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