System controller node represents a register region containing a set of miscellaneous registers. The registers are not cohesive enough to represent as any specific type of device. The typical use-case is for some other node's driver, or platform-specific code, to acquire a reference to the syscon node (e.g. by phandle, node path, or search using a specific compatible value), interrogate the node (or associated OS driver) to determine the location of the registers, and access the registers directly. maintainers: - Kishon Vijay Abraham I - Roger Quadros ; #address-cells = <1>; #size-cells = <1>; ranges; serdes_ln_ctrl: serdes-ln-ctrl@4080 { compatible = "mmio-mux"; reg = <0x00004080 0x50>; }; }; ...
