28 config OMAP_DEBUG_DEVICES
31 For debug cards on TI reference boards.
33 config OMAP_DEBUG_LEDS
35 depends on OMAP_DEBUG_DEVICES
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.
94 config OMAP_IOMMU_DEBUG
95 tristate "Export OMAP IOMMU internals in DebugFS"
96 depends on OMAP_IOMMU && DEBUG_FS
98 Select this to see extensive information about
99 the internal state of OMAP IOMMU in debugfs.
101 Say N unless you know you need this.
104 prompt "System timer"
105 default OMAP_32K_TIMER if !ARCH_OMAP15XX
107 config OMAP_MPU_TIMER
110 Select this option if you want to use the OMAP mpu timer. This
111 timer provides more intra-tick resolution than the 32KHz timer,
112 but consumes more power.
114 config OMAP_32K_TIMER
115 bool "Use 32KHz timer"
116 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
118 Select this option if you want to enable the OMAP 32KHz timer.
119 This timer saves power compared to the OMAP_MPU_TIMER, and has
120 support for no tick during idle. The 32KHz timer provides less
121 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
122 currently only available for OMAP16XX, 24XX, 34XX and OMAP4.
126 config OMAP3_L2_AUX_SECURE_SAVE_RESTORE
127 bool "OMAP3 HS/EMU save and restore for L2 AUX control register"
128 depends on ARCH_OMAP3 && PM
131 Without this option, L2 Auxiliary control register contents are
132 lost during off-mode entry on HS/EMU devices. This feature
133 requires support from PPA / boot-loader in HS/EMU devices, which
134 currently does not exist by default.
136 config OMAP3_L2_AUX_SECURE_SERVICE_SET_ID
137 int "Service ID for the support routine to set L2 AUX control"
138 depends on OMAP3_L2_AUX_SECURE_SAVE_RESTORE
141 PPA routine service ID for setting L2 auxiliary control register.
143 config OMAP_32K_TIMER_HZ
144 int "Kernel internal timer frequency for 32KHz timer"
146 depends on OMAP_32K_TIMER
149 Kernel internal timer frequency should be a divisor of 32768,
153 bool "Use dual-mode timer"
154 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
156 Select this option if you want to use OMAP Dual-Mode timers.
158 config OMAP_SERIAL_WAKE
159 bool "Enable wake-up events for serial ports"
160 depends on ARCH_OMAP1 && OMAP_MUX
163 Select this option if you want to have your system wake up
164 to data on the serial RX line. This allows you to wake the
165 system from serial console.
168 prompt "OMAP PM layer selection"
176 bool "No-op/debug PM layer"
