32 config OMAP_DEBUG_DEVICES
35 For debug cards on TI reference boards.
37 config OMAP_DEBUG_LEDS
39 depends on OMAP_DEBUG_DEVICES
40 default y if LEDS_CLASS
42 config OMAP_SMARTREFLEX
43 bool "SmartReflex support"
44 depends on (ARCH_OMAP3 || ARCH_OMAP4) && PM
46 Say Y if you want to enable SmartReflex.
48 SmartReflex can perform continuous dynamic voltage
49 scaling around the nominal operating point voltage
50 according to silicon characteristics and operating
51 conditions. Enabling SmartReflex reduces power
54 Please note, that by default SmartReflex is only
55 initialized. To enable the automatic voltage
56 compensation for vdd mpu and vdd core from user space,
58 /debug/voltage/vdd_<X>/smartreflex/autocomp,
59 where X is mpu or core for OMAP3.
60 Optionally autocompensation can be enabled in the kernel
61 by default during system init via the enable_on_init flag
62 which an be passed as platform data to the smartreflex driver.
64 config OMAP_SMARTREFLEX_CLASS3
65 bool "Class 3 mode of Smartreflex Implementation"
66 depends on OMAP_SMARTREFLEX && TWL4030_CORE
68 Say Y to enable Class 3 implementation of Smartreflex
70 Class 3 implementation of Smartreflex employs continuous hardware
73 config OMAP_RESET_CLOCKS
74 bool "Reset unused clocks during boot"
77 Say Y if you want to reset unused clocks during boot.
78 This option saves power, but assumes all drivers are
79 using the clock framework. Broken drivers that do not
80 yet use clock framework may not work with this option.
81 If you are booting from another operating system, you
82 probably do not want this option enabled until your
83 device drivers work properly.
86 bool "OMAP multiplexing support"
90 Pin multiplexing support for OMAP boards. If your bootloader
91 sets the multiplexing correctly, say N. Otherwise, or if unsure,
95 bool "Multiplexing debug output"
98 Makes the multiplexing functions print out a lot of debug info.
99 This is useful if you want to find out the correct values of the
100 multiplexing registers.
102 config OMAP_MUX_WARNINGS
103 bool "Warn about pins the bootloader didn't set up"
107 Choose Y here to warn whenever driver initialization logic needs
108 to change the pin multiplexing setup. When there are no warnings
109 printed, it's safe to deselect OMAP_MUX for your product.
116 Say Y here if you want support for the OMAP Multichannel
117 Buffered Serial Port.
120 tristate "Mailbox framework support"
123 Say Y here if you want to use OMAP Mailbox framework support for
124 DSP, IVA1.0 and IVA2 in OMAP1/2/3.
126 config OMAP_MBOX_KFIFO_SIZE
127 int "Mailbox kfifo default buffer size (bytes)"
128 depends on OMAP_MBOX_FWK
131 Specify the default size of mailbox's kfifo buffers (bytes).
132 This can also be changed at runtime (via the mbox_kfifo_size
138 config OMAP_IOMMU_DEBUG
139 tristate "Export OMAP IOMMU internals in DebugFS"
140 depends on OMAP_IOMMU && DEBUG_FS
142 Select this to see extensive information about
143 the internal state of OMAP IOMMU in debugfs.
145 Say N unless you know you need this.
147 config OMAP_IOMMU_IVA2
150 config OMAP_MPU_TIMER
152 depends on ARCH_OMAP1
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
161 default y if (ARCH_OMAP16XX || ARCH_OMAP2PLUS)
163 Select this option if you want to enable the OMAP 32KHz timer.
164 This timer saves power compared to the OMAP_MPU_TIMER, and has
165 support for no tick during idle. The 32KHz timer provides less
166 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
167 currently only available for OMAP16XX, 24XX, 34XX and OMAP4.
169 config OMAP3_L2_AUX_SECURE_SAVE_RESTORE
170 bool "OMAP3 HS/EMU save and restore for L2 AUX control register"
171 depends on ARCH_OMAP3 && PM
174 Without this option, L2 Auxiliary control register contents are
175 lost during off-mode entry on HS/EMU devices. This feature
176 requires support from PPA / boot-loader in HS/EMU devices, which
177 currently does not exist by default.
179 config OMAP3_L2_AUX_SECURE_SERVICE_SET_ID
180 int "Service ID for the support routine to set L2 AUX control"
181 depends on OMAP3_L2_AUX_SECURE_SAVE_RESTORE
184 PPA routine service ID for setting L2 auxiliary control register.
186 config OMAP_32K_TIMER_HZ
187 int "Kernel internal timer frequency for 32KHz timer"
189 depends on OMAP_32K_TIMER
192 Kernel internal timer frequency should be a divisor of 32768,
196 bool "Use dual-mode timer"
197 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
199 Select this option if you want to use OMAP Dual-Mode timers.
201 config OMAP_SERIAL_WAKE
202 bool "Enable wake-up events for serial ports"
203 depends on ARCH_OMAP1 && OMAP_MUX
206 Select this option if you want to have your system wake up
207 to data on the serial RX line. This allows you to wake the
208 system from serial console.
