Many SoCs allow 8*4f43646eSJianqun Xu power to be applied to or removed from portions of the SoC (io 9*4f43646eSJianqun Xu domains). This may be used to save power. This API provides the 10*4f43646eSJianqun Xu means to control such power management hardware. 11*4f43646eSJianqun Xu 12*4f43646eSJianqun Xuconfig ROCKCHIP_IO_DOMAIN 13*4f43646eSJianqun Xu bool "Enable the rockchip io domain driver" 14*4f43646eSJianqun Xu depends on IO_DOMAIN && ARCH_ROCKCHIP 15*4f43646eSJianqun Xu help 16*4f43646eSJianqun Xu Enable support for manipulating ROCKCHIP io domains via MMIO mapped 17*4f43646eSJianqun Xu registers. 18*4f43646eSJianqun Xu 19*4f43646eSJianqun Xuendmenu 20
