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
Example:
syscon: syscon@1e6e2000 {
compatible = "aspeed,ast2400-scu", "syscon", "simple-mfd";
reg = <0x1e6e2000 0x1a8>;
};
