39 config OMAP_DEBUG_DEVICES
42 For debug cards on TI reference boards.
44 config OMAP_DEBUG_LEDS
45 def_bool y if NEW_LEDS
47 depends on OMAP_DEBUG_DEVICES
50 bool "AVS(Adaptive Voltage Scaling) support for OMAP IP versions 1&2"
51 depends on POWER_AVS && (ARCH_OMAP3 || ARCH_OMAP4) && PM
54 Say Y to enable AVS(Adaptive Voltage Scaling)
55 support on OMAP containing the version 1 or
56 version 2 of the SmartReflex IP.
57 V1 is the 65nm version used in OMAP3430.
58 V2 is the update for the 45nm version of the IP used in OMAP3630
61 Please note, that by default SmartReflex is only
62 initialized and not enabled. To enable the automatic voltage
63 compensation for vdd mpu and vdd core from user space,
65 /debug/smartreflex/sr_<X>/autocomp,
66 where X is mpu_iva or core for OMAP3.
67 Optionally autocompensation can be enabled in the kernel
68 by default during system init via the enable_on_init flag
69 which an be passed as platform data to the smartreflex driver.
71 config POWER_AVS_OMAP_CLASS3
72 bool "Class 3 mode of Smartreflex Implementation"
73 depends on POWER_AVS_OMAP && TWL4030_CORE
75 Say Y to enable Class 3 implementation of Smartreflex
77 Class 3 implementation of Smartreflex employs continuous hardware
80 config OMAP_RESET_CLOCKS
81 bool "Reset unused clocks during boot"
84 Say Y if you want to reset unused clocks during boot.
85 This option saves power, but assumes all drivers are
86 using the clock framework. Broken drivers that do not
87 yet use clock framework may not work with this option.
88 If you are booting from another operating system, you
89 probably do not want this option enabled until your
90 device drivers work properly.
93 bool "OMAP multiplexing support"
97 Pin multiplexing support for OMAP boards. If your bootloader
98 sets the multiplexing correctly, say N. Otherwise, or if unsure,
101 config OMAP_MUX_DEBUG
102 bool "Multiplexing debug output"
105 Makes the multiplexing functions print out a lot of debug info.
106 This is useful if you want to find out the correct values of the
107 multiplexing registers.
109 config OMAP_MUX_WARNINGS
110 bool "Warn about pins the bootloader didn't set up"
114 Choose Y here to warn whenever driver initialization logic needs
115 to change the pin multiplexing setup. When there are no warnings
116 printed, it's safe to deselect OMAP_MUX for your product.
119 tristate "Mailbox framework support"
122 Say Y here if you want to use OMAP Mailbox framework support for
123 DSP, IVA1.0 and IVA2 in OMAP1/2/3.
125 config OMAP_MBOX_KFIFO_SIZE
126 int "Mailbox kfifo default buffer size (bytes)"
127 depends on OMAP_MBOX_FWK
130 Specify the default size of mailbox's kfifo buffers (bytes).
131 This can also be changed at runtime (via the mbox_kfifo_size
134 config OMAP_IOMMU_IVA2
137 config OMAP_MPU_TIMER
139 depends on ARCH_OMAP1
141 Select this option if you want to use the OMAP mpu timer. This
142 timer provides more intra-tick resolution than the 32KHz timer,
143 but consumes more power.
145 config OMAP_32K_TIMER
146 bool "Use 32KHz timer"
147 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
148 default y if (ARCH_OMAP16XX || ARCH_OMAP2PLUS)
150 Select this option if you want to enable the OMAP 32KHz timer.
151 This timer saves power compared to the OMAP_MPU_TIMER, and has
152 support for no tick during idle. The 32KHz timer provides less
153 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
154 currently only available for OMAP16XX, 24XX, 34XX and OMAP4/5.
156 config OMAP3_L2_AUX_SECURE_SAVE_RESTORE
157 bool "OMAP3 HS/EMU save and restore for L2 AUX control register"
158 depends on ARCH_OMAP3 && PM
161 Without this option, L2 Auxiliary control register contents are
162 lost during off-mode entry on HS/EMU devices. This feature
163 requires support from PPA / boot-loader in HS/EMU devices, which
164 currently does not exist by default.
166 config OMAP3_L2_AUX_SECURE_SERVICE_SET_ID
167 int "Service ID for the support routine to set L2 AUX control"
168 depends on OMAP3_L2_AUX_SECURE_SAVE_RESTORE
171 PPA routine service ID for setting L2 auxiliary control register.
173 config OMAP_32K_TIMER_HZ
174 int "Kernel internal timer frequency for 32KHz timer"
176 depends on OMAP_32K_TIMER
179 Kernel internal timer frequency should be a divisor of 32768,
183 bool "Use dual-mode timer"
184 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
186 Select this option if you want to use OMAP Dual-Mode timers.
188 config OMAP_SERIAL_WAKE
189 bool "Enable wake-up events for serial ports"
190 depends on ARCH_OMAP1 && OMAP_MUX
193 Select this option if you want to have your system wake up
194 to data on the serial RX line. This allows you to wake the
195 system from serial console.
