28 Say Y to enable AVS(Adaptive Voltage Scaling)
29 support on OMAP containing the version 1 or
30 version 2 of the SmartReflex IP.
31 V1 is the 65nm version used in OMAP3430.
32 V2 is the update for the 45nm version of the IP used in OMAP3630
33 and OMAP4430
34
35 Please note, that by default SmartReflex is only
36 initialized and not enabled. To enable the automatic voltage
37 compensation for vdd mpu and vdd core from user space,
38 user must write 1 to
39 /debug/smartreflex/sr_<X>/autocomp,
40 where X is mpu_iva or core for OMAP3.
41 Optionally autocompensation can be enabled in the kernel
42 by default during system init via the enable_on_init flag
43 which an be passed as platform data to the smartreflex driver.

56 depends on ARCH_OMAP
57 help
58 Say Y if you want to reset unused clocks during boot.
59 This option saves power, but assumes all drivers are
60 using the clock framework. Broken drivers that do not
61 yet use clock framework may not work with this option.
62 If you are booting from another operating system, you
63 probably do not want this option enabled until your
64 device drivers work properly.

88 Choose Y here to warn whenever driver initialization logic needs
89 to change the pin multiplexing setup. When there are no warnings
90 printed, it's safe to deselect OMAP_MUX for your product.

104 help
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.
110
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.
