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
49 bool "AVS(Adaptive Voltage Scaling) support for OMAP IP versions 1&2"
50 depends on POWER_AVS && (ARCH_OMAP3 || ARCH_OMAP4) && PM
52 Say Y to enable AVS(Adaptive Voltage Scaling)
53 support on OMAP containing the version 1 or
54 version 2 of the SmartReflex IP.
55 V1 is the 65nm version used in OMAP3430.
56 V2 is the update for the 45nm version of the IP used in OMAP3630
59 Please note, that by default SmartReflex is only
60 initialized and not enabled. To enable the automatic voltage
61 compensation for vdd mpu and vdd core from user space,
63 /debug/smartreflex/sr_<X>/autocomp,
64 where X is mpu_iva or core for OMAP3.
65 Optionally autocompensation can be enabled in the kernel
66 by default during system init via the enable_on_init flag
67 which an be passed as platform data to the smartreflex driver.
69 config POWER_AVS_OMAP_CLASS3
70 bool "Class 3 mode of Smartreflex Implementation"
71 depends on POWER_AVS_OMAP && TWL4030_CORE
73 Say Y to enable Class 3 implementation of Smartreflex
75 Class 3 implementation of Smartreflex employs continuous hardware
78 config OMAP_RESET_CLOCKS
79 bool "Reset unused clocks during boot"
82 Say Y if you want to reset unused clocks during boot.
83 This option saves power, but assumes all drivers are
84 using the clock framework. Broken drivers that do not
85 yet use clock framework may not work with this option.
86 If you are booting from another operating system, you
87 probably do not want this option enabled until your
88 device drivers work properly.
91 bool "OMAP multiplexing support"
95 Pin multiplexing support for OMAP boards. If your bootloader
96 sets the multiplexing correctly, say N. Otherwise, or if unsure,
100 bool "Multiplexing debug output"
103 Makes the multiplexing functions print out a lot of debug info.
104 This is useful if you want to find out the correct values of the
105 multiplexing registers.
107 config OMAP_MUX_WARNINGS
108 bool "Warn about pins the bootloader didn't set up"
112 Choose Y here to warn whenever driver initialization logic needs
113 to change the pin multiplexing setup. When there are no warnings
114 printed, it's safe to deselect OMAP_MUX for your product.
117 tristate "Mailbox framework support"
120 Say Y here if you want to use OMAP Mailbox framework support for
121 DSP, IVA1.0 and IVA2 in OMAP1/2/3.
123 config OMAP_MBOX_KFIFO_SIZE
124 int "Mailbox kfifo default buffer size (bytes)"
125 depends on OMAP_MBOX_FWK
128 Specify the default size of mailbox's kfifo buffers (bytes).
129 This can also be changed at runtime (via the mbox_kfifo_size
132 config OMAP_IOMMU_IVA2
135 config OMAP_MPU_TIMER
137 depends on ARCH_OMAP1
139 Select this option if you want to use the OMAP mpu timer. This
140 timer provides more intra-tick resolution than the 32KHz timer,
141 but consumes more power.
143 config OMAP_32K_TIMER
144 bool "Use 32KHz timer"
145 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
146 default y if (ARCH_OMAP16XX || ARCH_OMAP2PLUS)
148 Select this option if you want to enable the OMAP 32KHz timer.
149 This timer saves power compared to the OMAP_MPU_TIMER, and has
150 support for no tick during idle. The 32KHz timer provides less
151 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
152 currently only available for OMAP16XX, 24XX, 34XX and OMAP4/5.
154 config OMAP3_L2_AUX_SECURE_SAVE_RESTORE
155 bool "OMAP3 HS/EMU save and restore for L2 AUX control register"
156 depends on ARCH_OMAP3 && PM
159 Without this option, L2 Auxiliary control register contents are
160 lost during off-mode entry on HS/EMU devices. This feature
161 requires support from PPA / boot-loader in HS/EMU devices, which
162 currently does not exist by default.
164 config OMAP3_L2_AUX_SECURE_SERVICE_SET_ID
165 int "Service ID for the support routine to set L2 AUX control"
166 depends on OMAP3_L2_AUX_SECURE_SAVE_RESTORE
169 PPA routine service ID for setting L2 auxiliary control register.
171 config OMAP_32K_TIMER_HZ
172 int "Kernel internal timer frequency for 32KHz timer"
174 depends on OMAP_32K_TIMER
177 Kernel internal timer frequency should be a divisor of 32768,
181 bool "Use dual-mode timer"
182 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
184 Select this option if you want to use OMAP Dual-Mode timers.
186 config OMAP_SERIAL_WAKE
187 bool "Enable wake-up events for serial ports"
188 depends on ARCH_OMAP1 && OMAP_MUX
191 Select this option if you want to have your system wake up
192 to data on the serial RX line. This allows you to wake the
193 system from serial console.
