10 config OMAP_DEBUG_DEVICES
13 For debug cards on TI reference boards.
15 config OMAP_DEBUG_LEDS
16 def_bool y if NEW_LEDS
17 depends on OMAP_DEBUG_DEVICES
21 bool "AVS(Adaptive Voltage Scaling) support for OMAP IP versions 1&2"
22 depends on POWER_AVS && (ARCH_OMAP3 || ARCH_OMAP4) && PM
25 Say Y to enable AVS(Adaptive Voltage Scaling)
26 support on OMAP containing the version 1 or
27 version 2 of the SmartReflex IP.
28 V1 is the 65nm version used in OMAP3430.
29 V2 is the update for the 45nm version of the IP used in OMAP3630
32 Please note, that by default SmartReflex is only
33 initialized and not enabled. To enable the automatic voltage
34 compensation for vdd mpu and vdd core from user space,
36 /debug/smartreflex/sr_<X>/autocomp,
37 where X is mpu_iva or core for OMAP3.
38 Optionally autocompensation can be enabled in the kernel
39 by default during system init via the enable_on_init flag
40 which an be passed as platform data to the smartreflex driver.
42 config POWER_AVS_OMAP_CLASS3
43 bool "Class 3 mode of Smartreflex Implementation"
44 depends on POWER_AVS_OMAP && TWL4030_CORE
46 Say Y to enable Class 3 implementation of Smartreflex
48 Class 3 implementation of Smartreflex employs continuous hardware
51 config OMAP_RESET_CLOCKS
52 bool "Reset unused clocks during boot"
55 Say Y if you want to reset unused clocks during boot.
56 This option saves power, but assumes all drivers are
57 using the clock framework. Broken drivers that do not
58 yet use clock framework may not work with this option.
59 If you are booting from another operating system, you
60 probably do not want this option enabled until your
61 device drivers work properly.
64 bool "OMAP multiplexing support"
68 Pin multiplexing support for OMAP boards. If your bootloader
69 sets the multiplexing correctly, say N. Otherwise, or if unsure,
73 bool "Multiplexing debug output"
76 Makes the multiplexing functions print out a lot of debug info.
77 This is useful if you want to find out the correct values of the
78 multiplexing registers.
80 config OMAP_MUX_WARNINGS
81 bool "Warn about pins the bootloader didn't set up"
85 Choose Y here to warn whenever driver initialization logic needs
86 to change the pin multiplexing setup. When there are no warnings
87 printed, it's safe to deselect OMAP_MUX for your product.
89 config OMAP_IOMMU_IVA2
96 Select this option if you want to use the OMAP mpu timer. This
97 timer provides more intra-tick resolution than the 32KHz timer,
98 but consumes more power.
100 config OMAP_32K_TIMER
101 bool "Use 32KHz timer"
102 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
103 default y if (ARCH_OMAP16XX || ARCH_OMAP2PLUS)
105 Select this option if you want to enable the OMAP 32KHz timer.
106 This timer saves power compared to the OMAP_MPU_TIMER, and has
107 support for no tick during idle. The 32KHz timer provides less
108 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
109 currently only available for OMAP16XX, 24XX, 34XX, OMAP4/5 and DRA7XX.
111 On OMAP2PLUS this value is only used for CONFIG_HZ and
112 CLOCK_TICK_RATE compile time calculation.
113 The actual timer selection is done in the board file
114 through the (DT_)MACHINE_START structure.
117 config OMAP3_L2_AUX_SECURE_SAVE_RESTORE
118 bool "OMAP3 HS/EMU save and restore for L2 AUX control register"
119 depends on ARCH_OMAP3 && PM
122 Without this option, L2 Auxiliary control register contents are
123 lost during off-mode entry on HS/EMU devices. This feature
124 requires support from PPA / boot-loader in HS/EMU devices, which
125 currently does not exist by default.
127 config OMAP3_L2_AUX_SECURE_SERVICE_SET_ID
128 int "Service ID for the support routine to set L2 AUX control"
129 depends on OMAP3_L2_AUX_SECURE_SAVE_RESTORE
132 PPA routine service ID for setting L2 auxiliary control register.
135 bool "Use dual-mode timer"
136 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
138 Select this option if you want to use OMAP Dual-Mode timers.
140 config OMAP_SERIAL_WAKE
141 bool "Enable wake-up events for serial ports"
142 depends on ARCH_OMAP1 && OMAP_MUX
145 Select this option if you want to have your system wake up
146 to data on the serial RX line. This allows you to wake the
147 system from serial console.
150 prompt "OMAP PM layer selection"
155 bool "No-op/debug PM layer"
