12 The General Register Files are a central component providing
13 special additional settings registers for a lot of soc-components.
14 In a lot of cases there also need to be default settings initialized
15 to make some of them conform to expectations of the kernel.
17 config ROCKCHIP_IODOMAIN
18 tristate "Rockchip IO domain support"
21 Say y here to enable support io domains on Rockchip SoCs. It is
22 necessary for the io domain setting of the SoC to match the
23 voltage supplied by the regulators.
25 config ROCKCHIP_PM_DOMAINS
26 bool "Rockchip generic power domain"
28 select PM_GENERIC_DOMAINS
30 Say y here to enable power domain support.
31 In order to meet high performance and low power requirements, a power
32 management unit is designed or saving power when RK3288 in low power
33 mode. The RK3288 PMU is dedicated for managing the power of the whole chip.
