40 config OMAP_DEBUG_DEVICES
43 For debug cards on TI reference boards.
45 config OMAP_DEBUG_LEDS
46 def_bool y if NEW_LEDS
47 depends on OMAP_DEBUG_DEVICES
51 bool "AVS(Adaptive Voltage Scaling) support for OMAP IP versions 1&2"
52 depends on POWER_AVS && (ARCH_OMAP3 || ARCH_OMAP4) && PM
55 Say Y to enable AVS(Adaptive Voltage Scaling)
56 support on OMAP containing the version 1 or
57 version 2 of the SmartReflex IP.
58 V1 is the 65nm version used in OMAP3430.
59 V2 is the update for the 45nm version of the IP used in OMAP3630
62 Please note, that by default SmartReflex is only
63 initialized and not enabled. To enable the automatic voltage
64 compensation for vdd mpu and vdd core from user space,
66 /debug/smartreflex/sr_<X>/autocomp,
67 where X is mpu_iva or core for OMAP3.
68 Optionally autocompensation can be enabled in the kernel
69 by default during system init via the enable_on_init flag
70 which an be passed as platform data to the smartreflex driver.
72 config POWER_AVS_OMAP_CLASS3
73 bool "Class 3 mode of Smartreflex Implementation"
74 depends on POWER_AVS_OMAP && TWL4030_CORE
76 Say Y to enable Class 3 implementation of Smartreflex
78 Class 3 implementation of Smartreflex employs continuous hardware
81 config OMAP_RESET_CLOCKS
82 bool "Reset unused clocks during boot"
85 Say Y if you want to reset unused clocks during boot.
86 This option saves power, but assumes all drivers are
87 using the clock framework. Broken drivers that do not
88 yet use clock framework may not work with this option.
89 If you are booting from another operating system, you
90 probably do not want this option enabled until your
91 device drivers work properly.
94 bool "OMAP multiplexing support"
98 Pin multiplexing support for OMAP boards. If your bootloader
99 sets the multiplexing correctly, say N. Otherwise, or if unsure,
102 config OMAP_MUX_DEBUG
103 bool "Multiplexing debug output"
106 Makes the multiplexing functions print out a lot of debug info.
107 This is useful if you want to find out the correct values of the
108 multiplexing registers.
110 config OMAP_MUX_WARNINGS
111 bool "Warn about pins the bootloader didn't set up"
115 Choose Y here to warn whenever driver initialization logic needs
116 to change the pin multiplexing setup. When there are no warnings
117 printed, it's safe to deselect OMAP_MUX for your product.
120 tristate "Mailbox framework support"
123 Say Y here if you want to use OMAP Mailbox framework support for
124 DSP, IVA1.0 and IVA2 in OMAP1/2/3.
126 config OMAP_MBOX_KFIFO_SIZE
127 int "Mailbox kfifo default buffer size (bytes)"
128 depends on OMAP_MBOX_FWK
131 Specify the default size of mailbox's kfifo buffers (bytes).
132 This can also be changed at runtime (via the mbox_kfifo_size
135 config OMAP_IOMMU_IVA2
138 config OMAP_MPU_TIMER
140 depends on ARCH_OMAP1
142 Select this option if you want to use the OMAP mpu timer. This
143 timer provides more intra-tick resolution than the 32KHz timer,
144 but consumes more power.
146 config OMAP_32K_TIMER
147 bool "Use 32KHz timer"
148 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
149 default y if (ARCH_OMAP16XX || ARCH_OMAP2PLUS)
151 Select this option if you want to enable the OMAP 32KHz timer.
152 This timer saves power compared to the OMAP_MPU_TIMER, and has
153 support for no tick during idle. The 32KHz timer provides less
154 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
155 currently only available for OMAP16XX, 24XX, 34XX and OMAP4/5.
157 On OMAP2PLUS this value is only used for CONFIG_HZ and
158 CLOCK_TICK_RATE compile time calculation.
159 The actual timer selection is done in the board file
160 through the (DT_)MACHINE_START structure.
163 config OMAP3_L2_AUX_SECURE_SAVE_RESTORE
164 bool "OMAP3 HS/EMU save and restore for L2 AUX control register"
165 depends on ARCH_OMAP3 && PM
168 Without this option, L2 Auxiliary control register contents are
169 lost during off-mode entry on HS/EMU devices. This feature
170 requires support from PPA / boot-loader in HS/EMU devices, which
171 currently does not exist by default.
173 config OMAP3_L2_AUX_SECURE_SERVICE_SET_ID
174 int "Service ID for the support routine to set L2 AUX control"
175 depends on OMAP3_L2_AUX_SECURE_SAVE_RESTORE
178 PPA routine service ID for setting L2 auxiliary control register.
180 config OMAP_32K_TIMER_HZ
181 int "Kernel internal timer frequency for 32KHz timer"
183 depends on OMAP_32K_TIMER
186 Kernel internal timer frequency should be a divisor of 32768,
190 bool "Use dual-mode timer"
191 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
193 Select this option if you want to use OMAP Dual-Mode timers.
195 config OMAP_SERIAL_WAKE
196 bool "Enable wake-up events for serial ports"
197 depends on ARCH_OMAP1 && OMAP_MUX
200 Select this option if you want to have your system wake up
201 to data on the serial RX line. This allows you to wake the
202 system from serial console.
205 prompt "OMAP PM layer selection"
