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
30 and OMAP4430
31
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,
35 user must write 1 to
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.

53 depends on ARCH_OMAP
54 help
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.

121 Select this option if you want to enable the OMAP 32KHz timer.
122 This timer saves power compared to the OMAP_MPU_TIMER, and has
123 support for no tick during idle. The 32KHz timer provides less
124 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
125 currently only available for OMAP16XX, 24XX, 34XX and OMAP4/5.
126
127 On OMAP2PLUS this value is only used for CONFIG_HZ and
128 CLOCK_TICK_RATE compile time calculation.
129 The actual timer selection is done in the board file
130 through the (DT_)MACHINE_START structure.
