General informations

The Linux kernel configuration item CONFIG_POWER_AVS_OMAP has multiple definitions:

AVS(Adaptive Voltage Scaling) support for OMAP IP versions 1&2 found in arch/arm/mach-omap2/Kconfig

The configuration item CONFIG_POWER_AVS_OMAP:

• prompt: AVS(Adaptive Voltage Scaling) support for OMAP IP versions 1&2
• type: bool
• depends on: ( CONFIG_ARCH_OMAP3 || CONFIG_ARCH_OMAP4 ) && CONFIG_PM
• defined in arch/arm/mach-omap2/Kconfig
• found in Linux kernels: 5.19, 6.0–6.12

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.
