46 config OMAP_DEBUG_DEVICES
49 For debug cards on TI reference boards.
51 config OMAP_DEBUG_LEDS
53 depends on OMAP_DEBUG_DEVICES
54 default y if LEDS || LEDS_OMAP_DEBUG
56 config OMAP_RESET_CLOCKS
57 bool "Reset unused clocks during boot"
60 Say Y if you want to reset unused clocks during boot.
61 This option saves power, but assumes all drivers are
62 using the clock framework. Broken drivers that do not
63 yet use clock framework may not work with this option.
64 If you are booting from another operating system, you
65 probably do not want this option enabled until your
66 device drivers work properly.
69 bool "OMAP multiplexing support"
73 Pin multiplexing support for OMAP boards. If your bootloader
74 sets the multiplexing correctly, say N. Otherwise, or if unsure,
78 bool "Multiplexing debug output"
81 Makes the multiplexing functions print out a lot of debug info.
82 This is useful if you want to find out the correct values of the
83 multiplexing registers.
85 config OMAP_MUX_WARNINGS
86 bool "Warn about pins the bootloader didn't set up"
90 Choose Y here to warn whenever driver initialization logic needs
91 to change the pin multiplexing setup. When there are no warnings
92 printed, it's safe to deselect OMAP_MUX for your product.
99 Say Y here if you want support for the OMAP Multichannel
100 Buffered Serial Port.
103 tristate "Mailbox framework support"
106 Say Y here if you want to use OMAP Mailbox framework support for
107 DSP, IVA1.0 and IVA2 in OMAP1/2/3.
109 config OMAP_MBOX_KFIFO_SIZE
110 int "Mailbox kfifo default buffer size (bytes)"
111 depends on OMAP_MBOX_FWK
114 Specify the default size of mailbox's kfifo buffers (bytes).
115 This can also be changed at runtime (via the mbox_kfifo_size
121 config OMAP_IOMMU_DEBUG
122 tristate "Export OMAP IOMMU internals in DebugFS"
123 depends on OMAP_IOMMU && DEBUG_FS
125 Select this to see extensive information about
126 the internal state of OMAP IOMMU in debugfs.
128 Say N unless you know you need this.
131 prompt "System timer"
132 default OMAP_MPU_TIMER
134 config OMAP_MPU_TIMER
137 Select this option if you want to use the OMAP mpu timer. This
138 timer provides more intra-tick resolution than the 32KHz timer,
139 but consumes more power.
141 config OMAP_32K_TIMER
142 bool "Use 32KHz timer"
143 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
145 Select this option if you want to enable the OMAP 32KHz timer.
146 This timer saves power compared to the OMAP_MPU_TIMER, and has
147 support for no tick during idle. The 32KHz timer provides less
148 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
149 currently only available for OMAP16XX, 24XX, 34XX and OMAP4.
153 config OMAP3_L2_AUX_SECURE_SAVE_RESTORE
154 bool "OMAP3 HS/EMU save and restore for L2 AUX control register"
155 depends on ARCH_OMAP3 && PM
158 Without this option, L2 Auxiliary control register contents are
159 lost during off-mode entry on HS/EMU devices. This feature
160 requires support from PPA / boot-loader in HS/EMU devices, which
161 currently does not exist by default.
163 config OMAP3_L2_AUX_SECURE_SERVICE_SET_ID
164 int "Service ID for the support routine to set L2 AUX control"
165 depends on OMAP3_L2_AUX_SECURE_SAVE_RESTORE
168 PPA routine service ID for setting L2 auxiliary control register.
170 config OMAP_32K_TIMER_HZ
171 int "Kernel internal timer frequency for 32KHz timer"
173 depends on OMAP_32K_TIMER
176 Kernel internal timer frequency should be a divisor of 32768,
180 bool "Use dual-mode timer"
181 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
183 Select this option if you want to use OMAP Dual-Mode timers.
185 config OMAP_SERIAL_WAKE
186 bool "Enable wake-up events for serial ports"
187 depends on ARCH_OMAP1 && OMAP_MUX
190 Select this option if you want to have your system wake up
191 to data on the serial RX line. This allows you to wake the
192 system from serial console.
195 prompt "OMAP PM layer selection"
