28 config OMAP_DEBUG_DEVICES
31 For debug cards on TI reference boards.
33 config OMAP_DEBUG_LEDS
35 depends on OMAP_DEBUG_DEVICES
36 default y if LEDS_CLASS
38 config OMAP_RESET_CLOCKS
39 bool "Reset unused clocks during boot"
42 Say Y if you want to reset unused clocks during boot.
43 This option saves power, but assumes all drivers are
44 using the clock framework. Broken drivers that do not
45 yet use clock framework may not work with this option.
46 If you are booting from another operating system, you
47 probably do not want this option enabled until your
48 device drivers work properly.
51 bool "OMAP multiplexing support"
55 Pin multiplexing support for OMAP boards. If your bootloader
56 sets the multiplexing correctly, say N. Otherwise, or if unsure,
60 bool "Multiplexing debug output"
63 Makes the multiplexing functions print out a lot of debug info.
64 This is useful if you want to find out the correct values of the
65 multiplexing registers.
67 config OMAP_MUX_WARNINGS
68 bool "Warn about pins the bootloader didn't set up"
72 Choose Y here to warn whenever driver initialization logic needs
73 to change the pin multiplexing setup. When there are no warnings
74 printed, it's safe to deselect OMAP_MUX for your product.
81 Say Y here if you want support for the OMAP Multichannel
85 tristate "Mailbox framework support"
88 Say Y here if you want to use OMAP Mailbox framework support for
89 DSP, IVA1.0 and IVA2 in OMAP1/2/3.
91 config OMAP_MBOX_KFIFO_SIZE
92 int "Mailbox kfifo default buffer size (bytes)"
93 depends on OMAP_MBOX_FWK
96 Specify the default size of mailbox's kfifo buffers (bytes).
97 This can also be changed at runtime (via the mbox_kfifo_size
103 config OMAP_IOMMU_DEBUG
104 tristate "Export OMAP IOMMU internals in DebugFS"
105 depends on OMAP_IOMMU && DEBUG_FS
107 Select this to see extensive information about
108 the internal state of OMAP IOMMU in debugfs.
110 Say N unless you know you need this.
112 config OMAP_IOMMU_IVA2
116 prompt "System timer"
117 default OMAP_32K_TIMER if !ARCH_OMAP15XX
119 config OMAP_MPU_TIMER
122 Select this option if you want to use the OMAP mpu timer. This
123 timer provides more intra-tick resolution than the 32KHz timer,
124 but consumes more power.
126 config OMAP_32K_TIMER
127 bool "Use 32KHz timer"
128 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
130 Select this option if you want to enable the OMAP 32KHz timer.
131 This timer saves power compared to the OMAP_MPU_TIMER, and has
132 support for no tick during idle. The 32KHz timer provides less
133 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
134 currently only available for OMAP16XX, 24XX, 34XX and OMAP4.
138 config OMAP3_L2_AUX_SECURE_SAVE_RESTORE
139 bool "OMAP3 HS/EMU save and restore for L2 AUX control register"
140 depends on ARCH_OMAP3 && PM
143 Without this option, L2 Auxiliary control register contents are
144 lost during off-mode entry on HS/EMU devices. This feature
145 requires support from PPA / boot-loader in HS/EMU devices, which
146 currently does not exist by default.
148 config OMAP3_L2_AUX_SECURE_SERVICE_SET_ID
149 int "Service ID for the support routine to set L2 AUX control"
150 depends on OMAP3_L2_AUX_SECURE_SAVE_RESTORE
153 PPA routine service ID for setting L2 auxiliary control register.
155 config OMAP_32K_TIMER_HZ
156 int "Kernel internal timer frequency for 32KHz timer"
158 depends on OMAP_32K_TIMER
161 Kernel internal timer frequency should be a divisor of 32768,
165 bool "Use dual-mode timer"
166 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
168 Select this option if you want to use OMAP Dual-Mode timers.
170 config OMAP_SERIAL_WAKE
171 bool "Enable wake-up events for serial ports"
172 depends on ARCH_OMAP1 && OMAP_MUX
175 Select this option if you want to have your system wake up
176 to data on the serial RX line. This allows you to wake the
177 system from serial console.
180 prompt "OMAP PM layer selection"
188 bool "No-op/debug PM layer"
