Linux Kernel Configuration
└─>TI OMAP Common Features
└─>AVS(Adaptive Voltage Scaling) support for OMAP IP versions 1&2
In linux kernel since version 3.1 (release Date: 2011-10-24)  
Say Y to enable AVS(Adaptive Voltage Scaling)
support on OMAP containing the version 1 or
version 2 of the SmartReflex IP.
V1 is the 65nm version used in OMAP3430.
V2 is the update for the 45nm version of the IP used in OMAP3630
and OMAP4430

Please note, that by default SmartReflex is only
initialized and not enabled. To enable the automatic voltage
compensation for vdd mpu and vdd core from user space,
user must write 1 to
/debug/smartreflex/sr_<X>/autocomp,
where X is mpu_iva or core for OMAP3.
Optionally autocompensation can be enabled in the kernel
by default during system init via the enable_on_init flag
which an be passed as platform data to the smartreflex driver.
