14 config OMAP_DEBUG_DEVICES
17 For debug cards on TI reference boards.
19 config OMAP_DEBUG_LEDS
20 def_bool y if NEW_LEDS
21 depends on OMAP_DEBUG_DEVICES
25 bool "AVS(Adaptive Voltage Scaling) support for OMAP IP versions 1&2"
26 depends on POWER_AVS && (ARCH_OMAP3 || ARCH_OMAP4) && PM
29 Say Y to enable AVS(Adaptive Voltage Scaling)
30 support on OMAP containing the version 1 or
31 version 2 of the SmartReflex IP.
32 V1 is the 65nm version used in OMAP3430.
33 V2 is the update for the 45nm version of the IP used in OMAP3630
36 Please note, that by default SmartReflex is only
37 initialized and not enabled. To enable the automatic voltage
38 compensation for vdd mpu and vdd core from user space,
40 /debug/smartreflex/sr_<X>/autocomp,
41 where X is mpu_iva or core for OMAP3.
42 Optionally autocompensation can be enabled in the kernel
43 by default during system init via the enable_on_init flag
44 which an be passed as platform data to the smartreflex driver.
46 config POWER_AVS_OMAP_CLASS3
47 bool "Class 3 mode of Smartreflex Implementation"
48 depends on POWER_AVS_OMAP && TWL4030_CORE
50 Say Y to enable Class 3 implementation of Smartreflex
52 Class 3 implementation of Smartreflex employs continuous hardware
55 config OMAP_RESET_CLOCKS
56 bool "Reset unused clocks during boot"
59 Say Y if you want to reset unused clocks during boot.
60 This option saves power, but assumes all drivers are
61 using the clock framework. Broken drivers that do not
62 yet use clock framework may not work with this option.
63 If you are booting from another operating system, you
64 probably do not want this option enabled until your
65 device drivers work properly.
71 Select this option if you want to use the OMAP mpu timer. This
72 timer provides more intra-tick resolution than the 32KHz timer,
73 but consumes more power.
76 bool "Use 32KHz timer"
77 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
78 default y if (ARCH_OMAP16XX || ARCH_OMAP2PLUS)
80 Select this option if you want to enable the OMAP 32KHz timer.
81 This timer saves power compared to the OMAP_MPU_TIMER, and has
82 support for no tick during idle. The 32KHz timer provides less
83 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
84 currently only available for OMAP16XX, 24XX, 34XX, OMAP4/5 and DRA7XX.
86 On OMAP2PLUS this value is only used for CONFIG_HZ and
87 CLOCK_TICK_RATE compile time calculation.
88 The actual timer selection is done in the board file
89 through the (DT_)MACHINE_START structure.
92 config OMAP3_L2_AUX_SECURE_SAVE_RESTORE
93 bool "OMAP3 HS/EMU save and restore for L2 AUX control register"
94 depends on ARCH_OMAP3 && PM
97 Without this option, L2 Auxiliary control register contents are
98 lost during off-mode entry on HS/EMU devices. This feature
99 requires support from PPA / boot-loader in HS/EMU devices, which
100 currently does not exist by default.
102 config OMAP3_L2_AUX_SECURE_SERVICE_SET_ID
103 int "Service ID for the support routine to set L2 AUX control"
104 depends on OMAP3_L2_AUX_SECURE_SAVE_RESTORE
107 PPA routine service ID for setting L2 auxiliary control register.
109 config OMAP_SERIAL_WAKE
110 bool "Enable wake-up events for serial ports"
111 depends on ARCH_OMAP1 && OMAP_MUX
114 Select this option if you want to have your system wake up
115 to data on the serial RX line. This allows you to wake the
116 system from serial console.
