36 config OMAP_DEBUG_DEVICES
39 For debug cards on TI reference boards.
41 config OMAP_DEBUG_LEDS
43 depends on OMAP_DEBUG_DEVICES
44 default y if LEDS_CLASS
46 config OMAP_SMARTREFLEX
47 bool "SmartReflex support"
48 depends on (ARCH_OMAP3 || ARCH_OMAP4) && PM
50 Say Y if you want to enable SmartReflex.
52 SmartReflex can perform continuous dynamic voltage
53 scaling around the nominal operating point voltage
54 according to silicon characteristics and operating
55 conditions. Enabling SmartReflex reduces power
58 Please note, that by default SmartReflex is only
59 initialized. To enable the automatic voltage
60 compensation for vdd mpu and vdd core from user space,
62 /debug/voltage/vdd_<X>/smartreflex/autocomp,
63 where X is mpu or core for OMAP3.
64 Optionally autocompensation can be enabled in the kernel
65 by default during system init via the enable_on_init flag
66 which an be passed as platform data to the smartreflex driver.
68 config OMAP_SMARTREFLEX_CLASS3
69 bool "Class 3 mode of Smartreflex Implementation"
70 depends on OMAP_SMARTREFLEX && TWL4030_CORE
72 Say Y to enable Class 3 implementation of Smartreflex
74 Class 3 implementation of Smartreflex employs continuous hardware
77 config OMAP_RESET_CLOCKS
78 bool "Reset unused clocks during boot"
81 Say Y if you want to reset unused clocks during boot.
82 This option saves power, but assumes all drivers are
83 using the clock framework. Broken drivers that do not
84 yet use clock framework may not work with this option.
85 If you are booting from another operating system, you
86 probably do not want this option enabled until your
87 device drivers work properly.
90 bool "OMAP multiplexing support"
94 Pin multiplexing support for OMAP boards. If your bootloader
95 sets the multiplexing correctly, say N. Otherwise, or if unsure,
99 bool "Multiplexing debug output"
102 Makes the multiplexing functions print out a lot of debug info.
103 This is useful if you want to find out the correct values of the
104 multiplexing registers.
106 config OMAP_MUX_WARNINGS
107 bool "Warn about pins the bootloader didn't set up"
111 Choose Y here to warn whenever driver initialization logic needs
112 to change the pin multiplexing setup. When there are no warnings
113 printed, it's safe to deselect OMAP_MUX for your product.
120 Say Y here if you want support for the OMAP Multichannel
121 Buffered Serial Port.
124 tristate "Mailbox framework support"
127 Say Y here if you want to use OMAP Mailbox framework support for
128 DSP, IVA1.0 and IVA2 in OMAP1/2/3.
130 config OMAP_MBOX_KFIFO_SIZE
131 int "Mailbox kfifo default buffer size (bytes)"
132 depends on OMAP_MBOX_FWK
135 Specify the default size of mailbox's kfifo buffers (bytes).
136 This can also be changed at runtime (via the mbox_kfifo_size
139 config OMAP_IOMMU_IVA2
142 config OMAP_MPU_TIMER
144 depends on ARCH_OMAP1
146 Select this option if you want to use the OMAP mpu timer. This
147 timer provides more intra-tick resolution than the 32KHz timer,
148 but consumes more power.
150 config OMAP_32K_TIMER
151 bool "Use 32KHz timer"
152 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
153 default y if (ARCH_OMAP16XX || ARCH_OMAP2PLUS)
155 Select this option if you want to enable the OMAP 32KHz timer.
156 This timer saves power compared to the OMAP_MPU_TIMER, and has
157 support for no tick during idle. The 32KHz timer provides less
158 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
159 currently only available for OMAP16XX, 24XX, 34XX and OMAP4.
161 config OMAP3_L2_AUX_SECURE_SAVE_RESTORE
162 bool "OMAP3 HS/EMU save and restore for L2 AUX control register"
163 depends on ARCH_OMAP3 && PM
166 Without this option, L2 Auxiliary control register contents are
167 lost during off-mode entry on HS/EMU devices. This feature
168 requires support from PPA / boot-loader in HS/EMU devices, which
169 currently does not exist by default.
171 config OMAP3_L2_AUX_SECURE_SERVICE_SET_ID
172 int "Service ID for the support routine to set L2 AUX control"
173 depends on OMAP3_L2_AUX_SECURE_SAVE_RESTORE
176 PPA routine service ID for setting L2 auxiliary control register.
178 config OMAP_32K_TIMER_HZ
179 int "Kernel internal timer frequency for 32KHz timer"
181 depends on OMAP_32K_TIMER
184 Kernel internal timer frequency should be a divisor of 32768,
188 bool "Use dual-mode timer"
189 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
191 Select this option if you want to use OMAP Dual-Mode timers.
193 config OMAP_SERIAL_WAKE
194 bool "Enable wake-up events for serial ports"
195 depends on ARCH_OMAP1 && OMAP_MUX
198 Select this option if you want to have your system wake up
199 to data on the serial RX line. This allows you to wake the
200 system from serial console.
