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.
112 config OMAP_IOMMU_DEBUG
113 tristate "Export OMAP IOMMU internals in DebugFS"
114 depends on OMAP_IOMMU && DEBUG_FS
116 Select this to see extensive information about
117 the internal state of OMAP IOMMU in debugfs.
119 Say N unless you know you need this.
122 prompt "System timer"
123 default OMAP_MPU_TIMER
125 config OMAP_MPU_TIMER
128 Select this option if you want to use the OMAP mpu timer. This
129 timer provides more intra-tick resolution than the 32KHz timer,
130 but consumes more power.
132 config OMAP_32K_TIMER
133 bool "Use 32KHz timer"
134 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
136 Select this option if you want to enable the OMAP 32KHz timer.
137 This timer saves power compared to the OMAP_MPU_TIMER, and has
138 support for no tick during idle. The 32KHz timer provides less
139 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
140 currently only available for OMAP16XX, 24XX, 34XX and OMAP4.
144 config OMAP3_L2_AUX_SECURE_SAVE_RESTORE
145 bool "OMAP3 HS/EMU save and restore for L2 AUX control register"
146 depends on ARCH_OMAP3 && PM
149 Without this option, L2 Auxiliary control register contents are
150 lost during off-mode entry on HS/EMU devices. This feature
151 requires support from PPA / boot-loader in HS/EMU devices, which
152 currently does not exist by default.
154 config OMAP3_L2_AUX_SECURE_SERVICE_SET_ID
155 int "Service ID for the support routine to set L2 AUX control"
156 depends on OMAP3_L2_AUX_SECURE_SAVE_RESTORE
159 PPA routine service ID for setting L2 auxiliary control register.
161 config OMAP_32K_TIMER_HZ
162 int "Kernel internal timer frequency for 32KHz timer"
164 depends on OMAP_32K_TIMER
167 Kernel internal timer frequency should be a divisor of 32768,
171 bool "Use dual-mode timer"
172 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
174 Select this option if you want to use OMAP Dual-Mode timers.
176 config OMAP_SERIAL_WAKE
177 bool "Enable wake-up events for serial ports"
178 depends on ARCH_OMAP1 && OMAP_MUX
181 Select this option if you want to have your system wake up
182 to data on the serial RX line. This allows you to wake the
183 system from serial console.
186 prompt "OMAP PM layer selection"
