31 config OMAP_DEBUG_DEVICES
34 For debug cards on TI reference boards.
36 config OMAP_DEBUG_LEDS
38 depends on OMAP_DEBUG_DEVICES
39 default y if LEDS_CLASS
41 config OMAP_SMARTREFLEX
42 bool "SmartReflex support"
43 depends on (ARCH_OMAP3 || ARCH_OMAP4) && PM
45 Say Y if you want to enable SmartReflex.
47 SmartReflex can perform continuous dynamic voltage
48 scaling around the nominal operating point voltage
49 according to silicon characteristics and operating
50 conditions. Enabling SmartReflex reduces power
53 Please note, that by default SmartReflex is only
54 initialized. To enable the automatic voltage
55 compensation for vdd mpu and vdd core from user space,
57 /debug/voltage/vdd_<X>/smartreflex/autocomp,
58 where X is mpu or core for OMAP3.
59 Optionally autocompensation can be enabled in the kernel
60 by default during system init via the enable_on_init flag
61 which an be passed as platform data to the smartreflex driver.
63 config OMAP_SMARTREFLEX_CLASS3
64 bool "Class 3 mode of Smartreflex Implementation"
65 depends on OMAP_SMARTREFLEX && TWL4030_CORE
67 Say Y to enable Class 3 implementation of Smartreflex
69 Class 3 implementation of Smartreflex employs continuous hardware
72 config OMAP_RESET_CLOCKS
73 bool "Reset unused clocks during boot"
76 Say Y if you want to reset unused clocks during boot.
77 This option saves power, but assumes all drivers are
78 using the clock framework. Broken drivers that do not
79 yet use clock framework may not work with this option.
80 If you are booting from another operating system, you
81 probably do not want this option enabled until your
82 device drivers work properly.
85 bool "OMAP multiplexing support"
89 Pin multiplexing support for OMAP boards. If your bootloader
90 sets the multiplexing correctly, say N. Otherwise, or if unsure,
94 bool "Multiplexing debug output"
97 Makes the multiplexing functions print out a lot of debug info.
98 This is useful if you want to find out the correct values of the
99 multiplexing registers.
101 config OMAP_MUX_WARNINGS
102 bool "Warn about pins the bootloader didn't set up"
106 Choose Y here to warn whenever driver initialization logic needs
107 to change the pin multiplexing setup. When there are no warnings
108 printed, it's safe to deselect OMAP_MUX for your product.
115 Say Y here if you want support for the OMAP Multichannel
116 Buffered Serial Port.
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
137 config OMAP_IOMMU_DEBUG
138 tristate "Export OMAP IOMMU internals in DebugFS"
139 depends on OMAP_IOMMU && DEBUG_FS
141 Select this to see extensive information about
142 the internal state of OMAP IOMMU in debugfs.
144 Say N unless you know you need this.
146 config OMAP_IOMMU_IVA2
149 config OMAP_MPU_TIMER
151 depends on ARCH_OMAP1
153 Select this option if you want to use the OMAP mpu timer. This
154 timer provides more intra-tick resolution than the 32KHz timer,
155 but consumes more power.
157 config OMAP_32K_TIMER
158 bool "Use 32KHz timer"
159 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
160 default y if (ARCH_OMAP16XX || ARCH_OMAP2PLUS)
162 Select this option if you want to enable the OMAP 32KHz timer.
163 This timer saves power compared to the OMAP_MPU_TIMER, and has
164 support for no tick during idle. The 32KHz timer provides less
165 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
166 currently only available for OMAP16XX, 24XX, 34XX and OMAP4.
168 config OMAP3_L2_AUX_SECURE_SAVE_RESTORE
169 bool "OMAP3 HS/EMU save and restore for L2 AUX control register"
170 depends on ARCH_OMAP3 && PM
173 Without this option, L2 Auxiliary control register contents are
174 lost during off-mode entry on HS/EMU devices. This feature
175 requires support from PPA / boot-loader in HS/EMU devices, which
176 currently does not exist by default.
178 config OMAP3_L2_AUX_SECURE_SERVICE_SET_ID
179 int "Service ID for the support routine to set L2 AUX control"
180 depends on OMAP3_L2_AUX_SECURE_SAVE_RESTORE
183 PPA routine service ID for setting L2 auxiliary control register.
185 config OMAP_32K_TIMER_HZ
186 int "Kernel internal timer frequency for 32KHz timer"
188 depends on OMAP_32K_TIMER
191 Kernel internal timer frequency should be a divisor of 32768,
195 bool "Use dual-mode timer"
196 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
198 Select this option if you want to use OMAP Dual-Mode timers.
200 config OMAP_SERIAL_WAKE
201 bool "Enable wake-up events for serial ports"
202 depends on ARCH_OMAP1 && OMAP_MUX
205 Select this option if you want to have your system wake up
206 to data on the serial RX line. This allows you to wake the
207 system from serial console.
210 prompt "OMAP PM layer selection"
215 bool "No-op/debug PM layer"
