2menuconfig POWER_AVS
3 bool "Adaptive Voltage Scaling class support"
4 help
5 AVS is a power management technique which finely controls the
6 operating voltage of a device in order to optimize (i.e. reduce)
7 its power consumption.
8 At a given operating point the voltage is adapted depending on
9 static factors (chip manufacturing process) and dynamic factors
10 (temperature depending performance).
11 AVS is also called SmartReflex on OMAP devices.
12
13 Say Y here to enable Adaptive Voltage Scaling class support.

15config QCOM_CPR
16 tristate "QCOM Core Power Reduction (CPR) support"
17 depends on POWER_AVS && HAS_IOMEM
18 select PM_OPP
19 select REGMAP
20 help
21 Say Y here to enable support for the CPR hardware found on Qualcomm
22 SoCs like QCS404.
23
24 This driver populates CPU OPPs tables and makes adjustments to the
25 tables based on feedback from the CPR hardware. If you want to do
26 CPUfrequency scaling say Y here.
27
28 To compile this driver as a module, choose M here: the module will
29 be called qcom-cpr

31config ROCKCHIP_IODOMAIN
32 tristate "Rockchip IO domain support"
33 depends on POWER_AVS && ARCH_ROCKCHIP && OF
34 help
35 Say y here to enable support io domains on Rockchip SoCs. It is
36 necessary for the io domain setting of the SoC to match the
37 voltage supplied by the regulators.
