Many SoCs allow power to be applied to or removed from portions of the SoC (io domains). This may be used to save power. This API provides the means to control such power management hardware. config ROCKCHIP_IO_DOMAIN bool "Enable the rockchip io domain driver" depends on IO_DOMAIN && ARCH_ROCKCHIP help Enable support for manipulating ROCKCHIP io domains via MMIO mapped registers. endmenu
