34 config OMAP_DEBUG_DEVICES
37 For debug cards on TI reference boards.
39 config OMAP_DEBUG_LEDS
41 depends on OMAP_DEBUG_DEVICES
42 default y if LEDS_CLASS
44 config OMAP_SMARTREFLEX
45 bool "SmartReflex support"
46 depends on (ARCH_OMAP3 || ARCH_OMAP4) && PM
48 Say Y if you want to enable SmartReflex.
50 SmartReflex can perform continuous dynamic voltage
51 scaling around the nominal operating point voltage
52 according to silicon characteristics and operating
53 conditions. Enabling SmartReflex reduces power
56 Please note, that by default SmartReflex is only
57 initialized. To enable the automatic voltage
58 compensation for vdd mpu and vdd core from user space,
60 /debug/voltage/vdd_<X>/smartreflex/autocomp,
61 where X is mpu or core for OMAP3.
62 Optionally autocompensation can be enabled in the kernel
63 by default during system init via the enable_on_init flag
64 which an be passed as platform data to the smartreflex driver.
66 config OMAP_SMARTREFLEX_CLASS3
67 bool "Class 3 mode of Smartreflex Implementation"
68 depends on OMAP_SMARTREFLEX && TWL4030_CORE
70 Say Y to enable Class 3 implementation of Smartreflex
72 Class 3 implementation of Smartreflex employs continuous hardware
75 config OMAP_RESET_CLOCKS
76 bool "Reset unused clocks during boot"
79 Say Y if you want to reset unused clocks during boot.
80 This option saves power, but assumes all drivers are
81 using the clock framework. Broken drivers that do not
82 yet use clock framework may not work with this option.
83 If you are booting from another operating system, you
84 probably do not want this option enabled until your
85 device drivers work properly.
88 bool "OMAP multiplexing support"
92 Pin multiplexing support for OMAP boards. If your bootloader
93 sets the multiplexing correctly, say N. Otherwise, or if unsure,
97 bool "Multiplexing debug output"
100 Makes the multiplexing functions print out a lot of debug info.
101 This is useful if you want to find out the correct values of the
102 multiplexing registers.
104 config OMAP_MUX_WARNINGS
105 bool "Warn about pins the bootloader didn't set up"
109 Choose Y here to warn whenever driver initialization logic needs
110 to change the pin multiplexing setup. When there are no warnings
111 printed, it's safe to deselect OMAP_MUX for your product.
118 Say Y here if you want support for the OMAP Multichannel
119 Buffered Serial Port.
122 tristate "Mailbox framework support"
125 Say Y here if you want to use OMAP Mailbox framework support for
126 DSP, IVA1.0 and IVA2 in OMAP1/2/3.
128 config OMAP_MBOX_KFIFO_SIZE
129 int "Mailbox kfifo default buffer size (bytes)"
130 depends on OMAP_MBOX_FWK
133 Specify the default size of mailbox's kfifo buffers (bytes).
134 This can also be changed at runtime (via the mbox_kfifo_size
137 config OMAP_IOMMU_IVA2
140 config OMAP_MPU_TIMER
142 depends on ARCH_OMAP1
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
151 default y if (ARCH_OMAP16XX || ARCH_OMAP2PLUS)
153 Select this option if you want to enable the OMAP 32KHz timer.
154 This timer saves power compared to the OMAP_MPU_TIMER, and has
155 support for no tick during idle. The 32KHz timer provides less
156 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
157 currently only available for OMAP16XX, 24XX, 34XX and OMAP4.
159 config OMAP3_L2_AUX_SECURE_SAVE_RESTORE
160 bool "OMAP3 HS/EMU save and restore for L2 AUX control register"
161 depends on ARCH_OMAP3 && PM
164 Without this option, L2 Auxiliary control register contents are
165 lost during off-mode entry on HS/EMU devices. This feature
166 requires support from PPA / boot-loader in HS/EMU devices, which
167 currently does not exist by default.
169 config OMAP3_L2_AUX_SECURE_SERVICE_SET_ID
170 int "Service ID for the support routine to set L2 AUX control"
171 depends on OMAP3_L2_AUX_SECURE_SAVE_RESTORE
174 PPA routine service ID for setting L2 auxiliary control register.
176 config OMAP_32K_TIMER_HZ
177 int "Kernel internal timer frequency for 32KHz timer"
179 depends on OMAP_32K_TIMER
182 Kernel internal timer frequency should be a divisor of 32768,
186 bool "Use dual-mode timer"
187 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
189 Select this option if you want to use OMAP Dual-Mode timers.
191 config OMAP_SERIAL_WAKE
192 bool "Enable wake-up events for serial ports"
193 depends on ARCH_OMAP1 && OMAP_MUX
196 Select this option if you want to have your system wake up
197 to data on the serial RX line. This allows you to wake the
198 system from serial console.
