The Aspeed System Control Unit manages the global behaviour of the SoC, configuring elements such as clocks, pinmux, and reset. Required properties: - compatible: One of: "aspeed,ast2400-scu", "syscon", "simple-mfd" "aspeed,g4-scu", "syscon", "simple-mfd" "aspeed,ast2500-scu", "syscon", "simple-mfd" "aspeed,g5-scu", "syscon", "simple-mfd" - reg: contains the offset and length of the SCU memory region - #clock-cells: should be set to <1> - the system controller is also a clock provider - #reset-cells: should be set to <1> - the system controller is also a reset line provider Example: syscon: syscon@1e6e2000 { compatible = "aspeed,ast2400-scu", "syscon", "simple-mfd"; reg = <0x1e6e2000 0x1a8>; #clock-cells = <1>; #reset-cells = <1>; };
