loader in HS/EMU devices, which
168 currently does not exist by default.
170 config OMAP3_L2_AUX_SECURE_SERVICE_SET_ID
171 int "Service ID for the support routine to set L2 AUX control"
172 depends on OMAP3_L2_AUX_SECURE_SAVE_RESTORE
175 PPA routine service ID for setting L2 auxiliary control register.
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_OMAP2PLUS
190 Select this option if you want to use OMAP Dual-Mode timers.
192 config OMAP_SERIAL_WAKE
193 bool "Enable wake-up events for serial ports"
194 depends on ARCH_OMAP1 && OMAP_MUX
197 Select this option if you want to have your system wake up
198 to data on the serial RX line. This allows you to wake the
199 system from serial console.
202 prompt "OMAP PM layer selection"
